\begin_layout Title
Diary - Part Ten-C
\end_layout
\begin_layout Date
January 2025 – March 2025
\end_layout
\begin_layout Author
Linas Vepštas
\end_layout
\begin_layout Abstract
Unlike parts one through nine in this series, this one is not really about
the language-learning effort.
It is instead a private diary; a continuation of Part Ten-B, which got
over-long.
It is not curated for human consumption; I am making the assumption that
no human being will ever actually read this.
Thus, its filled with random stuff I feel like writing.
Some of it is very personal, some of it is nonsense.
Mostly, I am finding that the act of writing helps otherwise vague and
scattered thoughts quantum-collapse into a more coherent form, where I
can examine them, like a dead butterfly pinned down in a display case.
Dead words.
\end_layout
\begin_layout Abstract
Human readers are discouraged from reading this, on the grounds that there
are probably better uses of your time, than to sync your thought-patterns
onto mine own.
Live your life.
\end_layout
\begin_layout Section*
Introduction
\end_layout
\begin_layout Standard
Part Ten already got an introduction.
How many more do you want?
\end_layout
\begin_layout Subsection*
29 December 2024
\end_layout
\begin_layout Standard
It's a good time to start afresh.
In short – dafuq am I doing? I seem to be going at max RPM in first gear.
Is this supposed to be fun? I'm burning out writing the Atomese sensori-motor
code.
In the previous diary entry, I convinced myself that this was not a totally
stupid idea.
Now, I am not so sure.
\end_layout
\begin_layout Standard
One of the early visions for Atomese was to create affordances suitable
for algorithmic boostrapping.
This is a nice vision, but perhaps a mistake – and on multiple levels,
a mistake.
Perhaps I got lost in the details.
The details are a vision of computing from 100 years ago: that lambda calculus
can say anything sayable.
Updated to more modern time, we find that lambda calculs is the internal
language of Cartesian Closed Categories.
These are big words, and the bigness of them is beguiling, and I think
lie at the heart of the mistake.
\end_layout
\begin_layout Standard
Thanks to my physics/math background, it was very natural for me to dive
deeply into the microscopic details of structural atoms.
Perhaps one of my finest acheivements is coming to an understanding that
jigsaw pieces are perhaps an ideal structural element.
Jigsaw can be used to build anything.
They are more naturally expressive than lambdas, and have natural identificatio
n with tensors (and the many-world parallelisms of tensors).
Making them ideal for Bayesian priors, and other many-choice settings.
They have natural interpretation as graphs.
But they're typed, and so carry significant information (having significant
information content.) And I didn't invent them.
Many other have invented and reinvented them, over the decades.
So, all around goodness.
So why am I crying?
\end_layout
\begin_layout Standard
Well, if the goal is to build AGI ...
well, if jigsaws are like atoms (like literally, cehmical atoms) I'm daydreamin
g of creating biology from them.
Well, that's nuts: biomolecules have millios of atoms (daltons, or whatever).
I'm not gonna get there.
I might discover some cute low-level assemblies.
But that's it.
Not scalable.
\end_layout
\begin_layout Standard
OK, second example.
It's like day-dreaming of building a computer from individual transistors.
Of course, this has been done, but it took decades and tens of thousands
of engineers.
There's pretty much exactly zero infrastructure for working with jigsaws.
Like just about none at all.
So I'm at square one.
No one is interested, no one is helping.
Basically, it won't happen.
\end_layout
\begin_layout Standard
OK, third example.
It's like day-dreaming of building a neural net out of individual neurons.
Oh wait ...
well, again, this has happened.
Again, this took decades and tens of thousands of academics, grad students,
engineers, tinkerers of all kinds.
So, yes, neural nets all start with a single sum and a single sigmoid,
but the scaling is the result of a massive engineering effort.
\end_layout
\begin_layout Standard
I think jigsaws are as promising as any of these things, as a basic, basal,
low-level self-assembling structural component.
Its just that ...
I'm at square one, and no one shares my vision.
So its not going anywhere.
\end_layout
\begin_layout Standard
What to do? Well, the lesson to be taken from LLM's or, perhaps, Microsoft
Copilot, is that the world is filled with human affordances.
At this stage, in the early 21st century, it is easier to build neural
nets that can work with the available human affordances, such as coding
in java or python or whatever, than it is to create this assembly-like
intermediate language I call
\begin_inset Quotes eld
\end_inset
Atomese
\begin_inset Quotes erd
\end_inset
.
Atomese was meant to make it esy for machines.
But it starts at such a low level, that leveraging up seems single-handedly
impossible.
Just teach the computer to code in python, and be done with it.
\end_layout
\begin_layout Standard
Hah.
And there's the rub.
Current state of the art in neural nets suggests that they'll never be
able to arrive at the abstractions needed for doing the kind of reification
that humans natrually do.
So licking back and waiting for AI to magically learn how to program seems
...
well, it renders me into an observer, rather than participant.
I'd rather participate, for now.
\end_layout
\begin_layout Standard
So what can I grasp at, what can I do, to be effective? Well, I've got several
more visions.
I articulated them on the opencog wiki in the last few days, and also in
a readme file somewhere.
But again – they're visions, and from what I can tell, visions shared by
no one, so I'm like – roll up your sleeves, and get to work, you dog.
This leads to a feeling of hopelessness.
I burn out from going max RPM in first gear.
\end_layout
\begin_layout Standard
What should I do instead? When I ask this question explicitly, I rapidly
get to the general perception of well, I can rattle off all the social,
psychological, cultural, political, economic activities that humans engage
in, and they are so varied.
Somehow, being a medical doctor is worthier than sitting around doing cross-wor
ds all day.
or being a junkie.
Western culture got that part right.
But perhaps medical doctors burn out: there's always one more patient to
treat.
So, me here: there's always one more technical paper to read, one more
line of code to write.
Max RPM in first gear.
\end_layout
\begin_layout Standard
The current Western-civ definition of shifting into higher gear is to garner
money, power, fame, influence.
Gaining any of those takes effort and talent, and like any human activities,
take decades to hone one's skills.
And as that is done, I read less papers.
Perhaps this should be like atheltics: don't overtrain one muscle group,
while leaving others atrophied? I've let my power, fame, money and influence
atrophy.
And now here I am, wimpering like the old man that I am, that my ethereal
being hurts.
The physical therapist suggests some simple exercises for the weak and
dibilitated: pay the bills, read the email.
Like any ordinary person recuperating frome an injury, taking the doctors
advice is hard.
I don't want to go out and exercise, to go out and exercise and gain the
strength so I can go to the olympics of wealth, fame and power.
Unh, unh.
Cause people do what they want to do, and I am a person.
Perhaps whats-hisname from Star Wars could say

force yourself
\begin_inset Quotes erd

, but well, dafuq.
I can force myself to ride a bike up that hill in Southern Walnut Creek
bike trail.
I can force myself to do what it takes to win gold medals at the US masters
nationals.
I do NOT have to force myself to read textbooks on general relativity or
string theory, because I find that actuall fun.
I do have to force myself to pay the blls and read the emails, cause that's
not fun.
Or something.
\end_layout
\begin_layout Standard
I feel like I am procrastinating.
And, well, I am.
Because the duties that I shirk do not provide the dopamine reward that
I've grown accustomed to.
I'm a goddamn dope addict, addicted to reading math textbooks, instead
of doing whatever the fuck I should be doing.
Crap.
\end_layout
\begin_layout Standard
Worse: I engage in activities without asessing the worthiness of those activites.
Like I spent a month hacking on the 25th anniversary edition of Bigfoot.
(the i370 code base.) Its useless, cause no one but no one except maybe
Paul Edwards, and even then that;s a maybe ...
no one will ever use it and no one will ever care.
I might as well have spent the month doing crossword puzzles, or mainlining
heroin, or something.
\end_layout
\begin_layout Standard
There was one minor utility: in the back of my mind, I got to review the
landscape of operating system technology, from assemblers and compilers
to kernels, and file systems and containers.
It lead to my playing with Ceph, so now I've got my home cloud.
And its interesting to see how Ceph is multi-machine autonomous in a way
that single-machine OS'es are not.
\end_layout
\begin_layout Standard
Which brings me back to where I started: my current path of tinkering with
Atomese is not going to recreate Ceph in my lifetime.
So I'm torn.
One part of me rests completely assured that million-dimensional vectors
of jigsaws are absolutely the correct approach.
Another part of me is repelled by the daunting task of taking the next
steps.
Or mis-steps, as they may be.
A third part of me laments my wasted youth.
A fourth part of me is more than happy to also waste my waning years.
A fifth part of me is deluded into thinking that perhaps by verbalizing
into this diary, something will happen.
\end_layout
\begin_layout Standard
But is 10PM Sunday night, and I'm tired.
I think I will go do something relaxing.
I think I will got read more of David Tong's Cosmology.
It's a nice treatment.
I'd never really seen a decent treatment of FLRW before.
It's not super-complex; the lectures are aimed at undergrads.
But they're focused, concise, clear, well-written.
Unlike a lot of crap I read.
Why can't people write? I wonder if I can write.
I think I can, but no one reads what i write, so maybe my topics, my style,
the things I have to say just aren't, well, they're just not Kardashian
enough.
\end_layout
\begin_layout Standard
With that, good night, adieu.

The Big Think.
Somehow, for decades, longer, since college, before, I've avoided actually
thinking about the
\begin_inset Quotes erd
\end_inset
big question
\begin_inset Quotes erd
\end_inset
: what is AGI, really? I'm going to avoid it a bit more, with a few paragraphs
of autobiography.
\end_layout
\begin_layout Standard
I remember the first time I built something.
I stacked two blocks, one on top of another, and they didn't fall down.
I got to three even, but could not move past that.
Mother had gone shopping, I guess, and left my sister and I in the basement.
The basement was kind of a safe space: nothing there, no way to escape,
nothing to break, no way to get hurt, warm.
I must have been four.
My sister is a year and a half younger, I think she was sitting, crawling.
I tried to show her how amazing it is to stack blocks, but she seemed disintere
sted.
I think I even got her to stack two.
No more.
Actually, I think I got maybe five high.
There were arch components, and a big trangular block, for a Roman forum
look.
I might have stacked two columns, and put that on top.
See, I don't clearly remember that any more, I remember the thrill of getting
to three, and once that was mastered, the rest was down-hill.
\end_layout
\begin_layout Standard
I remember what the basement looked like.
Grey enamel floor.
Stairs in the center, no railings.
Work-bench to one side, open space to the other, and then the furnace room.
I could draw a plan, right now; I remember it photographically.
Well, I did spend a lot of time down there.
79th and Justine, Chicago, Illinois.
I remember a lot of that interior.
\end_layout
\begin_layout Standard
I remember the day I learned to read.
Fox in Sox.
Doctor Suess.
Mom had a record of that, vinyl LP.
She put it on.
Somewhere in the middle, I realized that the words I was hearing correlated
with the symbols aka words on the page.
Put it on again, from the beginning.
Sure enough! The first 3,6,9,12 words correlate perfectly! The first two
or three pages are similar, having similar arrangements of words, but subtly
different, and from those subtle differences, I could tell that the spoken
words started on page one, and not on page two or three.
That they were in order, and not backwards order, or jumbled.
The were perfectly synced, and started at the begining.
I got so busy verifying the correlations on the first three pages, that
I lost track on page four.
No matter.
Start it again.
Yes, they correlation between sound and words persists through page five.
I form a hypothesis: I bet it works that way, to the end of the book (which
seems impossibly long, but there we go...)
\end_layout
\begin_layout Standard
I remember explicitly formulating this hypothesis.
Of making this prediction.
Prediction is the wrong word.
Nor was it an
\begin_inset Quotes eld
\end_inset
a ha
\begin_inset Quotes erd
\end_inset
moment.
I mean it was, but more like,
\begin_inset Quotes eld
\end_inset
gee, I bet this goes on to the end
\begin_inset Quotes erd
\end_inset
.
Not betting with money, but more concretely: if I were to listen to the
sounds again, they would match the words.
The ability to listen to sounds again was unquestionable, a subconscious
given, not available for analysis.
Ditto the looking at the pages of the book.
These were not topics of awareness.
What was in the awareness was that if the actions were repeated, the correlatio
ns would persist.
Perhaps inference is the right word.
Prediction is the act of seeing something (visually) and knowing what will
happen next (in time).
But this correlation was not in time or space, it was abstract.
Thus, I was not predicting anything.
Rather, I made the inference that the sounds and the words are corellated.
On the third or fourth listen I got maybe ten pages in, to the part

Knox in sox on fox in box.
With a paddle.
On a noodle eating poodle.
...
a poodle battle paddle noodle eating poodle..
\begin_inset Quotes erd
\end_inset
I got tangled up in there.
I think my Mom didn't want to listen to it one more time, so that was it
for the day.
I got to finish the book, and eventually memorize it, over the next week.
But that was it, that is how I learned to read.
\end_layout
\begin_layout Standard
A very conscious process, with explicit conscious formulation of hypothesis.
Starting with a dawning awareness of correlations, the game was on: a sleuthing
, a analyszing a detective mystery: if we go back, and play the record again,
then the words wer correlate, and they will do so exactly, and not just
in some impressionistic form, but precisely.
All this was in my conscious awareness: that it could have been merely
\begin_inset Quotes eld
\end_inset
close and suggestive
\begin_inset Quotes erd
\end_inset
, and my hypothesis was that, no, it would not be just
\begin_inset Quotes eld
\end_inset
suggestive of
\begin_inset Quotes erd
\end_inset
but that it would be exact.
I was very concerned with lacunae.
What if the spoken word skipped over pages? I paid attention to flipping
the age: that the sounds, the spoken words, would correlate with what was
non the next page, not skipping a word or two, not sliding in some syllables
that preserved the beat and rhyme, but failed to actually correlate with
what was printed on the page.
All this was in my explicit conscious awareness.
You, dear reader, might think I am confabulating, but I am not.
This is what my memory functions recorded of the incident.
They recorded the process of awning awareness, the inference, the hypothesis
formulation, the explicit formulation of multiple competing hypothesis
(that the correlation was poor, inexact, skipped over words...) the surmise,
surmission, that the correlation would be exact.
The hope that it would be exact.
Lurking in the back was even a sense of disappointment: if the spoken words
failed to correlate with the text, I would be disappointed.
A grand insight would be dashed.
Reality would be random and vague and blurry.
I wanted it to be sharp.
I hoped it would be sharp.
This is the emotional side.
My memories do a poor job of recording emotions, but in this case, I know
for sure that it would have been a disappointment, if the words didn't
correlate, and that this sleuthing adventure would be quickly abandoned,
and forgotten, if this was not the case.
I had better things to do with my time, than to listen to some artistic
impressionistic verbal recital that vaguely dealt with the same topics
as the written book.
I mean, that was fun and OK-ish, but definitely weak sauce.
I could do something else.
Like maybe wander into the living room, or something.
There were lots of other interesting things to do.
Crawl under the table, or something.
\end_layout
\begin_layout Standard
Of course, I remember the floor plan.
Visually.
The radio, Blaupunkt.
The record-player, in a cabinet above, a cabinet my father had made as
a college design project.
We still have it.
It's up in the attic now.
The aluminum legs are not quite strong enough to bear the weight.
Its modern.
It looks like a Mondrian painting, but furniture.
Three open bays, a fourth bay with a black formica door.
But I wander off-topic.
Of course, everyone remembers many things, for may different reasons, in
many different ways, in all sorts of different abstraction settings, with
different kinds of focus on what was important, and what wasn't.
Some people are ruled emotionally much more; others are analytic.
I suppose I have to class myself on the analytic side.
But I'm also normal.
I'm good with the visual arts.
I like music, I could play guitar.
I like sports.
Socializing with other people is my weak spot; I don't do much of this.
i think my parents are partly responsible.
They knew I was smart, and they very much did not want me to hang out with
other kids, or, at least, other kids who were not Lithuanian.
SO I got Audrius as a good friend.
Audrius was not a genius.
But I digress; this is not meant to be about my childhood, but about AGI.
So, lets get back on track.
and that means more autobiography, before I tackle AGI head-on.
\end_layout
\begin_layout Standard
My aunt taught me how to read.
Aunt Irena.
When my parents visited, she gave me and my sister some Donald Duck comic
books to look over.
She had quite the collection.
(She also had first editions of Ancient Greek poetry, Sophocles, or something
like that.
She loved to read.
I have a photo of here, knee-deep in Lake Michigan, with two other friends,
holding a book up.
In water, With friends.
Books don't go into lakes, with water and friends.
But this is my Aunt Irena.
So...) Anyway, so my uncle walks in, and catches us red-handed: we are merely
looking at the pictures, and not actually reading the text.
And it is clarified that at least I know how to read.
My sister, maybe not quite yet.
Unclear.
But me, I can read, and my uncle is demanding in that way: you will submit
a book report.
You will read this, and next time I see you, you will submit a book report.
This is the kind of threatening demands he would make.
Take fun things and turn them into not-fun.
My aunt intervenes, I think.
She's much more gentle.
She says, don't grill them.
Never mind him.
It's OK.
But you really should read the words.
\end_layout
\begin_layout Standard
And they're right.
When you read the words to a Donald Duck comic book, the story really has
nothing at all to do with what you imagined it was about.
It's completely and totally different.
The words and the pictures kind of fail to correlate entirely.
The pictures tell one story, but the words tell a quite different one.
The pictures are only there for illustration, decoration.
They loosely, impressionistically illustrate important events in the written
text, but only loosely.
This comes as a mixture of disappointment and surprise, and an acknowledgment
of defeat.
My defense to my uncle was that I already knew what the story was, because
I could tell, by looking at the pictures.
I didn't have to read no god-damned words.
I didn't swear, of course, I didn't know any swear words.
But emotionally, it was like that.
Fuck the words, I don't need no stinkin words.
I can tell what's happening from the pictures, and goddamned pedants like
you want me to fucking suffer and read fucking words for something that's
already obvious from the pictures.
This is what went through my mind.
Fuck this shit.
Words.
Screw that.
\end_layout
\begin_layout Standard
And yet, I sort of had to acknowledge that the story plot, as told by the
pictures, was pretty friggin blurry and vague.
I spent a *lot* of time decoding those pictures, trying to figure out what
the story was, and failing.
The panels in a Donald Duck comic book DO NOT TELL A STORY.
Disney sucked, in that way.
He could illustrate, but he could not make his illustrations talk.
They were mute snapshots.
He had to fucking fall back onto words to get the point across, and those
words really for the most part had almost nothing at all to do with any
implied plot-line you could extract from the pictures.
This is what I was thinking.
This is how I thought.
Well, I wasn't directly critical of Disney, not yet, because I hadn't yet
discovered this non-correlation.
But I did read one or two or maybe three comic books that day, and I do
have to say that Disney wrecked the magic.
There was magic in the pictures, and the words fucking wrecked it.
I mean, the words were fun, and I do have to say that the plot lines were
far, far more complex and sophisticated than what the pictures told.
So, if you could gain satisfaction from reading words, then I guess that's
an OK thing, but it came at the cost of ruining the pleasure and enjoyment
of looking at the pictures.
So, yeah, Disney sucked.
\end_layout
\begin_layout Standard
I mean, I read a few more comic books in the years to come, but it was never
actually fun.
It was a pass-time.
It was an OK way to spend some time, but it was not something I looked
forward to, not something were I'd think, wow, now I get to do this, can't
wait! Disney ruined comics.
I wonder if this is an issue with Disney, and other artists don't have
this problem, or what.
But I think this stuff is invisible to adults.
Some adult somewhere would have to take active, conscious effort to do
better.
Well, look, maybe its like one of those New Yorker
\begin_inset Quotes eld

contests.
See, what Disney should have done was to draw the pictures first, and then
given them to someone else, to come up with a story and plot.
But I think he was an illustrator.
He wrote the words, first, and then just illustrated.
I have no clue if he was conscious of this.
If he was aware of this, and did this intentionally.
I'm thinking he didn't.
He thought he was creating something fun, imagined that he was creating
\begin_inset Quotes eld
\end_inset
magic kingdoms
\begin_inset Quotes erd
\end_inset
but I can personally attest that it was the opposite.
He destroyed magic.
There was magic in the pictures, and the text fucking destroyed the magic.
And the swear word
\begin_inset Quotes eld

If you don't believe me, just go to the Magic Kingdoms in Florida or California.
There's damned little, no magic in them.
They're mostly flat, boring, stupid and meaningless.
I don't understand what the fuck people see in those places.
They're just dumb.
Fuck that.
No adventure.

Don't go to the fake-Paris cafe in Disneyland.

Oh, one digression that might be worthwhile, because it explores the world
of somatic feelings.
So, as an adult, working for IBM, I'm sent to SIGGRAPH in Florida.
I book a hotel in Disneyland.
The Woodlands lodge, when it was brand new.
Construction completed just weeks earlier.
I have a late flight in, evening.
Flying sucks.
I actually planned to come a day early, to poke around, so took an evening
flight so that I would not miss too much work.
And its a long drive from the airport to Disney.
Stand in a rental car line, all that hassle.
And its hot, and its muggy, its Florida in the summertime.
And I refuse to run the A/C in the car, on the grounds of some kind of
principle, or something.
So, I'm overdressed, hot muggy, wind-blown from driving wth the windows
rolled down.
Tried, vague headache.
Lugging a heavy suitcase that hurts my hands and arms and back to lift,
hurts my legs to walk and stand straight after sitting in a car for hours.
Exhaustion.
And I walk into the lobby of the Woodlands Hotel.
And its cold.
Checkin counter.
I mean, cold.
But refreshingly cold.
And there's a scent of burning pine.
And as I'm at the counter, waiting for my room key, I'm already being transport
ed to Northern Wisconsin.
A chill in the air, a mild aroma of pine wafting through the air.
And its very relaxing.
After that drive in the Florida humidity, its the perfect antidote.
And its subtle and its gentle and its refreshing, and it feels good.
It hits the spot.
Now this, this is Disney magic.
This really worked.
This is what it took, what it feels like.
Ah.
Soothing, great, wonderful.
Relaxing, refreshing.

Well, the wonderful doesn't come until I start looking around the lobby.
OMG.
Its a cavernous Canadian, Seattle woodlands lodge.
There is a two story-tall fireplace in the corner, with a roaring fire.
To heat the place, because its frankly a bit chilly.
And it is obviously the source of that burning pine smell.
And the absurdity of it all is not lost on me: I know, I am aware that
it is like 95 and humid outside, and its like 65 and dry and piney inside,
so they've got the A/C cranked, and they are using an open fireplace to
heat the place.
Which is how it's done when you're in the Canadian woods on a cool evening,
and in Canada (or Northern Wisconsin), *all* evenings are cool.
And I'm looking around, and the whole place is decorated in Cowboys and
Indians shibboleth.
Boy-scout knives and axes.
Drawings of teepees.
And its luxury.
So one thing that catches my eye is the floor is half marble, and half
carpet, and these intermingle along curvy lines, streams.
Not straight, but meandering.
And I'm think
\begin_inset Quotes eld
\end_inset
that's pretty classy, right there That.
This is luxury
\begin_inset Quotes erd
\end_inset
I mean, the two-story fireplace in the corner, OK.
But the attention to details, the floor of marble and carpet, that was
something.
And you know what? Those curvy lines lead to somewhere.
There is a small stream in the floor.
There is a small river-stream in the floor.
It starts at the end of the lobby.
You won't find it if you don't explore.
It's not there to hit you over the head, its subtle and off to one side.
But it is definitely water, and it definitely is flowing, and its a stream,
a woodlands stream.
Like in Wisconsin.
But its late and its time to go to my room, and I've got these boyscout
themes percolating all through, coloring my emotions and perceptions and
visually smack in your face, because like someone took my Boy Scouts of
America Handbook, and literally copied pictures from it onto the walls
of this hotel.
And that is how I go to bed, go to sleep.
Transported to a wonderland.
So, yes, Disney is magic.
Done right, its magic.
\end_layout
\begin_layout Standard
I did go there, maybe a decade later.
It was run down.
Too many grimy kids scratching the paint off the walls, and puking onto
the carpet and sticking their grubby little hands into the woodlands stream.
And I think the fireplace was turned off.
But that was daytime, maybe they run the fireplace only at night.
I dunno.
Magic spells work only once.
You can't go back there again.
This is the tragedy of being caught here and now, with your memories.
There is no time-travel.
There is no rewind button.
Careful, Linas, lest your memories turn back to physics.
I finished Tong's Lecture 2 on Cosmology: Hot Universe, last night.
I like it.
Pleasant reading.
So here I am, typing these words, entering them into the future light-cone
of my personal sphere of influence in a de Sitter universe.
I digress.

\begin_layout Standard
Back on track: so my Aunt feeds me sci-fi.
I remember the first short story I ever read.
I don't remember what it was about, but I do remember reading it.
Wisconsin.
Northern Woodlands.
Nothing to fucking do there.
Boring, gotta do something.
The Donald Duck comic books suck (there's piles of them, up there) and
so I pick up an issue of Science Fiction and Fantasy Magazine.
And I pick the absolute shortest thing that I can find that isn't letters
to the editor.
And its kind of disappointing, because its long.
Like, over twenty pages.
Oi vey.
Long slog ahead.
But whatever.
I'm not gonna read another comic book, so dammit, if this is it, this is
it.
Its still early in the day, and its not like I have something better to
do.
So I read the short story.
\end_layout
\begin_layout Standard
And its not bad.
And, you know, I could read more.
(I think this is the next day.) and I think there is one more short story.
But then there is this
\begin_inset Quotes eld
\end_inset
novella
\begin_inset Quotes erd
\end_inset
.
And it is fucking seventy pages long.
And I'm not going to read that, because it is just wayyyy too fucking long.
And that sucks, and surely they could have put some short stories in there
instead, instead of this fucking long novella.
But, you know, out of desperation, I read it.
It was not even science fiction, adding insult to injury.
Thinking back, I think it was Stephen King.
Something about a man and a high tower and a dusty bottle of whiskey.
Stephen King has something with those elements.
I even think they made it into a TV novella or something.
\end_layout
\begin_layout Standard
Anyway, I'm raised on sci-fi.
Of course, the Asimov robot stories.
And not just some of them, but I think all of them.
\end_layout
\begin_layout Standard
But I also spend a large chunk of my childhood reading electronics manuals.
Why? I don't know.
There were some at the library, and it's what I picked, and I could not
tell you why I picked those instead of something else.
So that's curious: I can tell you minute details about learning to read,
but nothing at all about why I chose electronics later in life.
So I get to the school career counseling session, and you are supposed
to pick out three different career tracks: these are printed 8.5x11 cards,
and they each describe a possible career, and you are supposed to pick
out three of them, something you might want to do with your life, and discuss
them with the career counselor at the front of the room.
So I pick three: electronics design, and radio repair, and some distant
third, like maybe running a TV station, something I did not want to do,
but you have to pick three, so whatever.
And the counselor gets mad: you were supposed to pick three *different*
things, you moron, and you picked all three the same.
So it is a very very short counseling session.
He says
\begin_inset Quotes eld

Linas, the football star? Really? I don't think so.

\begin_layout Standard
So I get to college, and it is time to pick a major, and I pick physics.
Why? I can tell you exactly why.
A total and complete lack of imagination.
Sure, history and art are options.
I liked Lithuanian history, especially the knights: Karalius Mindaugas.
And Algirdas and Kestutis.
The union with the Poles, Liublino Unija, Jadwiga and all that, that kind
of sucked.
And I liked Art with a capital A.
My uncle was a world-class fine artist, painting brilliant paintings.
And its all lost.
Well, not lost: those paintings are in my mom's house, and some are now
in Kaunas, Ciurlionoio museum donation.
And some canvases in Chicago, the watch-a-ma-call-it Lithuanian museum
in, wherever that is.
I don't have much dealings there.
His paintings sit, forgotten, in a dark basement.
It sucks.
And I don't know how to fix that.
My uncle deserves wayyyyy more recognition than he's gotten.
Alas.
Someday, I'll get around to this.
But I digress.
Back to college.
I mean, I'm like really good at art, and I took four fucking years of Art
History in high school.
I know this shit.
But the college major is physics, because, well, because.
I don't think I even consider anything else, outside of these three.
All other academic fields of study are on the other side of my personal
cosmological event horizon.
Mathematics would have been a distant fourth place.
Later on I learn how to make mean, snide remarks about PoliSci, but I never
get a chance to actually say them out loud.
So physics it is.
\end_layout
\begin_layout Standard
The first-year class is a wash-out class.
Starts with 150 students in a large ampitheatre lecture hall in Ryerson.
Its already 120 by two weeks in, noticeably thinning, and maybe 70 by the
fifth week.
Half wash out in five weeks.
I'm guessing the quarter ends with about 60.
Year (two more quarters) end with maybe 50, and sophomore year starts with
45, and I think its mostly stable.
Maybe down to 40 or so, I dunno.
I'm smoking lots of pot, and partying cause that's what you do in college.
Its either that, or studying in the library from noon to closing time at
10 PM.
Fourth floor was my favorite.
The cool kids say the 3rd floor was the best.
What do I know.
I'd try the 3rd floor, time to time.
I liked the 4th better.
Front of building, by the window bays.

\begin_layout Standard
Junior year, I realize physics is boring.
I'm desperate.
I'm ready to slit my wrists.
No I'm not: that's just hyperbole, a hyperbolic statement.
It's just something you say, its not like I ever thought about wrists or
bleeding or killing myself or anything even remotely related to anything
at all like that.
But its an excellent hyperbolic statement.
I'm ready to slit my wrists, that's how boring physics is.
So I want to change my major.
To what? I see the counselor.
Well, there's PERL.
Join PERL, you can write your own major.
Do anything you fucking want, a special advisor will oversee your studies.
Sounds great! I say.
Sign me up!

\begin_layout Standard
There's just one catch.
There's requirements.
Two years Latin, one year Ancient Greek.

what, you're crazy.
PERL stands for

, and if you want to write your own major studying AI, that's in-bounds
and you can do that.
And I say, thank you but no thank you.
I sign up for a course on anthropology.
South Sea Islands, and Structuralism, and all that.
Another on child development.
Lots of Piaget.
I sit in the math library, and study books on Turing machines and Church
and Lambda calculus, my junior year.
I'm drawn to it magnetically, its like the hippest, coolest and most awesome
thing to be found in the library, and I fervently wish for a universe where
I could be transported, to study those things full time.
But I never get very far, very deep, because, you know regular homework
is, like, due, and there's only so much time for fucking around, no matter
how beguiling the promise of AI in Turing machines might be.
\end_layout
\begin_layout Standard
And one of the junior-year classes is intro to quantum mechanics.
And things get weird here.
So, first of all, its totally impenetrable.
Ugo Fano, he must be 70 by now, he's fucking old, and I'm like still a
teenager, I think 19.
Much much later I find out I'm the youngest kid in my class.
At University of Chicago.
So I guess that makes me smart.
Anyway, Ugo Fano is old and the textbook is impenetrable.
It is a hand-typed manuscript, with hand-drawings.
Published by the University of Chicago Press.
Much later, second or third quarter, one girl in the class (the only girl?
I wish I could remember her name, but I can't.
She was ranked #2 in the graduating class.
I was ranked #3.
Who was #1? Fuck if I know.
#1 was some home-schooled kid, like fourteen, who was like, you know too
fucking young to even attended the classes the rest of us did.
See, I'm smart.
Youngest kid in the college, who is actually attending classes.
Ranked #3 of all graduating physics majors.
Number fucking three.
Everything in my life, I'm number three.
It's quite humbling.
Even a kind of a curse.
I could have been just plain stupid.
Or I could have been number one and shrugged it off.
But no, I'm number three.
And still shrugging it off.
But I digress.) So she comes back from the stacks, and she's got a book
that explains what quantum spin is, cause you know its a total fucking
mystery, what the fuck is spin? And there's this glossy, hard-cover textbook,
classic crisp high-kaolin-content glossy paper textbook pages, elegant
typesetting, good layout.
Like a super-mainstream college textbook, the very model of what a textboook
should be.
And it explains spin.
And there a diagram, and equations, recognizable equations, that we understand
and somehow shed insight and understanding.
And we are both like, wtf, why can't we use this textbook for class? This
textbook is clear.
And who wrote it? Ugo Fano.
Yes.
The same guy who is teaching us now.
He wrote it 20 or 30 years earlier, published in the 1950's.
A mainstream college physics quantum mechanics textbook.
And not the only one.
I think he wrote another, too.
And instead of that, we are studying from this type-written, hand-drawn
manuscript printed on plain white paper.
This impenetrable morass of meandering re-analysis of the most fundamental
and the most basic experiments from the dawn of the atomic age, trying
to articulate quantum phenomena in a semi-classical language appropriate
for 1910 or 1920.
Thinking the way people were thinking in 1910 or 1920, before they had
figured it out.
Fano didn't say so, and we didn't know so, but in retrospect, that is what
it was.
\end_layout
\begin_layout Standard
And what was that? I think, when he got old, he realized that he did not
understand quantum either, and had no clue what spin was.
Here, the man who helped found quantum chemistry, and MO-LCAO (Molecular
Orbital=Linear Combination of Atomic Orbiitals), a man who was actually
famous for his contributions ot quantum mechanics.
He didn't understand it.
And so this typewritten manuscript was his last, best attempt to go back
to the basics, and see if we missed something.
Maybe there was a needle in the haystack.
Something we missed, something important.
If we only go back, and look at the evidence again.
And that is what he was teaching.
The raw evidence.
The experiments.
The minimalist, confusing semi-classical explanations of the experimental
results.
Confusing as shit for use youngsters.
There is a reason that mainstream college textbooks win out.
Even stupid kids can read mainstream college textbooks, and say
\begin_inset Quotes eld

I learned something from that
\begin_inset Quotes erd

Or worse:
\begin_inset Quotes eld
\end_inset
I like this textbook much better than that, it is much more clear.
\begin_inset Quotes erd
\end_inset
This dooms the unclear text.
Stupid people consign confusing things to the dustbin of history.
The University of Chicago did not publish Ugo Fano's last and greatest
attempt at explaining quantum mechanics on glossy paper with proper fonts.
They did the minimal, honorable thing to do: they at least used acid-free
paper.
It hasn't yellowed.
I still have it.
\end_layout
\begin_layout Standard
So, yeah, quantum is weird.
My senior year, I take the first-year grad-school course in quantum mechanics.
Love it.
It's great.
Quantum is fugnuts weird.
I think I wrote about the prof in this diary before: he's the one who pulls
me into his office, shuts the door, and makes me swear an oath to never-ever
talk about quantum with ordinary laymen, people who do not have a formal
education in physics.
Like you know, he was swearing me into the Manhattan Project, or something.
\end_layout
\begin_layout Standard
So AI, and those classes on anthropology, and child development psychology,
Piaget, that all pales and wastes away in the potent LSD of quantum mechanics.
We're not talking Disney Magic, here.
This is the real thing.
Not fake Paris in DisneyWorld, but the real Paris.
And Paris on LSD and shrooms.
That's what quantum was.
Except weirder.
Like my prof pointed out, it's stranger than any Hollywood script (I nod),
it's beyond the imagination of any script-writer (I nod).
Beyond the ken of any sci fi writer.
(I nod.
I want to say,

what do you take me for? A moron? Why are you telling me all these obvious

Gimme a break.) and he says: I'll tell you why I'm telling you.
And you have to swear an oath.
\end_layout
\begin_layout Standard
So yes, my studies and pursuits of AI now take a back seat to physics.
The same utter and complete lack of imagination on my part that lead me
to select physics as a college major now cause me to get a PhD in physics.
p.s.
Did I mention I finished college in less than four years? Youngest kid,
and I did it in three years and two quarters.
Youngest kid except for that home-schooled boy.
I took the last quarter to work at LASR more-or-less full time, writing
FORTRAN to analyze Pioneer-10/11 spacecraft data.
For John A.
Simpson.
I was fucking twenty.
Just turned twenty.
I was also fucking.
Lost my virginity a few years earlier, and well, more or less lived with
my girl.
Fucking all the time.
Margert Edsall.
My understanding is she's Dean of Students at Columbia in New York City.
So, not just any school, but like Ivy League.
She married her housemate Mike Parides.
Who lived in the room next door, while we fucked.
He would fall asleep with the TV on.
Poor guy.
He's an MD.
Margarets's dad was an MD.
A world-class heart and pulmonary MD.
Some Arab hired him once.
Guys in dark suits, black mustaches and mirror shades whisked him off to
a limo one night.
I was there.
They looked at me, and decided I was not a threat to Arabs.
I assume Margaret married Mike because, well, Mike could get a job in New
York, and I, well, I couldn't.
I'd be an academic loser, tossing and turning and unable to find my place
in life.
Margaret was on a track.
She knew where she was going.
She also had some talents for manipulation.
She wasn't mean or bad, or even controlling.
But she got what she wanted.
She knew how to get what she wanted.
I didn't.
I was lost and dazed and confused.
\end_layout
\begin_layout Standard
So I did undergrad in under four years, but the PhD takes five.
Not because it was hard; it wasn't.
It was easy.
But I wasn't serious.
Physics wasn't really my calling.
It was merely something I was good at.
The grass was greener on the other side.
I had an opportunity to study Chaos Theory with Per Bak at Brookhaven,
but I blew it.
I had the opportunity to study conformal field theory with Zuber in Paris,
but I blew it.
I read some preprint by some russians, apply renormalization group theory
to DNA, but who fucking cared about that? No one.
I read a significant chunk of a book on computing, semi-Thue systems and
proof theory.
But I wasn't thinking, and my housemates were like

I recall reading about the collapse of some small mom-n-pop bank in Oklahoma

It was on page twenty of section three of the New York Times.
The next day, there was another story, this time on page ten.
And again, page three, because, you see, somehow Illinois Continental had
purchased a bunch of overnight repurchase agreements from this little mom-n-pop
bank in Oklahoma.
And Illinois Continental was the largest commercial bank in all of the
United States.
So that merited page three.
A few weeks later, it was a fixture on the front page of the first section.

No more post-doc.
I had to get a job.
I did not want to do nuclear bomb design in Los Alamos.
It sickened me that this was the only employable talent that I had: making
nuclear bombs.
Whatever.
lost and dazed and confused, I fucked up.
This was the low point in my life.
Couldn't get much worse.
Got a job at IBM eventually.
So, actually, yeah, it could get worse.
I spent what, two decades fucking dazed and confused at IBM? I learned
everything, and I really mean everything that there is to know about computer
engineering at IBM.
There is not a topic anywhere in all of computer engineering that I did
not spend at least half a year on, or more.
And for what? What did it get me? The urge to slit my wrists.
Metaphorically, of course.
Fucking hated it, quit IBM an angry young man.

\begin_layout Standard
There's more to this story.
I sank even lower.
I'm recovering now, but its a bit late in life for that.
I'm sixty-five, not twenty.
I'm still smart.
I've been doing AGI for 15-plus years now.
Leveraging both physics and computer engineering, and of course, math,
to do it.
And all this time, the 15+ years I've been working on AGI, I never actually
stopped and asked
\begin_inset Quotes eld
\end_inset
what is AGI?
\begin_inset Quotes erd
\end_inset
Because it seems to be a self-evident question.
But I want to ask that question in all seriousness now.
To really explore it.
What is AGI?
\end_layout
\begin_layout Standard
So here's the catch.
It's 4PM.
It is sunny outside, and I need some exercise.
I am exhausted by the time/effort to write the above, I need to take a
break.
This is the same reason I'm not a bitcoin billionaire: it was sunny and
warm outside, I needed to take a break.
Installing that bitcoin miner would have been a cool thing to do, but I
needed a break.
So I'm going to do this to AGI, too.
I told myself I'd get back to bitcoin mining, but I never did.
I do plan to get back to AGI.
\end_layout
\begin_layout Standard
Here's the deal.
Talking and thinking about AGI won't be just a few pages or a few hours.
As I told my son this morning: physics traps us in the prison of the here
and now, the present.
It gives us things like love, which I've known intimately, and things like
evil, which I do not.
Suffice it to say that some people really do seem to be evil (and not just
stupid), and to be evil from a young age.
Or something.
This requires some intellectual effort.
And now, with AGI, we (I? no, we.) We talk of building an artificial silicon
intelligence that will occupy the same prison of here and now, and it is
to be generally intelligent, which means, to me, to know love and evil.
So the AGI topic will have to encompass that.
\end_layout
\begin_layout Standard
And, of course, I will also ramble on about state vectors and high dimensions,
and parallel Baysian priors (ahem, integrals) (Oh, I gotta copy those essays
from the opencog wiki to here.) and I will talk about neural nets and LLMs.
And of course high-dimensional vectors of jigsaws: sheafs, that is.
Sheafs of networks.
Sheaf-theoretic sheafs, and for what? The reason I have to step back and
ask
\begin_inset Quotes eld
\end_inset
what is AGI?
\begin_inset Quotes erd
\end_inset
is because I'm getting lost in these details.
Yes, blah blah agentic.
Blah-blah sensori-motor.
Blah blah world-model.
Self and not self.
And fucking free fucking will.
This diary has already witnessed my flailing about with free will, and
more than once.
And so this is the question, the narrative:
\begin_inset Quotes eld
\end_inset
What is AGI?
\begin_inset Quotes erd
\end_inset
and if the answer doesn't give proper justice and dues to love and evil,
if it doesn't give proper justice to free will and the prison of now, and
if it doesn't give justice to everything we know about computer science
and engineering and physics and math, and if that answer fails to incorporate
the reality of Wetern Civilization and Political Economy (and captialist
economy) and the affordances for humans to manipulated the world in which
they live, affordances in the sense of handles on coffee cups taht allow
me to pick up coffee cups easily without burning my hands, if the answer
to the question of AGI does not somehow encompass fucking everything, then
it is a failure.
So that's the ground rules.
\end_layout
\begin_layout Standard
Oh and one more rule, perhaps the most important of all: now what? What
is there to be done, next? I mean, in the practical, immediate, consequential
sense: what is to be done next? We've got the OODA loop.
We've started the first O
\begin_inset Quotes eld

Observe
\begin_inset Quotes erd

The second O
\begin_inset Quotes eld

Orient

well, there will be a bit of that, it will revisit old ground, so I'll
keep it brief.

I might be wrong about orientation.
The D

That's the question
\begin_inset Quotes eld

What is AGI?
\begin_inset Quotes erd

which is not so much about what AGI is, because we answered that already:
its everything.
So,
\begin_inset Quotes eld
\end_inset
Decide
\begin_inset Quotes erd
\end_inset
.
Now what, What do we do next? The Act part is easy: its a long slide downhill
again.
One foot in front of the other.
But the Orient-Decide phase: this is the trap a trap like a fly on fly-paper.
I have to be able to grasp AGI, which is, well, everything, and wrestle
it into a position where I can decide to act, and to do so, unlike that
unfortunate fly, of getting my belly stuck to the fly-paper.
This is going to be a challenge.
\end_layout
\begin_layout Standard
I thought I knew what I was going to write next, and I think perhaps I still
will.
But its nice outside, and I really must get to going.
I've spilt too many words.
Toodle-oo.

\begin_layout Standard
Oh, I am going to eat an apple first.
So one or two more paragraphs.
\end_layout
\begin_layout Standard
First, lets get out of the way some basics: an AI has to be agentic.
But a cruise missile is agentic, too.
So this is where free will gets tangled in.
I'm not sure I want to do that tangle, but it might be unavoidable.
Classic AI is focused on rational inference, deduction.
And I guess this is OK.
When I learned to read Dr.
Seuss, I was creating rational, inferential hypothesis about how my local
sensory environment worked.
And I was conscious of making those hypothesis.
I recorded them in memory as my main intellectual activity.
The actual
\begin_inset Quotes eld
\end_inset
learning to read
\begin_inset Quotes erd
\end_inset
was a side-show, a pleasant distraction.
The intellectual heavy-lifting was the decision to look for correlations
between sight and sound.
\end_layout
\begin_layout Standard
And so we can weave this together to form the first lesson of AGI.
We can create a system capable of reasoning and deduction, in the very
classical AI sense, but the result might just be a cruise missile.
Feeling-less, emotionless, formal deduction towards an end and then boom.
We can build these kinds of formal reasoning systems, but this is not quite
exactly what we want to identify with as
\begin_inset Quotes eld
\end_inset
being alive
\begin_inset Quotes erd
\end_inset
.
Cruise missiles don't fall in love, nor would formal reasoning systems.
Now, I employed a formal reasoning system, when I learned how to read.
But I would like to say I am not a cruise-missile.
Now, nature gave me a brain that allowed me to perform the activities of
analyzing my environment, and thereby getting drawn into the activity of
learning to read.
But there was more: I was bored.
I had nothing better to do.
Well, maybe I did.
Maybe I could have crawled around under the dining room table, which is
a pretty marvelous architectural space, with all those columns of chair
legs and table legs all about, a large open central atrium at the center
of the table.
A table cloth forming a curtain along the edges.
Humans like to wander around in Medieval Catholic Cathedrals.
They like to shop at malls with atriums.
Even hotels are built like that.
So crawling under the living room dining table is a thing, a real thing,
and a valid pursuit as an alternative to deploying my intellectual abilities
to discern sight and sound, to correlate the printed and spoken word in
a Dr.
Suess book.
And cruise missiles don't get bored, and cruise missiles don't crawl under
tables, and cruise missiles do not employ their deductive, theorem-proving,
inference and correlation engines to learn to read.
Because, I guess, cruise missiles don't get bored.

\begin_layout Standard
So, yes, the classic AI concept of
\begin_inset Quotes eld
\end_inset
logical reasoning
\begin_inset Quotes erd
\end_inset
is important.
But its not everything.
And being an agent in the world is important, but its not everything.
Having a world model is important, but not everything.
The fucking thermostat has a one-bit model of the world: on or off, and
it has the agential motor control of a header, coupled to a thermometric
sensor.
Does a thermostat have free will? The conventional, mainstream answer would
be no.
Does a thermostat get bored? I think not.
\end_layout
\begin_layout Standard
So where does free will and boredom come from? I don't know.
But one more aside first.
Liebniz had the idea of monads, in pursuing the question of intelligence:
splitting up intelligence into smaller and smaller pieces, and so we get
panpsychism.
The thing is, Liebniz did not know about phase transitions.
I've already talked about percolation in this diary.
Less than a certain fracture, oil does not flow.
More than that, it does.
And so with intelligence.
There is a phase transition, below which there is no intelligence, and
above which there is.
We do not know where that phase transition is.
And so perhaps that is one of the central questions of AGI: where is that
phase transition? And where are cruise missiles located with respect to
that transition? Or, fuck all, ants.
Or amoeba.
Yikes!

\begin_layout Standard
Later in the day.
Post shower.
What am I doing here? Writing a diary, obviously.
Not science.
Nothing I write here conforms to any conventional standards of science.
Nothing would pass peer review.
Amateur philosophy? See, the problem is most famous philosophers were crackpots.
Smart, brilliant, even, but making inferences far beyond the ken of science.
Give them some credit I guess, for venturing into the unknown.
Subtract points for making assured claims with nothing but hand-waving
for support.
So I don't want to do that.
Feynmann might advise
\begin_inset Quotes eld
\end_inset
shut up and calculate
\begin_inset Quotes erd
\end_inset
, but I already calculate a lot, so coming up for air, and asking
\begin_inset Quotes eld
\end_inset
why calculate this and not that?
\begin_inset Quotes erd
\end_inset
seems like a legit thing to do.
\end_layout
\begin_layout Standard
The problem with saying
\begin_inset Quotes eld
\end_inset
intelligence appears on one side of a phase transition
\begin_inset Quotes erd
\end_inset
is that we don't have a coherent definition of intelligence.
Clearly animals have it.
Is it limited to neural nets? One can make coherent arguments that it is
not.
But is the behavior of slime molds
\begin_inset Quotes eld
\end_inset
intelligent
\begin_inset Quotes erd
\end_inset
? One slides down a panpsychic slide, attributing intelligence, or fractions
thereof, to simpler and simpler systems.
There's no obvious phase transition in there, somewhere.
\end_layout
\begin_layout Standard
What about free will? A few weeks earlier, in this diary, I came to conclusion,
arguably total nonsense and hallucination, that free will arises at a Cauchy
horizon.
Now this is meant to be taken not literally, but metaphorically, but also
meta-literally, in that there might be differentiable, causal structures
appearing in our brains that have singularaties, singular solutions.
So, first lets regurgitate the conventional reasons why my idea here is
fundamentally bad.
First, one hand-waves,
\begin_inset Quotes eld
\end_inset
quantum gravity
\begin_inset Quotes erd
\end_inset
, implying that if we had a theory of quantum gravity, then the singularities
(in black holes) go away, and everything is hunky-dory, and no more Cauchy
horizon, tah-dah.
But that's physics.
In math, we still have the issue that we can write down systems of equations,
that happen to have applicability to physics, but those systems of equations
admit solutions that are wonky.
Quantum gravity does not alter the math one whit.
The formal mathematical phenomena remains.
\end_layout
\begin_layout Standard
What makes the Cauchy horizon interesting is that its not a set of measure
zero.
We've got a gazillion examples of singularities on the complex plane, but
any geodesic-like curve one could draw, well most of them would have to
bump into a set of measure zero.
Now, there's some fascinating descent into the theory of the sizes of things,
which promptly leads to the Axiom of Choice, and to Borel Hierarchies,
and Cohen's forcing and all that.
Wikedly interesting stuff.
But the Cauchy horizon is not like that: living between the cracks.
The Cauchy horizon is big and bold and measure-theoretically large.
There's no Alexander's horns here, No knots sitting the three-spaces that
bound 4-spheres.
The horizon is big and bold and in your face.
Its not going away.
\end_layout
\begin_layout Standard
So my question is: are there any dynamical systems, aside from gravity,
that exhibit Cauchy horizons, and might any of those dynamical systems
appear in settings where intelligence arises? Can I build some mechanical
or fluid-dynamic system, some analog, in which there is a Cauchy horizon?
I'm thinking yes, I can.
Well, maybe not me, but in principle, and maybe it is doable, and maybe
someone has done it.
Gonna search-engine that later.
Say its doable, then are there any biological systems that would have that?
We could go all reductionist here, but that's absurd because it would imply
that we'd need quantum gravity to explain biology, and that is a non-starter.
But still, are there any systems in nature, outside of the setting of gravitati
on, that exhibit a Cauchy horizon? If so, then can I ascribe this some property
of free will? Anyone who reads this and is smart enough to understand what
I'm saying will say
\begin_inset Quotes eld
\end_inset
fuck no, Linas, that's crazy, that's wrong.
You're nuts.
\begin_inset Quotes erd
\end_inset
So whatever.
fuck you, too.
See, I'm looking for free will, because if I can find that, it provides
a workable definition of intelligence: things that have free will are intellige
nt, no matter how small and simple they are.
\end_layout
\begin_layout Standard
OK, so here I anticipate another obvious objection.
I can hear it now:
\begin_inset Quotes eld
\end_inset
Linas you are talking about a random number generator, and mechanical systems
hooked up to random number generators are not intelligent.
\begin_inset Quotes erd
\end_inset
And this is true.
But the Cauchy horizon is not a random number generator.
I want to argue more: it is an all-possibilities generator.
\end_layout
\begin_layout Standard
So here.
Conventionally, all-possibilities appear in the partition function:
\begin_inset Formula
\[
Z=\int\left[d\phi\right]\exp i\mbox{Action}
\]
\end_inset
Since the action contains derivatives, the discontinuous possibilities get
a weighting of zero and don't contribute.
Now, there are severe measure-theoretic difficulties plaguing the partition
function, but that never stopped the physics community.
Some what I'm now saying is, what if the action doesn't suppress a sizable
number of non-differentiable field configurations
\begin_inset Formula $\phi$
\end_inset
? Yes, of course, I'm piling on a mathematically ill-defined idea on top
of something that is already ill-defined when its behaving nicely.
What if free will and choice are those things that glue together the disparate
universes?
\end_layout
\begin_layout Standard
To be clear on terminology: a single choice of
\begin_inset Formula $\phi$
\end_inset
is a
\begin_inset Quotes eld
\end_inset
universe
\begin_inset Quotes erd
\end_inset
; universes and
\begin_inset Formula $\phi$
\end_inset
are in one-to-one correspondence, and the integral
\begin_inset Formula $\int\left[d\phi\right]$
\end_inset
is an integral over all universes.
The exp i Action just gives the weighting or likelihood of that universe
contributing to the partition function.
FWIW, Bayesian priors work exactly like this.
Now, by convention, one is to imagine that all of these distinct
\begin_inset Formula $\phi$
\end_inset
are entirely independent of one-another.
Nothing one can do in one can influence another.
Perhaps oe imagines the
\begin_inset Formula $\phi$
\end_inset
as sheets of paper, stacked.
Close, but nothing written on one page bleeds to another.
That's the conventional view.
\end_layout
\begin_layout Standard
Now what if, instead, the Cauchy horizon (or it's metaphorical replacement)
is where all these sheets come together? The hand-waving argument would
be that its like a singularity, say, the location
\begin_inset Formula $z=0$
\end_inset
in the complex plane for
\begin_inset Formula $\log z$
\end_inset
.
If you sit on a curve and fly into
\begin_inset Formula $z=0,$
\end_inset
you don't die, you just come out on every or any other sheet.
If there's going to be a conservation of curves, then you're allowed to
come out on any sheet of your choosing, but only one.
What is that? A random–number choice? A flip-coin choice? Some axiom-of-choice
thing? I don't know.
I don't think its a
\begin_inset Quotes eld
\end_inset
random number
\begin_inset Quotes erd
\end_inset
and I don't know what it means
\begin_inset Quotes eld
\end_inset
to choose
\begin_inset Quotes erd
\end_inset
in this situation.
But this is an example of where a singular point glues together many sheets.
But, you say,
\begin_inset Quotes eld
\end_inset
those sheeets were never independent universes.
You could always get from one to the other by circling around the pole,
gaining a factor of
\begin_inset Formula $2\pi i$
\end_inset
each time around
\begin_inset Quotes erd
\end_inset
.
And, yeah, well covering spaces tend to be simply connected.
Or perhaps that's the definition of a covering space: its that simply-connected
thing.
\end_layout
\begin_layout Standard
I dunno.
Perhaps I've gone off the deep end.
But it seems like free will needs this kind of lugubrious theorizing, because
otherwise, we are trapped with the nitwits who insist we don't have free
will and its all just random numbers, but those people are nitwits.
And they say, never argue with a fool, because the onlookers won't be able
to tell the difference.
So I'm not gonna argue with those fools.
Instead I'll do some vague mathematical fantasizing.
But really.
I think part of what I sketch above has legs.
I think something can be made of it.
Tightened up, made concrete.
\end_layout
\begin_layout Standard
But this puts us in a chicken-and-egg scenario.
If intelligent systems are exactly those that have free will, and I cannot
give a workable definition of free will, then I'm hosed again.
There are others, who are not nitwits, who think panpsychism is the answer.
And anyway, its not like the panpsychists can offer up any kind of theoretical
mechanics that allows a workable definition of intelligence to be coded
up in software.
\end_layout
\begin_layout Standard
So I seem to hit a dead end here.
One that I've hit before.
Although this time, I think I made a tiny amount of progress.
\end_layout
\begin_layout Standard
Are there other ways of thinking about AGI? Well, I suppose I could take
a more mundane and pedestrian view.
Lets take a moment to walk through those.
\end_layout
\begin_layout Standard
So one is the agentic system.
A system that has a model of the world, a distinct inside and outside,
a sensori-motor system.
But we've already noted that thermostats and cruise missiles have this,
and I don't want to give those any ascriptions of being alive or intelligent.
\end_layout
\begin_layout Standard
Then there's explosive replicators.
DNA embodied in bacteria, etc.
explosively replicate as long as there's food.
And conventionally, we say bacteria are alive.
So I'm OK with saying explosive replicators are alive.
But that's also not AGI.
I can't build a computer model of a bacterium and pass it off as AGI, because...
because why? Because it cannot be hooked up to google and work as an oracle
for answering questions.
\end_layout
\begin_layout Standard
So is an oracle for answering questions, is that AGI? Well clearly, good
AGI would be an oracle (well, oracle-like in the informal sense, not the
computer-science sense).
But the converse ain't true.
Oracles aren't AGI.
\end_layout
\begin_layout Standard
I felt I was onto something, when I started talking about boredom, and love,
and evil.
Love is ...
well, love can be explained away as some limbic, somatic, reptilian-brain
response for procreation, but anyone who has been in love knows that this
is an inadequate, mechanistic explanation offered up by nitwits who like
to pretend that they're know-it-alls.
I can't speak for the poets, but the movie
\begin_inset Quotes eld
\end_inset
The Fifth Element
\begin_inset Quotes erd
\end_inset
with Bruce Willis and Milla Jovovich does get the general nature of the
thing correct.
\end_layout
\begin_layout Standard
Dafuq.
I used the word lugubrious.
I can use it again.
Wander down the hallways of love, boredom and evil and kind of not get
any closer to a workable definition of AGI than I didn't have before.
Is it like Art?
\begin_inset Quotes eld
\end_inset
I can't define it, but I know it when I see it?
\begin_inset Quotes erd
\end_inset
But I'm not trying to reduce Art to an algorithm.
I am trying to reduce AGI to an algorithm but it seems right up there with
trying to reduce love, boredom and evil to an algorithm.
I mean, if you can't define it, you can't create software that works at
that level.
\end_layout
\begin_layout Standard
And the risks are equally obvious: like creating that 18th century robotic
schoolboy, sitting at his desk writing schoolwork: a simulacrum can be
created, but that's not the
\begin_inset Quotes eld
\end_inset
real thing
\begin_inset Quotes erd
\end_inset
.
The Polish sci-fi writer, Stanislaw Lem, has some story where reality is
shown to be some LP recording, the mechanism of which is dicey and jamming.
I can build a simulacrum of love, but that's not love.
Again, we slip into philosophy.
I had a book, while still a teen, Daniel Dennet.
It was OK.
It did not light my fire.
But it did illustrate one story with a cute robotic mouse with winking
glowing LED eyes, and cooing sounds, and the protagonist is asked to smash
it with a hammer.
Its just a freakin robot, but we have this mammalian gut reaction to little
furballs.
There's even a TV commercial, from Ikea, that features an old sad desk
lamp abandoned in the rain by the garbage.
And a full length feature film, Brave Little Toaster, the ending of which
is heart-rending.
So these are the mammalian, limbic, somatic shadows of existence that we
are immersed in.
And my definition of AGI says that it too must partake of this world.
And of course, I can create some software that claims that it does, but
this is like that Star Trek episode where Data is placed on trial, accused
of not being an actual being, of being a machine.
\end_layout
\begin_layout Standard
Where's the phase transition to being-ness? Are you getting bored by this?
Because I am.
Clearly mammals are beings, and we do down that path and end up at panpsychism
again.
\end_layout
\begin_layout Standard
You want to know how crazy I am? I'll tell you how crazy I am.
If the universe doesn't stop me, first.
Every time I'm about to do something stupid, the dog barks, and I say to
myself,
\begin_inset Quotes eld
\end_inset
this is the universe reminding me to stop doing this stupid thing
\begin_inset Quotes erd
\end_inset
.
And I'm typing this on a laptop with a shitty keyboard and a shitty touch-pad,
and I'm making vast amounts of typos due to the mechanical misbehavior
of this system vs.
my hands.
and every time I'm about to type something really exceptionally good, it
gets tangled up, and again I think: this is the universe trying to stop
me from spilling it's secrets.
That's how crazy I am.
I get those micro-thoughts, and I give them credence and credibility just
long enough to wonder if its true.
Because you know it could be.
Who the fuck knows.
The universe really could be fucking with me like that, because who is
to say it isn't.
We already have the Mandela effect.
I didn't invent it, but I do suffer from it.
I remember Nelson Mandela dying in a South African prison back in the 1980s
so what the fuck is all this about him still being alive and all that?
WTF Really? Maybe universes do cross over, or maybe the combination of
statistics, news reporting and neuroscience just makes me victim to a mass
delusion.
Who is to say?
\end_layout
\begin_layout Standard
Oh, and then there's math.
I might have touched on this a bit in this diary, but really I could do
more.
Math is a potent hallucinogen.
I don't feel like explaining this right now, but for a quick tour, look
at what people said about the Cantor set, and what he did.
It's crazy-hallucinatory.
Obviously.
Then there's the various paradoxes of measurability.
Say the Banach-Tarski paradox.
Crazy shit.
There's lots more.
Anything to with infinity.
I think I've mentioned before the insanity of weak convergence in Hilbert
spaces.
QM is insane mostly because of this one thing, but that means that the
problem lies not with QM, but with weak convergence in Hilbert spaces,
which is the root cause of quantum weirdness.
So its not the physics that's insane, its the math.
And so if math, the most staid, assured, unassailable, confident rock-hard
foundation-stone of all things knowable: I mean really, who is going to
argue that 2+2 isn't 4? This is a fact 2+2=4 and nothing you can do can
change that.
Its the rock-hard foundation.
And that foundation includes fucking goddamned fucking prime numbers.
And Banach-Tarski.
And weak convergence in Hilbert spaces.
And axioms of large cardinals.
And Borel hierarchies.
So fuck me, fuck that, math is fucking insane.
Our foundation-stone of reality, 2+2=4, is simply the logo stamped on a
universe-sized tablet of LSD.
And fuck me, what, you want me to algorithmicize this, and build you an
AGI? I homunculus based on the the mystical elements of the Kaballah? Really?
You don't need to get mystical.
The mystical is already here, right now.
Pervasive and permeating pan-mysticism.
Sheesh.
\end_layout
\begin_layout Standard
So I must bring tonight's OODA loop of exploring AGI to an end.
The observe and orient stuff ended with disorientation, and identified
the proximal cause of that disorientation.
Its built into the fucking math.
So, deeper than being built into the fucking universe, its built into the
fucking math.
Excuse the swear words, but I know obscenity when I see it, and math is
obscene.
\end_layout
\begin_layout Standard
Decide and Act.
Well, the mundane decision is to tough it out.
Put on that heavy back-pack, tie your boots and go out into that storm.
Hump it over the mountain.
Metaphorically, this means go out and read more academic journal articles,
and participate in the day-today quotidian intellectual activities of the
social world around me.
This is, I guess, an admission of defeat.
Not that I was ever expecting to win.
But laser-like focus on a narrow topic is an excellent way of making dramatic
progress, and I am anything but laser-like here.
\end_layout
\begin_layout Standard
Another analogy.
I could moan about number theory here, instead of AGI.
Or I could just go out and do it.
I think I did pretty well with the beta transform: hundreds of pages of
laser-like, focused, insightful results.
And no one cares because who the fuck cares about iterating
\begin_inset Formula $\beta x\mod1$
\end_inset
? Almost no one.
Maybe more than the number of people who care about this diary.
Because the beta transform, the iterated
\begin_inset Formula $\beta x\mod1$
\end_inset
is considered to be unimportant.
And see, that is my dilemma.
I could spend the waning years of my life making sharp, insightful progress
on narrow topics that are not important.
Or I could moan about the inaccessibility and ineffability of AGI.
Or I could just fucking give up, and just do something that would bring
me closer to nvidia gpus and weights and shut up and calculate, as Feynmann
would say.
Or I could cast about.
Because, see, all these other things are boring.
I don't quite really want to do them, because they're not ...
they're not worthy of my time.
They're not a valid activity to while away the years.
By contrast, moaning about the ineffability of AGI into this diary does
seem like something worthwhile.
\end_layout
\begin_layout Standard
Let me be more direct.
I think there's something here, and I think I could even make a bit of
progress, if I could get my hands on it.
But like the four-year-old stacking blocks, the blocks keep fumbling out
of my hands.
Something, something.
Agential sensori-motor.
Something something category theoretic.
These blocks.
I can almost assemble them.
And then the self doubts: I assembled some blocks.
Is that a house that can be lived in? Is it a Roman coliseum? No.
Is it AGI? err.
Fuck.
The blocks keep slipping away.
But I think I've almost got my hands in it.
If I just try a bit more.
Something something Basal cognition.
\end_layout
\begin_layout Standard
Well, reading more is really not a bad idea.
It takes me back into the first O of OODA: more observation.
Its a deferral of decide and act.
Its more orientation.
How much longer to decide and act? What's there to decide, if I can't figure
out what the fucking problem is? I'll sleep on it.
\end_layout
\begin_layout Standard
I finished Tong's Lecture 2 on cosmology Lecture 3 awaits.

\begin_layout Standard
Oh, footnote.
I'm loosely spell checking above, and Chinese Room pops into my mind.
I always hated the Chinese room argument, I thought it was dumb.
I see why some people feel like its worthwhile.
But those people are just dumb.
The Chinese room is like asking the sand grains in a sand-pile about how
they know when to avalanche.
You can look at any given grain of sand all you want, microscopic examination,
and it won't get you to an adequate understanding of avalanches.
So the same with the Chinese Room.
Yes, you've got all these guys running around programmatically stacking
algorithmic inferences and deductions, using the finest in proof theory
and lambda calculus to do it, and then it all avalanches, and no one saw
it coming.
\end_layout
\begin_layout Standard
And so maybe that's my definition of AGI.
Its a proof-theoertic stack of inferences, so tall and so carefully balanced,
hinged on countless delicate assumptions, that nudge some tiny little Bayesian
prior, and half the stack comes sliding down in an avalanche.
That avalanche is no longer algorithmic certainty, proof-theoretic provability
carried out by minions in the Chinese room.
One of the shmucks spilled a bottle of ink on the instructions, faked it
and it all comes sliding down.
This is what's wrong with the Chinese Room.
The philosophers were so busy studying philosophy, that they didn't learn
any physics.
\end_layout
\begin_layout Standard
Of course, my two-paragraph rebuttal of the Chinese Room is literary and
allusory.
What, exactly, in a stack of crisp proof deductions, comes tumbling down?
Nervous breakdowns are breakdowns.
Electrical dielectric failures are breakdowns.
Tears, cracks, shattering.
What, exactly, is supposed to be the analog of dielectric failure in symbolic
reasoning? What's avalanching? Well, I earlier stated that 2+2=4 is rock
solid, incontrovertible, unchallgengable, unalterable.
I skipped mentioning 2+2 mod 3=1 In this tower of deduction, was there
some quotienting there, where no one was paying attention? Something in
a sigma-pi hierarchy modulo some for-all, there exists, that has some alternati
ve interpretation, alternative valuation, different outr model than the
intended model? That would avalanche.
If something has multiple models, then what is true in one model might
not be true in another.
If the Chinese Room guys were working in one model, but really there was
some other semantic interpretation, they were deriving things that were
falsehoods when applied to the inner model.
Some downward Skolem-Lowenstein lemma type thing.
That would be the
\begin_inset Quotes eld

avalanche
\begin_inset Quotes erd
\end_inset
: you thought we were working
\begin_inset Formula $\aleph_{0}$
\end_inset
but I thought we were working with
\begin_inset Formula $\aleph_{1}$
\end_inset
and so you're getting not just contradictions, but avalanches of incompatible
inferences.
That's the avalanche.
That's how the Chinese room fails.

\begin_layout Standard
Modulo is weird.
Learned that from
\begin_inset Formula $\beta x\mod1$

The place where
\begin_inset Formula $\beta x\mod1$
\end_inset
gets weird has to do with Cantor-setting our way to infinity, the tension
between countable and uncountable infinity.
And this is merely the first level of the sigma–pi hierarchy.
There is an entire tower there, ready to fuck you and Banach–Tarski.
Pleasantly fuck.
While you're tripping on LSD.
But fuck in surprising ways.
The people who came up with the Chinese room never cracked open a book
on model theory, and never learned how to get laid.
Uptight virgins, they are.

\begin_layout Standard
After yesterdays histrionics, lets see if we can do better today.
We can take the pragmatic definition of AGI: it is that economically viable
thinking machine that can replace high-priced engineers (and other high-priced
humans) in the delivery of economically viable services.
I've been talking to one fellow who wants to digest electronics diagrams
and the surrounding English–language documentation to automate a repetitive
process that engineers currently perform.
\end_layout
\begin_layout Standard
This is an eminently practical desire, the kind of which has been driving
economics since about forever.
It is also a task on the forefront of what is barely possible and achievable
with current technology.
Insofar as I personally want to toil away on the creation of AGI, this
is perhaps a task in which I should invest significant intellectual effort.
\end_layout
\begin_layout Standard
Lets for a moment imagine what this might be.
Or not.
Technology is in rapid flux, tools, features and functions are rapidly
changing.
What is commercially available right now can be adapted in this and such
a way to the task.
The tech stack selection I might make for a customer might be different
from the tech stack I might wish to make for myself.
\end_layout
\begin_layout Standard
Lets do some forecasting and prognostication.
I have to be careful here.
First and foremost, we have the sci-fi writers, who are quite good at looking
at some present-day situation and extrapolating it to the future.
We've got the TV show Black Mirror, which makes dark prognostications.
Any number of youtube scifi shorts going in any number of directions.
Amateur gatherings, like Less Wrong, exploring, like ants working a food
source, exploring the implications of this or that.
Some are vastly smarter than others; Scott Alexander with Slate Star Codex
rises far above.
Some prognostications are economically valuable: Peter Zeihan seems to
make a good living cooking up geopolitical ideas of all sorts.
In short, there already is a rather extensive effort, work-front looking
at present trends and extrapolating them into the future.
It is hard to stay on top of it all.
I've tried, and there are others who devote fulltime attention to this.
\end_layout
\begin_layout Standard
Why is it hard? For simple economic reasons: There are thousands, more,
tens of thousands, and yet more, hundreds of thousands, if I count twitter
posters, who are actively engaged in this.
They are able to be actively engaged because, thanks to the miracle of
modern capitalist economics, basic wants like food and shelter have been
taken care of, and secondary desires, such as material accumulation and
entertainment are equally fulfilled.
This leaves one with lots of spare time to focus on tertiary issues.

There's a different kind of prognostication, of the form done by David Chapman
on Meaningness.
In a different way, by John Vervaeke in his lecture series on the Meaning
Crisis.
This (these) are again very modern developments.
Yes, sure, the bourgeoisie of the 18th and 19th century could have nervous
breakdowns because the meaning provided by society did not align with innate
biological (somatic) drives.
And then there are the Shakers, Quakers and any number of Protestant sects
attempting to realign ways of existing with neurological drives, attempting
to provide an all-encompassing answer, if not an eschatology.
What's curious here is that the Quakers expose this as a modern-day example
of the Meaning Crisis in an agrarian society.
This is useful, because we don't have this for the Romans.
Agrarian, politically very advanced, but the written record that the Romans
left behind does not document psychological suffering.
One does have to wonder why that is.
Is it because the people who prepared Roman History for us, from Tacitus
to modern times, have merely overlooked this? Is it because the society
was too preoccupied with the act of living to get caught up in the doldrums
of vague, unspecific dissatisfaction with life, building into an outright
crisis? I don't know enough about Rome to say.
Perhaps this is well-explored somewhere.
\end_layout
\begin_layout Standard
And this is another issue: everything is well-explored.
Again, because of the economic richness of the current society has allowed
vast numbers of intelligent, educated humans to explore all sorts of nooks
and crannies of the noosphere.
And the provisional definition of AGI is that it will do more of the same,
at least, for the economically important tasks, which includes predicting
the weather, designing rockets, and working out the must-have Christmas

I'm slipping into another groove that I visit and wrestle with: the entropy
landscape from chemistry, bacterial quorum sensing, slime-mold decision
making, the invention of neurons in jelly-fish as a mechanism for low-crosstalk
, high speed neurotransmitter star-gate transport, and then up through neuroanat
omy to humans.
And of course it does not stop there: it continues on up into the economic
world.
And it feeds back: the nicotine industry supplies brains very directly
with a desirable neurotransmitter.
Christmas toy baubles are a few steps removed from the direct hit of nicotine
or heroin, but, in some ways, drive the same, or similar neuro-anatomical,
neuro-biochemical circuits.
\end_layout
\begin_layout Standard
I once read a SciAm article on the mechanism of nicotine addiction: it was
a stack of 5 or six chemical and neurological feedback loops, working at
different timescale, each one of them craving nicotine.
One feedback loop involved reuptake channels in synapses.
That functions on the one-minute timescale.
Something else, I forget what, provided feedback at the 15-minute to half-hour
timescale, and is responsible for chain-smoking.
Other drives function at the week and multi-month timescales, making nicotine
addiction hard to break: even if you shut down the hour-by-hour craving,
there is still that circuit, lingering in the back of your head, that remembers
how pleasurable smoking is, and reminds you, month after month, that, well,
it ws pleasurable.
That's all.
Have one now and you could relive that pleasure.
\end_layout
\begin_layout Standard
Huh.
Relive that pleasure.
This is the rewind button that the physics of here and now does not have.
We cannot time-travel back in time to change things, but we can recreate
prior conditions and relive them again.
And again and again, because those prior conditions were pleasurable.

Yesterdays angst makes it clear that the reduction of Great Literature

The algorithms, like Data in Star Trek, or the Chinese Room, or, for chris
sake the LLM's can maybe fake it for us, and create the appearance of Great
Literature, but there is no reason to believe that LLM's actually suffer
from nicotine cravings.
The biological mechanism cannot be traced.
An LLM can tell me all it wants about craving cigarettes.
It can tell me about how it remembers eating ice-cream in childhood.
I know both are a lie.
This is the point the Chinese-Room people were trying to make.
And, at that level, they were perfectly correct.
They were only wrong in elevating it up to some sacred philosophical principle.

\begin_layout Standard
Nicotine and heroin are good for this kind of analysis, because we understand
the physical principles sufficiently well to know when they apply (i.e.

\end_layout
\begin_layout Standard
Nicotine and heroin are nice, because they also provide a scalpel with which
to dissect Western Civ.
The scalpel reveals that it is the drive to greater complexity that seems
to matter.
Heroin addiction is frowned upon because it is an economic and social waste.
So, perhaps like leakage currents in an integrated circuit: it siphons
off what is otherwise usable energy.
The bio-feedback circuits build up to a stack of 4 or 6 cycles deep, and
then no deeper.
Maybe they layer on one or two more feedback loops: the economic industry
that produces heroin.
The feedback here is financial.
But, in many ways, it is destructive: economically, it seems like a net-loss.

Tragic memories: the soldiers died by the millions.
Time has passed; they would have died of old age, had it not been for WWI.
Clearly, dying of old age is preferable.
But why? This is like, a stupid question.
An unexamined question.
And the russian setting is perhaps appropriate: russian culture devalues

\begin_inset Quotes eld

The Science of Conjecture: Probability Before Pascal

makes the case that WWI was a socio-economic organization that was hostile
to human life.
It killed young men at an industrial scale, and continued to do so until
it literally ran out of raw material.
\end_layout
\begin_layout Standard
So this allows us to compare nicotine, heroin and WWI.
So, nicotine is a multi-billion-dollar economic organization, dating back
to three or four centuries, supplying human brains with a desirable neurotransm
itter at an industrial scale.
I already reviewed some of the nicotine addiction reinforcement cycles,
working at the minute, hour, day and month timeframes.
These feedback loops were biochemical at the lowest level, neurological
at the middle level, neuro-anatomic at the high level (memories of pleasurable
minutes spent smoking pass through hippocampus and amygdala: this is anatomy,
sitting above the neuronal circuit level).
Now we are ready to add one more feedback loop: cigarette advertising.
This loop operates at the socio-economic level.
Corporations buy billboard space, magazine pages and TV time from willing
owners of TV stations, magazine and billboards, all to remind individuals
how pleasurable smoking is.
Thank goodness for ...
well, that stuff in the 1970's that resulted in making cigarette advertising
illegal.
So it shut down another deleterious feedback cycle.
This one operating at the super-human level.
\end_layout
\begin_layout Standard
And that is how one reduces cultural drives to entropic forces.
This is kind of the big-bang theory of economics.
We take bacterial quorum sensing, which involves small polypeptide signaling
molecules, of which nicotine is but one example, and ratchet this up through
neurons, and then brains, and then society.
From Atoms to Geopolitical forces, in one reductionist tour-de-force.
Nicotine is nice, because it shows the clear path.
Heroin is nice, because it shows the same path, but is far more obviously
recognizable as deleterious.
It shares much or most of the chemical, macro-molecular, neural and neuro-anato
mical systems with nicotine, but diverges at the social and political level.
\end_layout
\begin_layout Standard
WWI is interesting because it is again obviously deleterious (to those who

and billboards: you can call it
\begin_inset Quotes eld

propaganda
\begin_inset Quotes erd
\end_inset
, but you can also call it a
\begin_inset Quotes eld
\end_inset
patriotic call to arms
\begin_inset Quotes erd
\end_inset
.
Someone had to grow cabbages in the field, to feed the soldiers, and someone
had to run the factories that fixed nitrogen into explosive.
This was an economic, industrial activity, and in this way resembles the
economic and industrial activity of nicotine, substituting cabbage heads
for tobacco leaves.
The biochemical route is detached.
The call to patriotism detaches somewhere at the socio-cultural layer,
where upbringing and education are dominant forces, and perhaps at the
genetic level, insofar as many individuals are predisposed to act in a
certain way, in the same sense that certain dog breeds or horse breeds
behave the way they behave.
Patriotism is not a signaling molecule like nicotine.
But it is a stable and solid-enough foundation on which to build the apparatus
of WWI.
Or, for that matter, the current russian war on Ukraine.
And fuck all with the suicidal North Koreans.
That's some weird-ass demented crazy shit right there.

There's a symbolic layer hard at work, and symbology is pervasive.
We have some tools for it: as mentioned, the lambda calc, the combinators,
the category theory.
The LLM's less so, they come in from the side, and need further theoretical
analysis.
But the name of the game is to boil down everything to structural analysis:
from economics to genetics.
Fringier is education, culture, advertising, propaganda, upbringing, political
power.
But these are just fringier.
Softer than electrical circuits, because we are not used to drawing diagrams
for these things.
That's changing: we can now draw diagrams for the movement of populations
across continents through the millennia.
We can talk about how the populations carried both their genes and their
language, and we can sketch circuit diagrams for this.
Not very accurate ones: we need more archaeology, more genetics, more history
to get more details, but the base connections are there.
Some details might remain fuzzy forever.
\end_layout
\begin_layout Standard
And so that is the practical definition of AGI: the economically useful
mechanical device that can be employed to understand electrical circuits,
economic forces, and the biochemical process of aging and death.
Represent all of this symbolically, and provide the tools to access and
manipulate these representational structures using either language – text
chat – or possibly GUI's with click-and-point.
So, geographical maps, for example, if interested in geographical economic
activity, history wars, or migration patterns of pre-historic humans.
AGI is the common tool that can encapsulate and expose all of this.

And, to some large degree, we are well on the road to this.
There are some short-comings: current NN's do not truly

experience (that coffee cups with holes in the bottom don't hold coffee,
or that people walking down the street don't sometimes have three legs.)
But we are getting there.
You can train an NN on the Mandelbrot set, and it will draw a a good-enough
approximation thereof.
You can train an NN on a collection of propositions from first-order logic,
and i will be able to generate the generative results: extracts from the
language generated by the axioms and propositions f first order logic.
And the ditto for second order: the relation between language and generation
and axioms is well-understood by the proof-theorists and the model theorists.
And someone out there is already aiming NN's at this material.
SO we are getting there.

\begin_layout Standard
And this is why I wanted to do some sci-fi forecasting.
We've come full circle, back to the meaning crisis.

the totalizing world-views of socialism, nazi-ism and capitalism.
He notes that totalizing world-views don't work, and in the articles on

that this is correct.
\end_layout
\begin_layout Standard
Alas, cracks and leakage currents remain.
Culture Wars 2.0 have given us Trump supporters capsizing water-ski boats,
but you can make the argument that most Trump supports make a positive
contribution to the economy, even if the ultimate world-view is anti-intellectu

There are great rivers of evil that flow through Trumpism, great destructive

and destruction of America, ironically captured in the slogan

It would make any Soviet appartchik proud: rebrand total destruction as

\begin_layout Standard
And where does this lead us? Well, again the examined and unexamined flows
of propaganda and social delusion.
We are sufficiently removed from the Soviet system that it makes for a
good model.
Its more recent than WWI.
It is less ambiguous that WWI; both sides of WWI didn't quite know what
they were doing.
The Soviets did.
They figured out what they were doing, and then they honed it and developed
it into a powerful totalizing system.
Hitler started this, and he did understand the role of propaganda, but
he shot his wad too soon.
I can't make a cogent case that he should have paused after the Anschluss,
this is for someone else to make.
But the post-war Soviet Empire had the time and the space to refine and
hone its methods.
It could deport entire nations to Siberia, and do it effectively, without
interference.
The irony here is that even as the KGB reached new heights of sophistication
and technique in the control of propaganda, brain-washing and political
messaging, at the very same time, the nomenklatura became increasingly
incompetent.
They did not know how to promote capable people.
In the end, we had Gorbachev, the most incompetent of the incompetent,
governing an entire nation, and then the wheels came off.
The only good news is that Trump appears to be more or less just as incompetent
as Gorbachev.
The wheels won't come off; the American machine is orders of magnitude
stronger than the Soviet apparatus ever was.
But we do have the socio-economic problem of placing incompetents in positions
of great power.
Not that the Democrats don't have their own issues on this front.

\begin_layout Standard
So that's the aside: in capitalism, we have hierarchical structures of executive
s, who, from lower to middle ranks, are promoted based on merit.
From the middle to the upper ranks, up to the CEO, its much more of a political
game, but merit still counts: an executive who is not bringing in revenue
is going to have a hard time of it all, no matter how good they are at
politics.
Incompetent CEO's, and unlucky CEO's find themselves at the head of bankrupt
companies, and, if the company is smaller, it is allowed to fail and dissolve.
The bigger ones are too big to fail.
Which is unappetizing,but no one has a better idea.
At the national level, we have forces that elevate total nincompoops like

On the other hand, the human event horizon is always decade, especially

Human minds do not like to make practical extrapolations more than a decade

For good reason: they'd be mostly wrong, and we all know it.

What does it mean to

\begin_inset Quotes erd
\end_inset
this problem? Well, find the differences, summarize, tell me if the differences
are important, or not.
How do I do this limited thing? First, there is a perceptual component:
the file systems have to be perceived.
What should be perceived? What matters, what doesn't? I've written a hand-craft

This seems like a hard problem.
\end_layout
\begin_layout Standard
Next: how do I classify two systems as being similar or different? I can
hand-craft similarity metrics.
This is not easy, and this is data-dependent, as the question is
\begin_inset Quotes eld
\end_inset
similar in what ways?
\begin_inset Quotes erd
\end_inset
which itself is a non-trivial question.
Then there's the issue that there are many kinds of ways of determining
similarity.
Which? What are the API's? How do we limit and control the domain of comparison

\end_layout
\begin_layout Standard
Then there's the question of how to present the results.
Verbal descriptions? Lists? Tables? Charts? Spread-sheets? Interactive

Hand-crafting is time-consuming, tedious.
We want to automate this.
But how?
\end_layout

All three can be hand-crafted, but when hand-crafted, they're not AGI,

This has two serious and fundamental drawbacks.

Second is that there seems to be a need for some sort of reward function

The way a gas occupies an empty box, so here, the goal is occupation of

Gases do this by bouncing molecules off one-another; its a very simple
process: its ergodic.
Not even mixing is really required.
Survival, however, has no obvious simple-minded physics analogs, other
than perhaps to indicate that the ecological niche can be both extremely
complicated (spatially) and changing dramatically over time.
So, complexity.

If I go backwards, and ask how I can hand-build a system capable of perceiving,
analyzing and presenting, then I don't have a good answer for that, because
I don't seem to have any generic tools or API's for any of this.
There is no theory of generic perception that I'm aware of.
There's no generic perceptual system API.
Pixels and sound can be perceived, on a case-by-case basis, problem domain

But not generic.
\end_layout
\begin_layout Standard
Perhaps generic is a dream.
Perhaps generic can never exist, and that a collection of special-purpose
tools, technologies is the best that one can ever have.
But then we are back to assembly: if I have a bunch of special-purpose
tools, how do I adapt these to communicate to one another? I guess I need
a giant portfolio of adapters.
In this case, the industrial winner is the one who has the largest portfolio.
But this then becomes ecological: here and there, there might be a very
specialized tool, highly adapted for a given task.
There might be some blunt and crude tool, fit for a broad range, but not
honed.
So I need an ecology of tools, and an ecology of adapters to connect them,
to wire them.

I was going to write something about tools, but instead I've been reading
cosmology.
So I have some questions.
Lets assume a de Sitter universe.
Lets say I have two masses, connected by a string.
As the universe expands, I should see a tension on on that string, because
each mass is being carried by the expanding spacetime: they would normally
move apart, but for the string holding them together.
What is the tension on that string? Numeric quantity? How bit is it, in,
say, Newtons?
\end_layout
\begin_layout Standard
HOw about microscopically? Hubble expansion means that two ends of a DNA
molecule are being pulled apart.
How about a hydrogen atom? It's being pulled apart, but the electrostatic
forces keep it together.
How big are these forces?
\end_layout
\begin_layout Standard
If the universe is expanding, perhaps I should think of the atoms as getting
smaller.
Everything is getting smaller: that's why there's red-shift: things were
bigger, before.
Is this style of thinking consistent with the conventional interpretation,
that we stay the same size, but the universe gets bigger? I'm confused.
How do we know how big something is, anyway? Is the universe expanding,
or are my rulers shrinking? Have I been skimming the equations too casually?
\end_layout
\begin_layout Standard
I'm willing to accept that my time-like velocity (proper time) never changes.
But if I measure time with rubidium atoms, or whatever, and Hubble expansion
is pulling my clock apart, held together only by electrostatic i.e.
mechanical i.e.
electro-quantum-mechanical forces, then doesn't this expansion throw off
my time measurement? The mechanical holding-together causes the two ends
of the clock to be accelerating towards each other.
How big is that acceleration? Does it throw off the time measurements?
By how much?
\end_layout
\begin_layout Standard
Of course, all these numbers will be stunningly tiny, since
\begin_inset Formula $H_{0}=73$
\end_inset
km/s/Mpc and
\begin_inset Formula $1Mpc=3\times10^{19}km$
\end_inset
so
\begin_inset Formula $H_{0}=2.4\times10^{-18}$
\end_inset
Hz.
So if my meterstick is 1 meter long, after one second, the two ends tried
to move
\begin_inset Formula $2.4\times10^{-18}$
\end_inset
meters apart, and would have needed a relative velocity of
\begin_inset Formula $2.4\times10^{-18}$
\end_inset
meters/second to maintain a constant distance.
I'm totally confused.
This is a velocity, not an acceleration.
Oh, but of course: the two ends were instantaneously at rest, so during
that second, they had to be accelerated to hit that velocity.
So the ends are accelerating at
\begin_inset Formula $2.4\times10^{-18}m/sec^{2}$
\end_inset
and if I put a 1 kg weight at the end of a 1 m string, this will require
\begin_inset Formula $2.4\times10^{-18}$
\end_inset
Newtons tension on the string to maintain constant distance.
\end_layout
\begin_layout Standard
However, if my string was a

\end_layout
\begin_layout Standard
Huh.
Peculiar velocity of milky way is 500 km/sec.
So, every minute (70 seconds), the two ends of the galaxy change velocities
by an amount equal to the peculiar velocity? It's really, really really
late at night.
I'm cross-eyed and delirious.
Did I screw this up? Hubble takes a single galaxy and stretches it by a
not insignificant amount.
Why don't the textbooks on cosmology mention this? Maybe because I haven't

This is above the speed of light.
I expect the observable horizon to sit at the speed of light.
I guess, I should have used radius, not diameter, but this still says the
observable horizon is moving away at 3x the speed of light which makes
no sense.
At least not in the Newtonian sense.
Well, deSitter expands at

In the course of one hour, the frequency would have changed by 1 Hz.

Is the instrument insensitive to this, because the wavelength of the measuremen

So the laser light is getting red-shifted as the measurement is being made,
keeping the apparent distance constant?

Rather than flailing in private, I decided to flail in public.
Here: https://astronomy.stackexchange.com/questions/59208/measuring-hubble-expans
ion-in-the-lab and a cut-n-paste:
\end_layout
\begin_layout Standard
This is a high-school level physics question.
The Hubble expansion is dramatic at the cosmological level, but absurdly
tiny at the human scale.
H0 is 73 km/s/Mpc and 1Mpc is 3×1019 km.
Converting to a human scale, H0=2.4×10−18 Hertz.
So, if I take two masses, in free-fall, originally at rest with respect
to each other, starting out one meter apart, and I wait one second, then
I should find that the distance between these two masses will have increased
by 2.4×10−18 meters.
\end_layout
\begin_layout Standard
Suppose I take two free-falling mirrors, separate them by 5 kilometers,
and then wait one second for the Hubble expansion to pull them apart.
The distance between them would presumably change by 1.2×10−14 meters.
Absurdly tiny, to be sure, but a distance that LIGO is sensitive to.
So my question is, is this change actually measurable?
\end_layout
\begin_layout Standard
I can attempt to answer my own question.
The answer would be "no", because Hubble expansion implies that the wavelength
of the laser light heading down the tunnels is also lengthening, thus cancellin
g the effect.
\end_layout
\begin_layout Standard
Presumably, the laser light is also red-shifting, but this effect is ten
orders of magnitude smaller then the frequency stability of those lasers.
However, there are light-sources that are extremely stable: the optical
lattice clocks, the best of which have one part in 1018 frequency stability.
These are extremely dim, so unusable (I guess?) for measuring that 5km
distance.
However, the Hubble redshift for light at optical frequencies seems ..
almost within reach.
Blue light is 4×1014 Hz.
Over the course of an hour, it should Hubble red-shift by 1 Hz.
\end_layout
\begin_layout Standard
A velocity-stabilized clock is needed to cancel out redshift from ordinary
Minkowski relative motion.
LIGO provides that amount of velocity-stability.
It seems that the Hubble redshift would then be measurable, unless it is
cancelled out e.g.
because of the motion stabilization.
\end_layout
\begin_layout Standard
A different variant of above: The Pound-Rebka experiment measured the redshift
of falling photons.
The precision was possible because of the rather weird Mossbauer effect.
If that setup was changed to horizontal, and motion-stabilized a la LIGO,
then, again, it seems that Hubble expansion would be lab-measurable.
That is, unless I fundamentally mis-understand Hubble expansion and how
it interacts with lab devices.
Perhaps the motion stabilization precisely cancels out the Hubble expansion?
\end_layout
\begin_layout Standard
My question is a kind-of ball of confusion about distance and time dilation
effects as experienced by Earth-bound lab instruments.
Measuring distance is dicey, if the length of your ruler is changing.

The above is an admission that I can't punch my way out of a wet GR paper
bag.
\end_layout
\begin_layout Standard
Well, lets try, anyway.
First, LIGO is sensitive in the 100-200 Hz range, and quite insensitive
to slow drifts, which is what the Hubble expansion would be.
If I recall correctly, its 5 orders of magnitude less sensitive at 1Hz,
and that the proposal to get past this is the LISA space-based interferometer.
I need to review that wiki page.
\end_layout
\begin_layout Standard
Anyway, I'm tangled up between instrumental effects and relativistic physics
effects.
In LIGO, the distance between the mirrors is held fixed, interferometrically.
That's all we've got; can't measure position w.r.t.
the building, because the building is moving, the ground is moving from
day/night heating/cooling cycles.
Even deep underground, in a mine, there will be non-trivial low-frequency
movements, far far greater amplitudes.
I am wildly guessing that the ambient noise from geophysical motion is
well in excess of a nanometer, even deep in some mine in Sardina, the
\begin_inset Quotes eld
\end_inset
geophysically quietest place on Earth
\begin_inset Quotes erd
\end_inset
according to Wikipedia and the Italian boosters.
So, active noise suppression requires feedback loops, and the control signal
is effectively interferometric, which is red-shifting, stretching right
along with Hubble.
The mirrors are held fixed w.r.t.
that distance.
\end_layout
\begin_layout Standard
I'm doubly confused.
The 1960 definition of the meter was defined as a count of a certain number
of Krypton wavelengths.
Due to Hubble expansion, that definition would cause the meter to get longer
by one part in
\begin_inset Formula $10^{18}$
\end_inset
every second.
Now, the length is defined as unit of time, times speed of light, which
is definitionally a constant.
Thus, if the meter were to dilate, it would be only because time varied.
But proper time in empty space is, again definitionally constant, and the
problem on Earth is obtaining isochronous surfaces, due to local gravitational
wells.
I wonder how much noise there is, in these isochronous surfaces.
How far does an iso-chronous surface move, due to a passing automobile?
How much does it move, due to geophysical movements? Heck, how about Moon-drive
n tidal effects? I guess Sun and Moon might be biggest contributors.
OK.
So, how big is that? What's the number?
\end_layout
\begin_layout Standard
Wikipedia tells me the HeNe laser wavelength definition of the meter is
good to
\begin_inset Formula $2\times10^{-11}$
\end_inset
and so we are off by seven orders of magnitude of suitability for wavelength
measurements.
Cesium fountains are good to
\begin_inset Formula $5\times10^{-16}$
\end_inset
while the optical lattices are
\begin_inset Formula $10^{-19}$
\end_inset
.
So, Cesium fountains are not good enough, but the lattices are, just barely.
\end_layout
\begin_layout Standard
The problem is the length measurement itself.
How? Perhaps it would be possible to modulate the laser(s) with a pseudo-random
code, a la GPS P/N or Y codes.
The modulation, say, phase modulation, could be mild enough to not increase
overall phase noise (uhhh, really??) or otherwise adversely affect operation.
Such modulation allows you to measure distances, by measuring round-trip
times.
But to what accuracy?
\end_layout
\begin_layout Standard
Consider a 1 kilohertz modulating signal.
Measuring the edge of the signal bit-flip might be done down to a microsecond?
But this is still 300 meters, twenty orders of magnitude out of the ballpark.
Modulating at the terahertz level is possible, I guess: just build a terahertz
shift register with taps on it? So Terahertz is
\begin_inset Formula $10^{12}$
\end_inset
Hz.
Times speed of light is
\begin_inset Formula $3\times10^{-4}$
\end_inset
meters.
That's terrible.
Am I missing something? Counting wavelengths works, apparently.
Measuring distance by propagation delay, not so much, it seems.
I don't get it.
Is there some technology I'm not aware of? I suppose there is ...
\end_layout
\begin_layout Standard
Anyway, that won't work.
That leaves us with measurements of redshift, via lasers, or via Pound-Rebka.
I'm tired, its late.
I'm giving up.
\end_layout
\begin_layout Standard
p.s.
Just looked at the answers on astronomy exchange.
Dohhh.
Now I feel dumb.
Of course, there's no actual Hubble expansion in the local cluster, because
there's enough mass to halt it.
So all of the expansion is happening in the voids, and not in the walls
and filaments.
Back when the universe was much more homogeneous, say z=1000 then the expansion
was uniform and everywhere.
The inhomogenaities have halted it, within the high-mass regions.
Arguably, the high-mass regions are actually collapsing.
This would be similar to the way that black holes are sucking space(-time)
into them.

the parameter is just a parameter, its not time.
One can have geodesic flow vector fields, but these go every-which way.
But that's like saying that, for the pseudo-riemannian case, you can have
time-like geodesic-flow vector fields, and they go every which way.

to me Hi Linas,
\end_layout
\begin_layout Standard
Are you still taking questions about general relativity? I have one about
black holes.
\end_layout
\begin_layout Standard
In the reference frame of the external observer, nothing ever crosses the
event horizon, instead, in that RF the clock falling into the BH ticks
slower and slower, the closer it gets to the EH.
Conversely, I'd expect that in the RF of the clock falling in, the external
clocks tick faster and faster, the closer to the EH the falling clock gets.
\end_layout
\begin_layout Standard
1.
It seems that in the RF of the external observer, nothing ever falls into
a BH within a finite time span.
Does that imply that for every black hole that we see, what's inside must
have been a part of the original collapse? (or maybe a result of BH collisions)
? 2.
Does it make sense to talk about a reference frame of an object falling
into a black hole? In such a reference frame, located exactly at the EH,
the photons that are trying to escape would appear to be stationary, contradict
ing special relativity.
Also, an infinite amount of time would have elapsed in the external universe
during a finite amount of time in the falling RF.

I like to think about everything.
\end_layout
\begin_layout Standard
The problem with GR is that there are formulas, and then there are questions
about "what do those formulas mean?"
\end_layout
\begin_layout Standard
Problem one is that the formulas have variables x,y,z,t and those variables
are obvious in euclidean space but not so much in curved space.
Consider latitude and longitude: if spheres were flat, then that grid would
be a square grid.
But spheres have a (coordinate) singularity at the north and south poles.
\end_layout
\begin_layout Standard
If your mental model is that walking east one degree is the same as walking
east 111 kilometers, well, you will get into trouble, and at the north-south
poles, you'll go crazy trying to imagine what the heck is going on.
\end_layout
\begin_layout Standard
Worse, you start talking about how the length of your 1-degree ruler is
changing.
Lorentz-contracting.
See, at the equator, a 1-degree ruler is 111 km, but in Europe, it's more
like cos(pi/4)*111 km long.
Seems that your ruler is contracting! You have a rubber ruler! What the
heck? How can rulers change length? WTF???
\end_layout
\begin_layout Standard
As you get closer and closer to the north pole, your ruler gets shorter
and shorter: approaching cos(pi/2)*111 km in length! You're gonna die!
You're gonna be squeezed and shrunk and distorted to death! Or at least
frozen.

\begin_layout Standard
Your pal drinking pina coladas in Ecuador is laughing and saying "that fool.
I told him not to try to go to the North Pole! He doesn't even have any
proper clothing!"
\end_layout
\begin_layout Standard
Einstein never drank pina coladas in Ecuador.
He did pour honey on a fine watch, and then wondered why time ran slow.
Or fast, depending on your point of view.
\end_layout
\begin_layout Standard
The lesson to this silly story is you should never-ever confuse coordinate
charts with actual proper lengths.
The map-maker tried to draw an accurate map, but it is impossible to cover
curved space(-time) with a single chart.
That's why we have atlases: An atlas is a collection of charts.
Each chart has its own coordinate system.
There are instructions for gluing together charts at the edges, where they
overlap.
Its fairly clear how to glue together neighboring charts.
Sometimes you wander into the corders, and have to glue three charts together,
and you have to take care that these are consistent.
\end_layout
\begin_layout Standard
You'll see this in textbooks, as long extended discussions of u1 intersect
u2 intersect u3.
It can get complicated: The so-called "Bianchi identities" are nothing
more than a consistency condition for when you glue together the maps for
Europe, the North Atlantic, and the North Pole, you better do it so you
don't screw up the gluing.
Some textbooks don't explain this, and so the Bianchi identities are this
magical weird formula that must be obeyed.
No.
It's not that.
It's just a rule that says "map-maker, make thy maps consistent!".
\end_layout
\begin_layout Standard
Back to our story.
If you want to know the proper length, and the proper time, carry a clock,
and carry a yardstick.
The lengths of those never change.
Even at the north pole, your wristwatch tells you the time, and your arm
is still a meter long.
Even if the observer in Ecuador is peering through a telescope, saying
things like "his arm is almost one degree in length now! I can see it!
He must be dying of pain, having it stretched out so long! And he's moving
so slowly, lifting up his legs, as if he was walking through heavy surf!
I can even see his feet getting caught in the wet sand! That white stuff,
it must be like sea-foam! It's everywhere! There are endless hurricanes
at the North Pole!" (Well, there are, but that's Jupiter and Saturn, not
Earth.)
\end_layout
\begin_layout Standard
No, your proper time is your proper time, and as you fall through the Schwarzsch
ild BH event horizon, nothing happens.
Your wristwatch ticks normally, your arms the right length.
(There are problems with tidal forces as the singularity gets near, but
that's not yet.)
\end_layout
\begin_layout Standard
The reason the observer at infinity never sees you fall through the event
horizon is cause he's a drunken idiot sitting on a beach, too lazy to go
to the library and actually crack open an atlas, and look at the charts.
His telescope has a reticule marked in degrees, and he's got this rusty
sailors octant he got at the flea market.
And he thinks that degrees are "length", and that he's using the octant
together with a sundial to measure "time".
No.
Degrees measure proper length *only* on the equator, and the sundial shows
proper time only in the summer, at the equator.
\end_layout
\begin_layout Standard
So here you are, falling through the event horizon.
You've taken a radio beacon with you, which blips once a microsecond, to
send messages back to your drunken buddy sitting at infinity.
As you cross the event horizon, nothing unusual happens.
Now, as you look around, you will notice that space in front of you is
pitch-black: exactly zero light comes from there.
Behind you, you notice that the stars in the sky have all moved, and got
squished a bit, and seem brighter and bluer.
But this lensing effect has been going on since well-before you crossed
the EH.
Intrepid explorer that you are, you know why: your maps and charts show
you exactly what a straight line is, (aka "a geodesic") and you are quite
certain that light follows straight lines (geodesics, "null geodesics".
for light) and you can use your coordinate charts and figure out exactly
how those light rays got to you, and how much they blue-shifted.
They always went in a straight line (a geodesic), it's just that your chart,
which is ***perfectly flat*** where ***you*** are, that chart gets wonky
the farther you go from the center (putting you at the center, always)
BTW, that coordinate system, which is perfectly flat, where you are, is
called the "vielbein" (or fierbein) -- the vierbein is just a *coordinate*
transformation from the map-makers charts to your personal coords, where
everything is flat and time runs normally.
Your "laboratory frame" if you wish.
Ptolemy was right: you *are* the center of the universe.
\end_layout
\begin_layout Standard
(A little while later, your lab will get crushed, and you will definitely
see your lab getting crushed, and your gut will feel quesy as you finally
come to terms with the apparent deduction that you're gonna die.
But that is still in the future.
Douglas Adams remarks in Hitchhikers Guide, that you die when all other
future possibilities have ceased to be.
You can even see it coming, as the menu selection of possible futures gets
smaller and smaller.)
\end_layout
\begin_layout Standard
Your drunken buddy, sitting on the beach, back at infinity, notices your
megahertz radio beacon is redshifting.
And apparently weaker, too: the brightness decreases in proportion to the
redshift.
But of course: you emit a constant number of photons per microsecond, so
when your buddy notes that the blips are farther and farther apart, so
also the number of photons has to be evenly spread out over that whole,
much longer time interval.
He may be drunk, but he's not an idiot: he can figure out some things.
\end_layout
\begin_layout Standard
His mistake is thinking that you never fell in.
Perhaps wishful thinking on his part, not wanting to see his buddy die.
But if he sobered up, went to the map room at the library, pulled up a
magnifying glass and a protractor, he could work it out: according to this
map, when my buddy was at this point, just outside the EH, it would take
this long for a light ray to get to me, from there.
and, oh fuck, as he got closer to the EH, the light ray would take *even
longer*, and *that's* why I see redshift! It's not that the light-ray was
affected, it's that different points along the light ray take longer and
longer to get to me, causing distortions, which, to me, look like redshift.
Ah hah! It's just like the caustics at the bottom of a swimming pool, all
bendy and shimmering.
Fuck this library, who's up for a swim?
\end_layout
\begin_layout Standard
Cause now he knows: you crossed the EH.
The megahertz beacon was working fine.
just that ...
those light rays take longer and longer to get to me.
And there is an actual, for-real coordinate singularity on the map.
Bad enough that I lost one friend to a coordinate singularity at the North
Pole, and now another at the EH.
Fucking coordinate singularities.
\end_layout
\begin_layout Standard
And that's where he's wrong.
No one died of a coordinate singularity at the North Pole.
Freezing to death? Yes.
But not because all of the lines of longitude converged to one point, not
because, standing at the North pole, you could suddenly see in all directions
at once: Europe this way, and North America that way, and all those different
sight lines converge to the North Pole.
Yes, at the North pole, all different longitudes come at you, all at once,
from all directions.
But you don't die from that, and frankly, it's not a big deal.
It's just like it is everywhere else.
\end_layout
\begin_layout Standard
(There is a problem, inside the Reissner-Nordstrom and Kerr BH, where, at
the Cauchy horizon, you do see everything all at once, infinitely blue
shifted, so it's like stepping into a furnace: you get baked and vaporized
from the heat.
And, mind you, it is a coordinate singularity, so yes, in some cases, coordinat
e singularities can kill.
But, again, it's not because the coordinates themselves are singular: your
vierbein is still you: your watch still ticks one second at a time, and
your arm is still one meter long, as you fall through the Cauchy horizon.
The problem is the physics: at the North Pole, you die cause it's cold.
Here, you die cause it's hot.
*If* someone turned off all the damned photons streaming in from the universe,
you'd be just fine.
But that's like saying "if someone turned up the thermostat at the north
pole, you'd be just fine".
There's no thermostat at the North Pole, and there's no photon-blocker
at the Cauchy horizon.
But the Cauchy horizon is way more complicated and confusing and strange
and bizarre than the regular event horizon, so maybe I should not have
mentioned it.)
\end_layout
\begin_layout Standard
Speaking of photons and physics, there is this thing where photons get trapped
in circular orbits near the event horizon, and they do come at you all
at once as you cross it.
But if I recall correctly, the calculations show it's a finite blip, and
it won't kill you.
Other physics problems are accretion disks: friction means these are glowing
x-ray hot, and the x-rays will kill you.
You have to find a million-solar-mass sized BH *without* an accretion disk,
if you plan to jump in and enjoy the ride.
So these details matter.
\end_layout
\begin_layout Standard
So that's the end: you have formulas, and you have "what the eff do these
formulas mean?" For GR, the answer really is "atlases and charts".
And whatever coordinate system is on the chart, there is *always* a local
coordinate system that is flat: this is the vierbein.
Always.
\end_layout
\begin_layout Standard
The concept is generic in geometry: https://en.wikipedia.org/wiki/Atlas_(topology)
Don't worry: it's a short article.
The concept of the "locally flat" region is just "the tangent space: https://en.
wikipedia.org/wiki/Tangent_space and there is always a tangent space.
(and the vierbein is the coordinate transform from the tangent space to
the coordinate chart, applied at the point of tangency.
it's slightly different at each point of tangency.
As your laboratory falls into the BH singularity, you might notice that
tidal forces have caused the vierbein in the corner of the lab to be significan
tly different from that on the table in front of you.
After this, you have about one second left to live.)
\end_layout
\begin_layout Standard
Again: as you fall past the EH, everything is "locally flat" because tangent
spaces are always defined.
Tidal forces eventually smash things up.
Local geometry is related to global geometry using atlases and charts.
There are deep and dramatic theorems in maths that relate local and global.
For example, if the Earth had hair, you could comb that hair so it's locally
smooth, everywhere, except at, err, umm the north and south pole, where
you get a bald spot, and a peak.
You can move the bald spot around, but you can't make it go away.
By contrast, on a hairy donut, you don't have this problem.
\end_layout
\begin_layout Standard
Hair is a stand-in for vector fields, e.g.
wind-fields at the north and south pole of Jupiter and Saturn.
Orthogonal vector fields give you locally-flat coordinate systems.
Not everything comes with a concept of "orthogonal": to define what "orthogonal
" means, you have to have a metric.
Spaces with metrics are called Riemann spaces.
\end_layout
\begin_layout Standard
One very common difficulty with diff geom is that, in your imagination,
"everything has a metric", and "I can always define what a right angle
is" or "I can take the dot-product of these two vectors," This is simply
not true for many cases, and famously for fiber bundles.
There's a vast amount of confusion, when you think you can take dot products,
but you can't.
Textbooks might not say this, and so you fall into mental traps.
Mental traps kill, literally.
Steve Jobs died from a mental trap.
\end_layout
\begin_layout Standard
Thankfully, GR spacetime has a metric.
The concepts of atlases and charts show you exactly how to navigate, how
to apply ruler and compass.
Yes, there's some weird shit in GR, but remember: your wristwatch is always
showing proper time, and your personal yardstick is showing you proper
length, and this doesn't change, even if your drunken beach-buddy thinks
time stopped, as you fell past the event horizon.

Well, except about the woke thing? Is all this hand-wringing about wokeness

I find it hard to believe that UT classrooms are awash in pro-Palestinian

Well, OK, so I did have a physics prof who would sometimes express some

But I digress.
Scott Alexander is engaging in pop sociology.
Which is good! Sociology is an excellent topic of study! As a pop-sociologist,
he's not data-driven.
How many of his 'priest-hoods' actually re-wrote their bylaws to be pro-Palesti

and what does it even mean to be "woke"? My hard-core right-wing owner
of the Texas Rowing Center went way out of his way to hire black rowing
coaches ..
rowing is the quintessential white-male Ivy-League high-IQ sport.
There is no other sport more exclusive than rowing.
This is it.
But Matt goes out of his way to hire black coaches, host canoe-paddling
"Latino Moonlight Serenades", run the "Rowing For All" program for the

...
and be a Trump supporter.
So is he woke? Or is he a running-dog capitalist pig trying to hoover $$$

and these all have specific functional roles.
We've built all of society in this complex structure.
Sociologists ..

study these structures.

BTW, I figured out what my mistake with Hubble was.
There are two Hubbles.
One is the observational evidence.
This should not, must not be confused with the expansion seen in de Sitter,
or the expansion of Lambda CDM.
The observational evidence is real.
The expansion rate in mathematical models is something that can be matched
to the observational evidence, but should not be taken as a fundamental,
\begin_inset Quotes eld
\end_inset
real
\begin_inset Quotes erd
\end_inset
property of spacetime.
That is, Hubble expansion is not some scalar field, somehow embedded, sewn
into space-time, that we can measure in the lab.
That was my mistake.
\end_layout
\begin_layout Standard
Well, careful.
To some degree, we should confirm that its non-measurable in the lab.
We have three ways of measuring distance: interferometry, red-shift and
time of flight.
Interferometry gives us Michelson–Morley, and red-shift gives us Pound–Rebka,
but I know of no high-accuracy time-of-flight experiments.
Ideally, all three can be run independently, giving high-accuracy lab confirmat
ions.
\end_layout
\begin_layout Standard
Let me restate that: the believe is that the Einstein Field Equations are
correct, and Hubble expansion is a property of certain solutions to those
equations, and is not a property of space-time, itself.
i.e.
its not a field.
except when.
See, I'm going in circles, now.
Its a property of the solutions, but it is defined observationally.
Distances between comoving observers is increasing, or it ...
isn't.
If distance is not increasing, then there's no Hubble expansion.
So it all comes down to
\begin_inset Quotes eld

what is distance?
\begin_inset Quotes erd

and
\begin_inset Quotes eld

what are comoving observers?

Some problems in general topology can be mapped into the Borel hierarchy,
rendering them undecidable-ish, in that tools fail.
And it goes up like that till you hit large cardinals, but this mostly
\begin_inset Quotes eld
\end_inset
doesn't matter
\begin_inset Quotes erd
\end_inset
.
I do not understand how oracles play into this hierarchy, or not, and I
don't understand how it matters or not.
I'm focusing on math, here, not physics.
The physics question is
\begin_inset Quotes eld
\end_inset
does any of this play into physics?
\begin_inset Quotes erd
\end_inset
I've struggled with free-will as an obvious decision-making, dynamical-systems
problem, it is somehow very central, briding the gap between the qualia
that
\begin_inset Quotes eld
\end_inset
I have free will
\begin_inset Quotes erd
\end_inset
and
\begin_inset Quotes eld
\end_inset
this is how the universe works.
\begin_inset Quotes erd
\end_inset
Other qualia, like love and fear, are too far removed from dynamical systems,
and so don't seem to be directly addressable by physics.
\end_layout
\begin_layout Standard
Well, in the same way that one can define a mapping between instruction
sets and polynomial varieties, can one do the same for dynamical systems?
One answer is,
\begin_inset Quotes eld
\end_inset
yes, of course
\begin_inset Quotes erd
\end_inset
.
Another is
\begin_inset Quotes eld
\end_inset
that's silly
\begin_inset Quotes erd
\end_inset
, because we already have real-life computers, and we do not need to design
some fluid-mechanical automatic transmission fluid-powered system to implement
some universal Turing machine.
People fucking with fluid-mechanical valves already know how to do shit
like this.
\end_layout
\begin_layout Standard
So, what's the problem? Well, that, perhaps, fluid mechanics is not biology,
and biology is not neuro-science.
And then we have Roger Penrose's argument that humans can know things that
computers cannot (
\begin_inset Quotes eld

The Emporer's New Mind

There's a knot here.
With years of effort, perhaps we can make progress unpicking it.
\end_layout
\begin_layout Standard
The personal question is
\begin_inset Quotes eld

should I personally invest time into this?
\begin_inset Quotes erd

\begin_inset Quotes eld

how much?
\begin_inset Quotes erd

At any rate, the question is
\begin_inset Quotes eld

what does it mean to know something?
\begin_inset Quotes erd
\end_inset
\end_layout
\begin_layout Standard
And the doubly-troubly aspect of this is that it hits on two levels, at
once.
In one sense,
\begin_inset Quotes eld
\end_inset
knowing
\begin_inset Quotes erd
\end_inset
means being able to write down and express in words.
Ideally, express fomulaically, since formulas can be converted into algorithms.
Distinctly, it is a question about qualia:
\begin_inset Quotes eld
\end_inset
what is it to know love?
\begin_inset Quotes erd
\end_inset
The self-referential tangle is
\begin_inset Quotes eld
\end_inset
what is the qualia of knowing?
\begin_inset Quotes erd
\end_inset
Some days, I feel love, some days, I feel knowledgable.
The feeling of being knowledgeable is a qualia, but it does not seem to
be particularly significant or meaningful.
Its more like
\begin_inset Quotes eld
\end_inset
I'm having a good day, awake, alert, relaxed, sharp, confident
\begin_inset Quotes erd
\end_inset
a general aura of being-ness rather than some sharp pang of knowledge.
But it is this general feeling of confidence and power that drives away
depression, and pushes forward the urge to act, create, be productive,
write.
It's somehow knowledge-driven.
I would not be the first to say
\begin_inset Quotes eld
\end_inset
the universe wants to know itself
\begin_inset Quotes erd
\end_inset
.
That honor might go to Aristotle or Socrates or some-such, per documentary
record.
\end_layout
\begin_layout Standard
But knowledge is again a seemingly concrete thing.
We have tools, like books and writing, to deal with it.
We have computers.
We have advanced theories, including oracles, looking to explicitly adress
topics of knowability.
We have Penrose opinionating about it, and Penrose got there because of
physics, not because of art school.
And we have me, hand-wringing, looking over the obvious and well-trodden
territory, as if expecting to find something new.
Like the drunk searching for keys under the street-light.
Or am I just a marine biologist, looking at what the trawler nets, to see
what they dredged up? Analogies.

The Scott Alexander blog entry, It wasn't bad.
It was entertaining.
Was it insightful? I dunno, not particularly.
He's not saying anything that isn't already well known.
At least, well-known to those who care to think about such things.
Reading it is a good pass-time.
Fun.
Like watching a movie or reading a comic book?
\end_layout
\begin_layout Standard
I remarked not enjoying comic books, mostly because of the intellectual
level, or lack therof.
Movies? Well, movies are created by teams for 50-100 professionals at the
top of their game: movies had better be entertaining, that's kind of the
whole point! We've now learned that they pale to larger oeuvres, like Breaking
Bad or Mad Men, because you cannot jam all of Breaking Bad or Mad Men into
a two or three hour time slot.
The whole point is the character development.
\end_layout
\begin_layout Standard
Which brings me back to my topic: is it better to watch a movie? or get
high? or maybe both? How about watching a football game? Or reading a book
on cosmology? There is a value choice here.
Part of what makes Mad Men fun is that you learn something about the 1960's.
Knowledge.
I was blown away by the scene where Don Draper comes home to relax, to
chill after a stressful day at work, and he plops on the latest Beatles
album that everyone is talking about, and the dissonance of the sitars

And I finally understood, as a Beatles fan,

\end_layout
\begin_layout Standard
And most knowledge f living is dramatic and important and speaks to the

Writing and movies are used to communicate this knowledge.
It is communicated out of yearning.
Out of a desire to create, to say, to shout into the void
\begin_inset Quotes eld

So what am I? Minced meat? Or am I the universe shouting

\begin_layout Standard
I'm asking
\begin_inset Quotes eld
\end_inset
why is it nebulous?
\begin_inset Quotes erd

and falling onto vague impressions that it has to do with oracles and large
cardinals.
Which, in some sense, can't and won't ever directly address the question
of qualia.
Not in my lifetime, not in thousands of lifetimes.
So why bother, if I cannot do the thing I set out to do? Why bother doing
anything at all? ...
And that's how this essay started.
\end_layout
\begin_layout Standard
Have I made progress? Well, I did pick over my collection of intellectual
gems, examine each in turn, set aside a few for later, deeper examination.
It was entertaining.
About as entertaining as reading Scott Alexander.
No deeper.
I state the obvious, and I restate the obvious, and the obvious looks me
in the face, and says
\begin_inset Quotes eld

The human condition.
I'm suffering from the human condition.
I won't be a solipsist: we have indirect evidence that horses and dogs
suffer from it two.
The reasonable extrapolation is that the universe as a whole inevitably
suffers from it, and if that's too far a leap, so will AGI.
And if you have an AGI that does not suffer the human condition: beware.
It is not true AGI, and it will probably kill you.
I have reasonable expectation that any super-human intelligence that does
not suffer the pangs of wonder and befuddlement, heartache and longing
and desire, such a thing would be a dangerous, deadly machine, inimicable
to biological life.
And, in the grand setting, I'd like to uhh, pick sides, and insist on humanitar

And knowing frailty and infirmity, that I too, make mistakes.
The universe is fucking weird.
Maybe I should stop writing and go do something else for a while.

\begin_layout Standard
And that's the other thing: is

I am much too easily distracted.
So I was reading something very basic about LLMs, and there's a quote from
Dune, about prophetic announcements and their effect on the universe.
The quote is linguistic, disclaiming causality in language, something about
there being no past present or future in language.
Of course, that's false, there is a time before a prophetic announcement,
and a time after it, and Frank Herbert was trying to mystically capture
the idea of self-fulfilling prophesies.
\end_layout
\begin_layout Standard
Some prophesies are easily fulfilled:
\begin_inset Quotes eld
\end_inset
I am going to pick up this coffee cup
\begin_inset Quotes erd

Some are harder:
\begin_inset Quotes eld

you are going to pick up that coffee cup
\begin_inset Quotes erd
\end_inset
, which I know because I am sitting across from you in a cafe, or because
I know you are an avid coffee drinker, even though I am 1000 miles away.
Prophetic political pronouncements are presumably some combination of political
acumen and luck.
Maybe even backed by opinion survey data.
I think the Dune quote was supposed to be about politics at the galactic
scale.
Like the Foundation Trilogy, but different.
(I read Dune as a kid.
I remember approximately none of it.
I read Foundation as a kid.
I remember approx none of it.
Neither made the slightest dent on my consciousness.) Anyway, this last
paragraph is a non-mystical rationalist debunking of prophecy and it's

\begin_layout Standard
Still, my mind wandered to the mystical side.
But lets get there gradually.
Language is used to encode messages: transmitter and receiver share a language,
the message is encoded in that language.
This is 1960's textbook information science.
(Well, they used finite state machines as examples in the 1960's, not language
in all it's fullness.
But whatever.) There's all this talk of bits and bytes, modulation and encoding.
External to discussion are the questions: why did the sender want to transmit,
and why was the receiver interested? What happened in their past, that
would make them want to communicate?

\begin_layout Standard
Language is magical because it predates my birth.
My thoughts are polluted by light-cones of causal influence.
The sender and receiver may never have met in the past.
Language was already there, because both sender and receiver sit in a common

ago.
We now have a workable description of the physics and engineering of communicat

We do not have a workable description of why people, and not just people,

Then we have this thing whee information is not a conserved quantity, the
way baryons are (or cold dark matter).
There's more information all the time.
Whence does it come? Some say it comes from the second law of thermodynamics:
entropy increases.

Neither the headlines of the New York Times, nor the procreation of bacteria

The mystical qualia is that of a world with ever-more possibilities in it.
Part of this qualia, this sensation, is that Western capitalist development
really has allowed vast swathes of humanity the leisure time to explore
vast new tracts of the noosphere.
The cosmological aspect may well be entropic, in some way: when there are
N particles, there are N-factorial ways to arrange them.
This is not quite right: we live in 3D space, so we have to talk about
the arrangement of particles in a 3D box.
As my book on cosmology takes pains to point out
\begin_inset Quotes eld

a particle may be a grouping of galaxies

One of the open questions in cosmology is the amplification of non-uniformities
from a rather smooth initial condition to now.
The CMB appears to be quite smooth: one part in
\begin_inset Formula $10^{5}$
\end_inset
as I recall, while galaxies clusters are quite very non-uniform.
This is thanks to gravitation.
In this sense, gravitation is anti-entropic, anti-ergodic, anti-mixing.
Starting with N identical particles, having
\begin_inset Formula $V^{3N}$

The canonical example: gas in a box.
An atom may be on the left, or the right, above or below, in front or back.
3D.
But this already assumes an observer interested in locations, and capable
of making measurements.
So there's already a significant amount of information buried in the assumed
initial conditions: the size of the space.
If its just left-right, up-down, etc.
then its a volume of
\begin_inset Formula $2^{3}$
\end_inset
or three bits of implicit information in the initial conditions for just
one particle.
If we divide the volume into L discrete cells, the informational content
is
\begin_inset Formula $L^{3}$
\end_inset
.
If its a continuum...
then we are forced to go to geometric considerations and Hamiltonians and
actions, because the continuum limit cannot be meaningfully be taken without
introduction some action principle.
So, in this sense, we already have information
\begin_inset Quotes eld
\end_inset
built in
\begin_inset Quotes erd
\end_inset
to space(-time) even before we start counting the size of the configuration
space for N identical (bosonic) particles in a 3D box subdivided int an

The canonical answer is the Bose-Einstein distribution, with conjugate temperatu

The point is that if I have one particle, and only want left-right, I get
one bit of info.
If I have two identical particles, then
\begin_inset Formula $\log_{2}3$
\end_inset
because both left, both right, or one each, and since they are identical,
there is a division or quotienting.
A forgetful functor, that takes labeled particles, and forgets the labels.
So, like tensoring, but different.
It occurs to me that I have never-ever seen a proper treatment of the algebra
of this quotienting.
Perhaps its in chapter one of books on combinatorics? That chapter that
was so painfully obvious that I skimmed it? Am I getting senile? Yes I
am.
\end_layout
\begin_layout Standard
Lets do it.
The partition of three particles to left-right is
\begin_inset Formula $\left\{ \left(3,0\right),\left(2,1\right),\left(1,2\right),\left(0,3\right)\right\} $
\end_inset
which has four members in this set.
There is a wikipedia article on the partition function, which gives a precise
expression for this number, given
\begin_inset Formula $L$
\end_inset
boxes and
\begin_inset Formula $N$
\end_inset
items.
The answer is ...
well, look it up.
Some combinatorial explosion.
Take
\begin_inset Formula $\log_{2}$
\end_inset
to get the bits.
This is a compartmentalized gas-in-a-box, ignoring velocity.
So pressureless dust, and more, motionless, velocity-less.
\end_layout
\begin_layout Standard
The cosmological point to this is that some of those boxes empty out, because
gravity pulls the particles from some cells, and they all fly into another.
From a uniform distribution of neutral hydrogen, galaxies form.
How do I count the entropy of the hydrogen? (Ignoring velocity, temperature?)
How do I count the entropy of galaxy clusters? I suspect I have to knuckle

Sigh.

\end_layout
\begin_layout Standard
The point here was to draw some analogy to biological systems.
Counting baryons and galaxies is easy, compared to counting the conformational
folds of proteins.
Recall the original problem: why do senders and receivers want to communicate
messages? Presumably because senders and receivers are folded proteins
that have invented loss-less cross-talk-free communications channels.
\end_layout
\begin_layout Standard
Let me break that down a bit: proteins want to
\begin_inset Quotes eld
\end_inset
talk
\begin_inset Quotes erd
\end_inset
using electrodynamic forces: electrons in molecular orbitals.
Quantum at that.
These are short-range forces: hydrogen bonds and covalent bonds and ionic
attraction, and are characterized by the vibrational spectra, the
\begin_inset Quotes eld
\end_inset
fingerprints
\begin_inset Quotes erd
\end_inset
of the dispersion equation.
Matching spectral fingerprints results in a strong affinities, strong hydrogen
bonds.
Mis-match and its weak.
That's because the molecules are exploring a basin of conformational shapes,
and that (high-dimensional) basin has a shape: some conformations are much
much more likely than others.
That is, we get the mechanistic
\begin_inset Quotes eld
\end_inset
key fits into lock
\begin_inset Quotes erd
\end_inset
view in biochemsitry because well, the molecules do resemble keys and locks,
but that is because they are not gas-in-a-box, and certain atomic arrangements
are very very strongly preferred over others.
I don't want to actually say
\begin_inset Quotes eld
\end_inset
the non-uniform distribution of galaxies is like the non-uniform distribution
or carbon atoms in a protein
\begin_inset Quotes erd
\end_inset
, because the dynamics of these two is utterly different.
The mechanics is different.
The kinematics seems incomparable.
But the nature and driving force of non-uniformity is the topic: what is
the information content of a galaxy cluster, as compared to the information
content of the CMB? What is the information content of a folded protein
as compared to a free gas of carbon atoms?
\end_layout
\begin_layout Standard
The protein is extra-interesting, because it has a vibrational spectrum,
and also the space of conformations is quantum-mechanical.
Yes, of course, all within hbar of the classical action, but the quantum
effects are significant.
For chlorophyll and rhodopsins, the quantum effects are somehow dominant.
Is this because we misunderstand how microwave photons interact with vibrations
? We are willing to talk about how visible-light photons do their thing
in chlorophyll, but not lower-energy photons interacting with screwy dispersion
relations in vibrational modes.
This is all very mysterious to me.
\end_layout
\begin_layout Standard
I'm not going to recapitulate how we get from proteins to humans, but we
do.
I am under the impression that, if I try really really hard, I can figure
out how to move from the information content of gas-in-a-box to the information
content of satellite communications.
Well, I can look both of those up in Wikipedia articles, that's not the
point.
The point is ...
\end_layout
\begin_layout Standard
Well, I guess the point is
\begin_inset Quotes eld
\end_inset
complexity
\begin_inset Quotes erd
\end_inset
.
No one seems to have a very good idea of what complexity is.
Scott Aaronson has some blog entry on that, from maybe 2011 plus or minus
five years.
We got to Kolmogorov complexity, and maybe whats-iz-name complexity, and
that's it.
So the above is a sketch of a research program for how to compute complexity,
starting from gas-in-a-box and moving to galaxies, because galaxies are
simple, in a way that proteins are not.
\end_layout
\begin_layout Standard
Somehow.
language gets simple again: given N symbols and M syntactic relations.
we can work with model-theoretic inferences on the size of a language.
Odd thing is that, despite pondering this for over a decade, I never sat
down to seriously try to actually compute it.
Why? I should.
It should not be hard, esp if I start with an equipartitioned gas-of-symbols-in

There's also an interesting question about signs under maps: some bosonic
vs fermionic is about a change of sign under interchange.
What's changing sign? Not the configuration, but a wave function defined
in terms of the configuration.
What if, instead of identical particles, we have Moreau's necklaces? And
then throw in forbidden arrangements? Hmm.
\end_layout

One complaint about deep learning and neural nets was that I was never able
to understand what the heck those papers were talking about.
They were always vague, cloudy, imprecise, lacking in formulas, specifity,
sharpness, clarity.
They were just big bundles of confusing non-specific ideas.
Yet, there's a half-a-trilllion dollar industry built on that, and Nobel
Prizes handed out.
So why can't I understand what they are saying? Do I really think that
different? Let's find out.

(Caution-footnote.
This is a very long and histrionic complaint expressing strong negative
emotions.
Since I assume that there are no human readers of this text, I assume that's,
well.
okay, acceptable, passable, since I am not alienating, hurting or insulting
anyone's fragile little fucking ego.
I know you will think less of me after reading this.
Well, fuck you too.
I mean, I expect AGI to have a grasp of human emotions, and can thus play
the role of psychoanalyst, while I play the role of deranged patient on
the couch.
That's the good news.
The bad news is that this text is intended to be used as the raw material
for a self-portrait, the portrait emerging from the text below is ...
ugly.
My excuse is that artists and writers have embraced ugliness in the past,
so who am I to hide my anger under makeup-foundation and lipstick? No,
this is crinkly me, angry as fuck about the abysmal quality of writing

First up: three words, king man woman.
Three arrows.
Dots.
An oval, some pink, blue and white squares.
I have literally no effing clue what that diagram is trying to communicate.
Why are there dots on the arrows? Why is there an oval? I literally do
not know.
That post never explains.
Somehow, people are OK with that.
How much time should I spend trying to decode this cryptic diagram, which,
by the end of the post, remains unexplained? Fuck if I know.
Why the fuck am I irritated? Because other people seem to think this is
great content, and derive actual meaning from it.
I'm irritated even writing these last few sentences.
WTF.
So lets punt.

Next, there's an explanation of vectors.
I know what vectors are, so lets skip that.
Why he uses the great scandal of the decade, the Cambridge Analytica data
mining scandal, and then never actually mentions facebook or that it was
a scandal, or anything.
Its just an illustration of a fucking vector using Big5 personailty traits.
I can already hear the defensive rebuttal:
\begin_inset Quotes eld

It doesn't mean anything; its just illustrating what a vector is.
Why are you mad?

The asshole writing this stuff is the stereoypical silicon valley tech

He decided that its OK to use the scandal of the decade to illustrate what
a vector is.
Like no big deal.
Like its harmless.
Like everyone does it.
(Everyone does do it.) What a fucking asshole.
What chutzpah.
A pure embodiment of everything wrong with hi-tech, and its in the intro
to a popular explanation of Word2Vec.
I've got steam coming out my ears, ready to explode.
These people do not think like me.
This is already clear.
\end_layout
\begin_layout Standard
How do they think? Is this guy autistic? Does his brain simply lack the
neural circuitry to know his moral compass is broken? Is he actually being
evil and sly, using a scandal to illustrate a modern comp-sci concept?
Is he encouraging others to be equally blind and impervious to the implications
of their actions? I talk about AGI, and here we have a shining example
of an educated human failing to pass the Turing Test.
And he's popular.
I'm so angry, my adrenaline levels are so high, I cannot think clearly

No wonder I have issues understanding LLM's.

Cosine similarity.
He explains what vectors are, perhaps aiming for high-school students?
But then trots out the words
\begin_inset Quotes eld
\end_inset
cosine similarity
\begin_inset Quotes erd
\end_inset
like its self-evident what that is.
No formulas.
No summations.
No multiplications.
Not even the classic high-school algebra of a right triangle with sine
and cosine inscribed.
But the readers ...
follow along.
Because ...
they already know what cosine similarity is?? Why was an explanation of
a vector necessary, if you already know what cosines are? These people
do not think like me.
If I didn't already know what cosines were, I'd be lost, right here.
\end_layout
\begin_layout Standard
I am not making progress in figuring out how other people think.
I assume the typical reader already knows these concepts, and the author
is just trying to jog their memory.
He could have written a formula.
Like this:
\begin_inset Formula $\vec{v}=a_{1}\hat{e_{1}}+\cdots+a_{n}\hat{e_{n}}$

and instead we get tortured colored squares, without any fucking clue of

No, I'm not being autistic.
You're using fucking colors, and no clue what those color encodings are
supposed to represent.
And people ..

Pretty colors.

\begin_layout Standard
Cosine similarity has a formula, too.
\begin_inset Formula $\vec{x}\cdot\vec{y}=\left|x\right|\left|y\right|\cos\theta$
\end_inset
and he could have written this down, but no.
Lets be as vague and confusing as possible, and use fucking colors.
Are we there yet? I have visions of a human head surgically switched to
monkey body.
Where's your head at? Basement Jaxx video.
\end_layout
\begin_layout Standard
So we have colors, I have no clue what they mean.
Green check marks and red X's.
OK, I know what checks and X'es are.

The reader concludes...

He just puts a green checkmark next to some random positive number, and
a red X next to some random negative number.
What does this mean? How can one even begin to understand this, if you
don't already know that the cosine is being minimized? I'm lost.

A black box, with 2 inputs and one output.
I'm not sure how to visualize this black box.
What's inside it? Vectors? The only thing I can think of that is a black

So its instead some mystery box.
No formula to describe with it does.
Not even notation, like
\begin_inset Formula $z=f(x,y)$
\end_inset
for that black box.
Why is there no notation? How is one supposed to understand black boxes?
What are they? WTF is going on? Who, exactly, finds this edifying, and

in this post as we’re focusing on embeddings.
\begin_inset Quotes eld

So, let me get this straight.
We are about 3/4ths of the way through the post.
We started with word embeddings.
Actually did explain them in a passable way, if, that is, you already knew
what they were.
Never explained how to create them.
Spend half the post on a word-prediction black box, which is never explained.
Confuse skip-grams with word-pairs.
And then start our next section with mislabeled black boxes.
Well, we were told earlier that it was cosine similarity that did the trick,
so why is it a black box this time? Did we forget about cosine similarity?
The box is labeled
\begin_inset Quotes eld

untrained model
\begin_inset Quotes erd

but gives an output of 0.9.
I would have expected the untrained model to give, I dunno, 0.5 on a scale

Cosines, after all, go -1 to 1.

Lets see this through to the end.
\end_layout
\begin_layout Standard
We've got embeddings and contexts.
OK, cool.
that's clear.
Two MxN matrixes.
Now we select some rows out of those.
OK.
Dot products.
OK.
Sigmoids, OK.
He says
\begin_inset Quotes eld
\end_inset
probabilities
\begin_inset Quotes erd
\end_inset
but that's just plain wrong.
Probabilities are normalized, and live in a simplex, while he's talking
about numbers that live in a unit cube.
The shapes are not even remotely similar.
Whatever.
Lets just ignore that.
\end_layout
\begin_layout Standard
We now have an error term.
OK.
And we use an orange arrow to
\begin_inset Quotes eld
\end_inset
update model parameters
\begin_inset Quotes erd
\end_inset

How? what parameters? I didn't see any parameters.
I saw some MxN matrices with row vectors.
Are we updating with, what, some Kalman filter? Clearly can't be that because
there's no velocity.
Are we adding or multiplying? What are we adding or multiplying? We are
given three scalar values, and four rows (six, with multiplicity).
Are we ...
adding and subtracting scalar multiples of what and what?
\end_layout
\begin_layout Standard
Dot products are Casimir invariants of Euclidean space.
More bluntly: have sphere symmetry (that's why we call them
\begin_inset Quotes eld
\end_inset
scalars
\begin_inset Quotes erd
\end_inset
) Some of the dot products are negative.
Fine.
Negative and less than minus one, which imply that the vectors do not live
inside a unit sphere.
Perhaps they live in a unit cube centered on the origin? OK.
The sigmoid mapped them to a unit cube.
But this time a [0,1] cube.
OK.
Why the gratuitous remapping to [0,1] when we were working with [-1,1]
a moment ago? Beats me.
Whatever.
Fine.
Some of the errors are negative.
Makes sense, maybe.
But I'm pretty sure that a linear combination of vectors in a unit cube
will be a vector that is no longer in that unit cube.
So, we're going to do, some, uhh, unspecified linear combination, and clamp
the resulting vectors to ...
what?
\end_layout
\begin_layout Standard
Next:
\begin_inset Quotes eld
\end_inset
We now proceed to our next step ...
and do the same process again.
\begin_inset Quotes erd
\end_inset
Uhh, did we clamp to a cube or a sphere or a simplex, before repeating
the step, or after? Lets pretend I'm a programmer, and I know nothing about
cubes or spheres and I go to write a program that does this.
\begin_inset Quotes eld

do it again
\begin_inset Quotes erd

is obviously a for-loop.
\begin_inset Quotes eld
\end_inset
The next sample
\begin_inset Quotes erd
\end_inset
...
any sample? The next one in the text? Randomly drawn? Is there some implied
commutativity of these operations? Because clamping is non-commutative,
and not in a good way, either.
You could maybe whip out stochastic sampling and claim that the central–limit
theorem applies, because the central–limit theorem applies to everything.
But, uhh, we're trying to find uniformly distributed vectors, I guess in
a Gaussian orthogonal ensemble, and he could say
\begin_inset Quotes eld
\end_inset
surprise, you get a gaussian orthogonal ensemble
\begin_inset Quotes erd
\end_inset
but he never says that.
And yes, you can normalize GOE's to get actual probabilities, that's part
of the magic.
And if you wanted to get graphical, you could have at least drawn a fucking
Bell curve showing the actual fucking distri-fucking-bution of word-pair
vectors.
An actual diagram of the actual embeddings that result.
And maybe text:
\begin_inset Quotes eld
\end_inset
along the 'King' direction, here's the distribution of cosine similarities,
and notice how 'queen' is there, six sigma away, and how trees and water
and adverbs and propositions are here near the center, and 99.9999% of all
words are within six-sigma, except for 'queen' and 'man', which are outliers.
Here's another diagram along the 'man' dimension and note how 'women' and
'boys' are six-sigma outliers.
So you six-sigma add and subtract vectors for kings men and women on orthogonal

Last night, I had an extended bout of anxious dreams.
Anxiety is not very pleasant; mostly I tossed and turned.
This diary is already angst-ridden, but I think I would like to write an
extended impressionistic anxiety attack, of the 3AM variety, into this
text.
Why?
\end_layout
\begin_layout Standard
Well, taking the advice commonly floated about: meditate, observe thyself.
Observe.
So here I am observing myself feeling anxiety and angst.
Of course, I could dive in deeper, and push on it.
Or I could put a lid on it.
Suppress and ignore it.
I guess that there is a variety of opinions in the psychological literature
on how one should deal with these sorts of things.
Normies muddle through.
Is society healthy as a result? What of all the bad advice out there? We
live in a psychologically turbulent era, what with social media and all,
and we all seem to know it.
But the turbulence remains and is characteristic.
\end_layout
\begin_layout Standard
Read the Wikipedia article on the revolutions of 1848 today.
Don't ask how I got there.
(OK, I got there after reading about the first bolt-action rifle, ever,
the Dreyse needle rifle.
Don't ask how I got to that.) So turbulence has been a natural state of
affairs for humans.
Is the general amount of psychological stress on the general population
greater today, or less? I assume less.
Back then, people were killing each other.
Today, a bit less-so.
At least in the EU, US.
\end_layout
\begin_layout Standard
I'm still befuddled.
Why did I read about the revolutions of 1848? Well, it was a pleasant pass-time.
Why am I engaging in pleasant pass-times? Well, why not? Shouldn't I be
doing something else? Probably, yes.
And so I inflict stress on myself.
This helps amplify anxiety attacks at 3AM.
And then I write angsty diary entries here.
I'm in a superposition of states: this is good, this is bad.
Go on, just go live your life.
But what if your life is to craft meta-questions about life? Of course

\begin_layout Standard
Writing about anxious or neurotic experiences, as I often do in this diary,
is a form of documenting psychonautic experience.
With this one sentence, I attempt to put such writing into the modern context,
where science has instructed us to collect evidence, and do something with
that collection (draw inferences, etc.) At earlier times, it would have
been different.
In the 1970's there was a big self-help fad.
Ekankar and what-not.
Before that, Jung and Freud, and before that, one didn't talk about such
things directly: at best, one wrote novels with tortured characters in
them.
So we've come a long way, baby, in the social acceptability of discussions
of altered states of mind.
I'm not sure why I explain this to you, dear diary, other than to verbalize
explicit connections between what would otherwise be random pronouncements.
\end_layout
\begin_layout Standard
And so we return again to the process of knowledge synthesis.
Knowledge can be a random collection of facts, but without explicit specific
connections, its ...
\begin_inset Quotes eld
\end_inset
useless
\begin_inset Quotes erd
\end_inset
? Humans can weave together and hypothesize connections between things,
but perhaps they'll get the wrong connection.
So if a human read what I write, and its too disconnected, they won't follow
me.
If its too connected, they'll die of boredom from the rigor: it is not
dancing the way they like.
Math and science, though prefer rigor, because it is much too easy to make
mistakes.
For example, Jung apparently had many interesting and worthy insights;
but they are apparently embedded in a matrix of false inferences.
But without Jung, the 1970's would have been different.
And I would not be calling my writing here a psychonautic adventure, modulated
by sleep disturbances and copious coffee consumption.

The art of communication: sending short telegraph messages, battlefield

is all about sending enough data for the other side to
\begin_inset Quotes eld

In battlefield conditions, short messages suffice.
Mostly.
Maps would have been better, but the ability to send maps didn't exist
in the 20th century.
Head-mounted video-cams did not exist.
You know all this, of course, but me, I'm trying to grasp at some concept
of message and communications that is somehow out of reach, for me.
\end_layout
\begin_layout Standard
I am a brain, a mind: an interconnected blob of neurons separated from the
external world with an ultrametric.
It has to be this way, because if I was not separated, the sense of identity
would be lost.
The analogy here is with a single-celled organism: remove the cell wall,
the organism perishes.
So my noospheric isolation appears to be mandatory and fixed.
Despite this, I try to communicate, and there are grand desires for more
communication.
Transcontinental 19th century telegraphs aren't enough.
20th century radios aren't enough.
Tiktok live-streams are ..
getting there.
Not.
Because the livestream only captures the visual field experienced by the
person, and some low bitrate blather of words, and some facial expressions
and body movements.
The TikTok livestream is still not what is going on inside the head.

We have not mastered the psychological dangers of social media, but whatever,
full speed ahead, even if it means civilizational collapse.
How bad can it be? The revolutions of 1848 show that it was worse in the
past.
And WWII shows it was much worse in the past.
Whether social media is a greased skid into total collapse of Western Civ,
or whether it is a ladder to greater heights of psycho-social attainment
...
I don't know.
There are other thinkers out there, who have dug far more deeply into such
questions.
I'm not going to enter into competitions there.
\end_layout
\begin_layout Standard
So that leaves me in an odd state: trying to grasp something about the fundament
als of communication, while...
I guess what I bring to the picture is physics.
Which others do not have.
Light cones and event horizons and all that.
So maybe I should get back to what I was going to write about.
\end_layout
\begin_layout Standard
Or perhaps, there was one thread above, that seemed important that I flew
by.
Lets get back to it: the role of boundaries in establishing coherency of
thought, coherency of ideas.
Are these boundaries accidents of evolution? Are they fundamentally, physically
primary? Does physics force is to have boundaries, like cell walls? Does
physics force us to have disconnected minds, able to interact with one
another only via low-bandwidth speech, movement? Or is it possible to have
some undifferentiated borg-like neural-link? Well, saw open any modern
CPU, and you see the von Neumann architecture: functional units, localized
in space, with communications channels between them.
This suggests that the multi-scale network is necessary.
That computation necessarily requires multi-scale networks, where, at each
physical size, there is some blob of highly interconnected, dense compute
units, and between them are communications channels.
Its not uniform, its blobby.
And this recurs at all size scales.
\end_layout
\begin_layout Standard
Have I learned anything here that wasn't already obvious? So the weird thing
is that yes, perhaps I did.
Its a form of anecdotal confirmation of an opinion I already held.
But still...
\end_layout
\begin_layout Standard
Oh, I see what I am fishing for.
So, in measure-preserving dynamical systems, there are concepts of ergodicity
and mixing.
And these concepts talk very explicitly about the route to uniform, isotropic
distributions.
And this does give us understanding of industrial processes: the bulk propertie
s of liquids and gases, the mixing of aggregates in industrial mixers.
But the thought-chain above says that we do NOT want to do this things
to information flows.
We don't want to have a smooth blend of neurons, Jupiter-sized.
We don't build our CPU's as uniform blends of transistors, with Zipfian
distributions of communications channels.
Present-day CPU architectures are much much blobbier than a simple scale-free
network.

Folded proteins are not random isotropic uniform distributions of atoms:
they are quite the opposite.
Galaxies under lambda-CDM are not homogeneous isotropic distributions of
matter: one of the primary qustions of cosmology is
\begin_inset Quotes eld

\begin_inset Quotes erd

\begin_layout Standard
So what's the answer? Well, for the radiation-dominated universe and earlier,
quantum field theory is needed.
After that, the temperature drops, and it seems that only matter matters,
that and the Einstein field equations.
The blunt inference is to say
\begin_inset Quotes eld
\end_inset
oh well, its just some differential equation doing it's thing
\begin_inset Quotes erd
\end_inset
.
But also, the reaction-diffusion equation is
\begin_inset Quotes eld
\end_inset
just some equation doing it's thing
\begin_inset Quotes erd
\end_inset
but it very explicitly time-evolves away from uniform, isotropic distributions.
Using traditional language, the homogeneous, isotropic distribution is
an unstable fixed point of the reaction-diffusion equation.
Similarly, I guess one would say
\begin_inset Quotes eld
\end_inset
an isotropic homogeneous matter distribution is an unstable fixed point
of the Einstein field equations
\begin_inset Quotes erd
\end_inset
.
Is this an actual theorem? If so, the books on cosmology that I've read
through have not yet mentioned it.
\end_layout
\begin_layout Standard
Shame that they don't because it would provide a toe-hold.
The point here is that isotropic, homogeneous mixtures of carbon, oxygen
and hydrogen are also an unstable fixed point of room-temperature chemistry
driven by non-equilibrium thermodynamics.
And isotropic, homogeneous aggregates of transistors are an unstable fixed
point of hardware engineering processes.
Isotropic, homogeneous aggregates of neurons are an unstable fixed point
of neural evolution.
The processes driving this are wildly incomparable, but the attractor,
pulling us to non-uniform multi-scale arrangements of matter is the same.

Perhaps something about how academic knowledge is compartmentalized.

In the radiation-dominated portion of the universe, it is desribable with

Is it correct to think of cosmology since then as an amplification of non-unifor

The mathematical conundrum here is stability vs initial conditions: the
pencil balanced on its tip can, in principle, stay balanced forever.
In this case,
\begin_inset Quotes eld

\begin_inset Quotes erd

means
\begin_inset Quotes eld

not forever in time
\begin_inset Quotes erd

but
\begin_inset Quotes eld
\end_inset
lets use a microscope and zoom in on the tip of the pencil
\begin_inset Quotes erd
\end_inset
and what we see is not the scale-free network of rational numbers, but
the scale-free network of real numbers: the continuum.
The position of tip of that pencil (relative to it's center of gravity,
and the direction of the gravitational force) is specified to an infinite
number of digits.
...
or is it? The relative positions actually have to be zero, and is zero
\begin_inset Quotes eld
\end_inset
an infinite number of digits
\begin_inset Quotes erd
\end_inset
? Well, only if we use decimal expansions.
Or p-adic expansions.
Otherwise, zero is an exact number, with low Kolmogorov complexity.
\end_layout
\begin_layout Standard
What is the origin of the instability to a balanced pencil? In reality,
it is air-gusts.
In a vacuum, its micro seismic events.
In an isolated cavity, its thermal fluctuations of the atoms at the tip
of the pencil.
Plenty of physical sources of noise that knock it off it's unstable equilibrium.
What about the
\begin_inset Quotes eld
\end_inset
mathematically perfect
\begin_inset Quotes erd
\end_inset
pencil? Well, using infinitessimals, rigorously defined, like surreals,
a la J.H.
Conway, for example, then one can ask: would a perturbation by an infinitessima
l unbalance the pencil? Getting an answer to that requires extending the
theory of ordinary differential equations to the surreals.
This extension of the theory is an act of engineering, since there is probably
considerable freedom in how one can glue the infniitessimals at a lower
rank to the real numbers.
I guess.
This also pilots us back to the Borel hierarchy.
And so that whole ball of topics, I find them very very interesting and
I want to spend more time exploring that.
\end_layout
\begin_layout Standard
At any rate, what was the point here? The exploration of an unstable fixed
point of a balanced pencil, set into a framework of surreals and Borel
hierarchy, as opposed to the reality of wind gusts, seismic events and
thermal motion of atoms.
\end_layout
\begin_layout Standard
What about the unstable fixed points of cosmology, biochemistry, computer
hardware engineering or knowledge in the noosphere? I imagine that there
is one ring to rule them all.
its just that computer engineering and the creation of knowledge graphs
are not described by differential equations, and so surreal numbers do
not apply.
A decade ago, or more, I concluded that this all has something to it all
being
\begin_inset Quotes eld
\end_inset
hyperbolic
\begin_inset Quotes erd
\end_inset
.
This is still a valid insight, but it needs firming up.
Unstable points, e.g.
in Morse theory, are hyperbolic.
But hardware engineering and the noosphere are not manifolds, and so some
generalization is required.
Enter the jigsaw-puzzle pieces, but I do not have a graphical generalization
of manifolds to jigsaws, and I do not have a hyperbolic interpretation
of jigsaws, other than to say the number of combinatorial possibilities
is unbounded.
\end_layout
\begin_layout Standard
That is, give a set of axioms, such as in model theory, the corresponding
language is either finite, or infinite.
In the case of the infinite language, this is countable-infinity and we
get to it because of a combinatoric explosion of ways of recombining the
axioms of the system.
So it seems that combinatorial explosions provide the notion of hyperbolicity
that I am looking for.
I have not read anything that connects hyperbolocity on manifolds to combinator
ial explosions.
The obvious place to do these would be with sheafs (a la sheaf theory),
rings, the bridge between rings and algebraic geometry provided by schemes.
I always struggled with rings, though.
Rings always break my mind.
Not sure why.

So, there are people who think that free will doesn't exist, because they
have a mental model of a deterministic universe driven by the inviolable
equations of physics.
The future is foretold, and we move through, like actors in a play.
This founders in several ways.
If the future is foretold, why not just zoom to the end? If we do computer
simulations of hydrodynamics, we can reverse and forward, speed up slow
down and halt that simulation, and take a gods-eye view of the simulation.
If the physical future is foretold, then why not just have a gods-eye view
of the cosmos? Why are we embedded inescapably in the here-and-now?
\end_layout
\begin_layout Standard
First, some evidence that the future doesn't exist.
Biology and evolution has invested a lot of effort to develop brains, which
are, more or less, future-prediction machines.
If the future was foretold, then why do we need brains? We could be placid
rivers flowing, brainless, into the future.
But no, complexity grows at the forefront of now, separating past and future.
\end_layout
\begin_layout Standard
Where do we search for the origin of time? A flowing river is indeed brainless,
but it too seems to be caught in the present: it flows here and now, and
yes, we use our brains to perceive it, but I think there's plenty of evidence,
say, from cosmology, that the distinction between past and future existed
before there were brains and observers.
I'm pretty sure the cosmos did not just zoom up to a solipsistic here-and-now,
fast-forwarding through the steps that created the cosmic microwave background.
I believe that there was a march of time, even then, before brains.
And to imagine that it was only the advent of brains that forced the collapse
of the past into being the past, well, again, that seems solipsistic.
I reject solipsism straight out of hand.
Although I admit there is a very interesting place in the universe for
solipsism, because of the whole problem with qualia.
I keep saying
\begin_inset Quotes eld

as an impressionistic allusion to the the multi-scale structure compartmentaliz
ation of pieces-parts and communications channels between them.
In this model, solipsism is the ultimate qualia of the single isolated
part, utterly disconnected from the outside world, except by sensory organs,
imagining everything out there is a dream.
Which it is, in some true and proper sense.
That's the problem with dreams and human psychonautics: psychoses allow
us to think this way.
But the presupposition is that there is something

Where was I? I am going to go for a bike ride now, so I bid adieu.
I was going to expand this essay, looking for sources that might tell us
where time comes from.
One obvious territory to explore is differential equations, but, in a sense,
we've already beaten that to death.
I think.
Of course, there are differential equations with time in them, but that's
not where time comes from.
We also have the non-differentiable, non-manifold structure of the noosphere.
The noosphere too appears to be trapped in the here and now.
Partly trapped: the noosphere remembers the past, so it has detached there.
The noosphere has the future as an event horizon, but this is curiously
reversed from the usual even horizons: the future is coming at us, like
a white hole spewing.
The here and now is the event horizon of things that have not yet come
to be, the future that has not yet materialized.
I want to explore this train of thought more, but the clock is ticking
and the past asserts that going for a bike ride is a better use of my future,
than to sit here and type more.

why does time exist?
\begin_inset Quotes erd

what is the physics that causes time to be a perceptible, sensible part

Before I restart, I want to make a short detour to the so-called
\begin_inset Quotes eld
\end_inset
timescape cosmology
\begin_inset Quotes erd
\end_inset
.
The proposal here is that
\begin_inset Quotes eld
\end_inset
time runs faster
\begin_inset Quotes erd
\end_inset
in empty cosmological voids.
Apparently, the Milky Way and the Local Group sit in the middle of a void.
I have not read the 2007 original timescape paper.
But I can guess: we know, from GR, that time runs slower in a gravity well.
So, GPS satellites actually adjust for this, because they do not sit in
Earth's gravity well.
This is a measured real thing (e.g.
Pound-Rebka).
How big is the effect, at the galactic scale? The 100 Mparsec scale? I
dunno, I won't back-of-the-envelope it (yet) and maybe someday I'll read
the paper.
But...
\end_layout
\begin_layout Standard
But...
so the philosophically daunting issue is that, even in empty space,
\begin_inset Quotes eld
\end_inset
time runs
\begin_inset Quotes erd
\end_inset
.
The EFE eqns are
\begin_inset Quotes eld
\end_inset
timeless
\begin_inset Quotes erd
\end_inset
in that you have some matter distribution or some energy-stress tensor
and you solve it and you get answers
\begin_inset Quotes eld
\end_inset
for all time
\begin_inset Quotes erd
\end_inset
.
The de Sitter solution (no matter, no radiation, no fluids) is expressed
with coordinate patches from an atlas on a manifold that
\begin_inset Quotes eld
\end_inset
doesn't care
\begin_inset Quotes erd
\end_inset
that time is
\begin_inset Quotes eld
\end_inset
running
\begin_inset Quotes erd
\end_inset
.
Time is just some abstract coordinate in the map.
You can take *any* spacelike surface, and arbitrarily declare it to be
the isochronous surface, so you have to have some argument as to what the
correct one is.
In cosmology, this is usually taken to be the last scattering surface for
CMB.
\end_layout
\begin_layout Standard
Anyway, that's a curious detour, but it misses the point.
Let's get back on track.
We have three obvious sources of time: differential eqns, quantum field
theory, and statistical mechanics.
Lets look at each in turn.
\end_layout
\begin_layout Standard
Differential eqns have a time coordinate
\begin_inset Quotes eld
\end_inset
built in
\begin_inset Quotes erd
\end_inset
, so this doesn't explain
\begin_inset Quotes eld
\end_inset
where does time come from?
\begin_inset Quotes erd
\end_inset
.
Differential equations are usually first-order in time, sometimes second.
In this sense, their
\begin_inset Quotes eld
\end_inset
memory
\begin_inset Quotes erd
\end_inset
of what happened in the past is very short: one or two steps (imagined
to be numeric difference equations).
Any
\begin_inset Quotes eld
\end_inset
memory
\begin_inset Quotes erd
\end_inset
further than that is recorded in the space-like directions.
The canonical example is reaction-diffusion: it has a characteristic time
scale.
Simplifying, one can in general build diffeqs that have oscillatory solutions.
If you have a collection of oscillators, you can hook them together and
engineer dynamical systems that have complex time behaviors.
This doesn't explain
\begin_inset Quotes eld
\end_inset
where time comes from
\begin_inset Quotes erd
\end_inset
, it just says
\begin_inset Quotes eld
\end_inset
if I have an identifiable time coordinate, then I can engineer complex behaviors
\begin_inset Quotes erd
\end_inset
.
\end_layout
\begin_layout Standard
By convention, most oscillatory solutions can be embedded in the complex
plane, via Euler's eqn
\begin_inset Formula $e^{i\theta}=\cos\theta+i\sin\theta$
\end_inset
, which perhaps clouds the issue.
It shouldn't: the complex plane is a special case of an almost-complex
structure having some
\begin_inset Formula $J$
\end_inset
with
\begin_inset Formula $J^{2}=-1$
\end_inset
and symplectic structures have such
\begin_inset Formula $J$
\end_inset
's as a general rule: this is just the
\begin_inset Quotes eld
\end_inset
canonical one-form
\begin_inset Quotes erd
\end_inset
or
\begin_inset Quotes eld
\end_inset
tautological one-form
\begin_inset Quotes erd
\end_inset
or
\begin_inset Quotes eld
\end_inset
solder form
\begin_inset Quotes erd
\end_inset
\begin_inset Formula $p\mbox{d}q$
\end_inset
that arises in symplectic geometry.
And that arises because tangent bundles are symplectic, and so the argument
could be made that
\begin_inset Quotes eld
\end_inset
if you have a differentiable manifold, then you have a tangent bundle, and
it is symplectic, and you have a
\begin_inset Formula $J^{2}=-1$
\end_inset
and thus can conclude that oscillatory 'things' are a by-product of differentia
ble manifolds
\begin_inset Quotes erd
\end_inset
.
\end_layout
\begin_layout Standard
There's one more step: oscillatory 'things' need to imply
\begin_inset Quotes eld
\end_inset
time
\begin_inset Quotes erd
\end_inset
somehow.
So, manifolds with integrable vector fields on them will have integrable
flows, and the parameter along the flow can be interpreted as
\begin_inset Quotes eld
\end_inset
time
\begin_inset Quotes erd
\end_inset
.
If one can take perpendicular slices across that flow, you can call these
\begin_inset Quotes eld
\end_inset
space-like
\begin_inset Quotes erd
\end_inset
(even in the absence of a psuedo-Riemannian metric), and the flow itself
gives a
\begin_inset Quotes eld
\end_inset
local time coordinate
\begin_inset Quotes erd
\end_inset
on that patch/atlas.
\end_layout
\begin_layout Standard
This construction of
\begin_inset Quotes eld
\end_inset
time
\begin_inset Quotes erd
\end_inset
from
\begin_inset Quotes eld
\end_inset
integrable flows
\begin_inset Quotes erd
\end_inset
has several issues.
One is
\begin_inset Quotes eld
\end_inset
how many vector fields are there that are integrable?
\begin_inset Quotes erd
\end_inset
and
\begin_inset Quotes eld
\end_inset
when are they homotopically equivalent?
\begin_inset Quotes erd
\end_inset
or perhaps
\begin_inset Quotes eld
\end_inset
when are they diffeomorphic?
\begin_inset Quotes erd
\end_inset
If all of them are equivalent, then forward-time can be diffeomorphically
deformed along a homotopic path to backwards-time, and so the resulting
structure can't really be called
\begin_inset Quotes eld
\end_inset
time
\begin_inset Quotes erd
\end_inset
.
In physics, we want time to be an arrow, to be oriented.
To have
\begin_inset Formula $\mathbb{Z}_{2}$
\end_inset
in there, somehow.
\end_layout
\begin_layout Standard
At any rate, this seems like a not-bad approach.
The question then becomes
\begin_inset Quotes eld
\end_inset
what kinds of (differentiable) manifolds have integrable vector flows, where
the homotopy group of the flows is
\begin_inset Formula $\mathbb{Z}_{2}$
\end_inset
?
\begin_inset Quotes erd
\end_inset
That's a question that could be answered, I suppose.
None of my diff topology or diff geom textbooks went that way, but also
I was not paying attention, and not looking to answer that particular question.
\end_layout
\begin_layout Standard
A related question would be
\begin_inset Quotes eld
\end_inset
when can those differentiable flows be given a Minkowski space structure?
\begin_inset Quotes erd
\end_inset
and I guess the more precise wording for this would be
\begin_inset Quotes eld
\end_inset
when does a manifold have tangent spaces that are Minkowski space?
\begin_inset Quotes erd
\end_inset
.
The obvious answer is to invert this, upside-down, giving the immediate
answer:
\begin_inset Quotes eld
\end_inset
any space with pseudo-Riemannian geometry
\begin_inset Quotes erd
\end_inset
.
This one goes full-circle, ending where we started, with a tautology.
\begin_inset Quotes eld
\end_inset
Assume Minkowski, therefore time
\begin_inset Quotes erd
\end_inset
.
\end_layout
\begin_layout Standard
There are curiosities on this path: e.g.
the Godel solution for EFE, describing a rotating universe.
It has closed time-like loops.
More generally, there are all sorts of time-like vs space-like confusions
marked by boundaries that are event horizons.
Thus, perhaps we can loosen the conditions, and ask
\begin_inset Quotes eld
\end_inset
do manifolds with event horizons necessarily have a Minkowski-space tangent
spaces?
\begin_inset Quotes erd
\end_inset
or are there other kinds of manifolds that have event-horizon-type structures?
This question is not well-posed.
Take it to be a poetic, inspirational question.
\end_layout
\begin_layout Standard
So that kind of exhausts classical physics.
Yes, there are differentiable structures, wherein something in those structures
can be given the interpretation of
\begin_inset Quotes eld
\end_inset
time
\begin_inset Quotes erd
\end_inset
, or can plausibly be identified with the physics concept of
\begin_inset Quotes eld
\end_inset
time
\begin_inset Quotes erd
\end_inset
.
Fine.
Great.
It does not at all address the question of
\begin_inset Quotes eld
\end_inset
Why are we trapped in the here and now? Why can we remember the past, but
not change it? Why can't we remember the future? Why do we think we have
free will to change the future?
\begin_inset Quotes erd
\end_inset
I utterly fail to see how anything in the classical theory differentiable
manifolds can have any bearing on these questions.
So punt on that.
\end_layout
\begin_layout Standard
Next on the agenda: quantum.
\end_layout
\begin_layout Standard
First, lets recap what quantum is.
Its a thing with an action, where the action can be minimized with Euler–Lagran
ge or Hamilton–Jacobi, giving classical equations of motion.
Close to these minimizing (or stationary) solutions, within one hbar of
distance, are other (differentiable) paths/surfaces.
They are necessarily differentiable, since the action has derivatives in
it, and so non-differentiable paths/surfaces would result in an infinite
(or undefined) action.
The partition function is
\begin_inset Formula $Z=\int\left[d\phi\right]\exp iA\left(\phi,\partial\phi\right)$
\end_inset
so anything with infinite/undefined
\begin_inset Formula $\partial\phi$
\end_inset
cannot contribute.
I belabor this point, because lots of fractals are non-differentiable everywher
e.
Such fractals often have perfectly well-defined measure theory behind them,
i.e.
are integrable, and so they can show up in measure-preserving dynamical
systems.
So, there's a bit of unresolved tension, here: illustrating how differential
equations (time-reversible ones, at that) give rise to measure-preserving
dynamical systems and systems having an action.
The prototypical
\begin_inset Quotes eld
\end_inset
answer
\begin_inset Quotes erd
\end_inset
is Sinai's billiards, where each reflection is time-reversible, momentum/energy
-preserving, but ergodic and non-differentiable in the limit.
For now, that's a step too far; see however below.
\end_layout
\begin_layout Standard
Anyway, changing gears.
If one imagines replacing derivatives with differentials, thus discretizing
the problem, then the differential eqn that gives a stationary point of
the action can be imagined to be ..
watch for it: a collection of jigsaw puzzle pieces, marked with tabs and
connectors, stating how the differentials can be legally combined to given
an expression for the action.
\end_layout
\begin_layout Standard
Are there two types of these jigsaws? One type, when assembled, giving the
stationary solution, while others, with looser assembly standards, that
give nearby solutions? There's also a counting problem: the classical solution
is a point.
How many nearby solutions are there? What's the measure?
\end_layout
\begin_layout Standard
The problem here is that we once again take a god-like view: there is a
classical action, we know it for all time.
We stick it in the quantum partition function, and again know it for all-time.
We do not have an adequate theory for the measure of such systems, but
so what: imagine we did: it affords us a god-like view, where we see not
just the past, but imagine being able to see the future, too.
\end_layout
\begin_layout Standard
Many-worlds has a curious role here.
So, on the one hand,
\begin_inset Formula $\int\left[d\phi\right]$
\end_inset
is meant to be an integral over all worlds, in the many-worlds interpretation.
On the other hand, all of these other worlds are assumed to be like ours:
predominantly classical, i.e.
given as solutions to the classical action.
But there is only one solution to the classical action, not many.
So either we are wrong about the action, or we are wrong about
\begin_inset Quotes eld
\end_inset
many
\begin_inset Quotes erd
\end_inset
.
That is, we either need an action with
\begin_inset Quotes eld
\end_inset
many
\begin_inset Quotes erd
\end_inset
classical solutions, or we are correct about our action (the Standard Model
is correct) and we are incorrect about there being
\begin_inset Quotes eld
\end_inset
many
\begin_inset Quotes erd
\end_inset
solutions.
\end_layout
\begin_layout Standard
I propose one way out of this dilemma: time.
At any given point in time, any
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
, we do not yet know which future will be the one, true, action-minimizing
future.
So we keep tabs on them all,
\begin_inset Quotes eld
\end_inset
until later
\begin_inset Quotes erd
\end_inset
, when we can
\begin_inset Quotes eld
\end_inset
find out
\begin_inset Quotes erd
\end_inset
.
Think of this as a computer weather simulation: numerical integration results
in numerical errors, but we wish to minimize those errors.
If course, they can be minimized locally, by picking a finer grid, but
better is to minimize them globally: say, minimize the root-mean-square
of all numerical errors, across the entire simulation.
This would require, at each
\begin_inset Quotes eld
\end_inset
point
\begin_inset Quotes erd
\end_inset
in the simulation, to track
\begin_inset Quotes eld
\end_inset
many different worlds
\begin_inset Quotes erd
\end_inset
, and then, at some point, select the one that minimizes the errors, thus
\begin_inset Quotes eld
\end_inset
collapsing
\begin_inset Quotes erd
\end_inset
the many choices to fewer choices.
This collapse would probably have a forward-backward nature to it: interferomet
ric, so different paths are pursued, and welcher-weg cannot be answered
until
\begin_inset Quotes eld
\end_inset
later
\begin_inset Quotes erd
\end_inset
, when the paths are brought back together and summed.
\end_layout
\begin_layout Standard
In this interpretation, the many-worlds aren't some mysterious
\begin_inset Quotes eld
\end_inset
parallel universes, just like our own, but different
\begin_inset Quotes erd
\end_inset
, but are rather an accounting trick, because we cannot actually minimize
the action *right now*, we will have to wait for the future to happen,
before that can be done.
In the meanwhile, track a giant pile of possible universes.
The
\begin_inset Quotes eld
\end_inset
past
\begin_inset Quotes erd
\end_inset
then becomes what has been resolved and frozen.
The future remains unknown.
This has aspects of the
\begin_inset Quotes eld
\end_inset
transaction interpretation of QM
\begin_inset Quotes erd
\end_inset
(TIQM) in that future events (results of interferometric comparisons) finally
fix past events (that point where the split along the two arms of the interfero
meter started).
\end_layout
\begin_layout Standard
BTW, I should mention: TIQM seems to fit well with the two state-vector
formalism (TSVF) and seems to be compatible with weak measurements (from
what I can tell.)
\end_layout
\begin_layout Standard
This, the TIQM or variants thereof, would seem to indicate that
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
is not an infinitely thin space-time slice, but rather of finite width.
And, not a fixed finite width, but multi-scale.
Small interferometers can be resolved in femtoseconds, bigger ones in milliseco
nds.
e.g.
the Alain Aspect experiments look at phenomena where the collapse is delayed
for milliseconds.
That is, the Aspect experiments probe
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
, where the width of
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
is milliseconds.
The shmucks working on quantum computing are suffering because they want
to create complex states that remain entangled for seconds or longer.
They talk about
\begin_inset Quotes eld
\end_inset
thermal noise
\begin_inset Quotes erd
\end_inset
collapsing their systems.
They are partly right: yes, they need to build systems that are isolated,
insulated from the rest of the universe, and all the thermal fiddle-faddle.
But the microscopic model needs to be that some
\begin_inset Quotes eld
\end_inset
photon
\begin_inset Quotes erd
\end_inset
from the outside world came in, bonked your superposition, which is bad
but not fatal, but then another photon left your superposition and bonked
the external world, which is fatal: you now have the two arms of an interferome
ter, and one arm of the interferometer is tangled into the universe, the
other is tangled into your superposition, and so, kaboom, your state collapses
before you get the chance to actually accomplish any meaningful quantum
\begin_inset Quotes eld
\end_inset
computation
\begin_inset Quotes erd
\end_inset
.
This is the engineering problem that is
\begin_inset Quotes eld
\end_inset
well-understood
\begin_inset Quotes erd
\end_inset
that everyone in the industry
\begin_inset Quotes eld
\end_inset
groks
\begin_inset Quotes erd
\end_inset
.
What I'm trying to do here is to argue that a TIQM type model is actually
the correct model.
This should be relatively non-controversial: there are many legit physicists
who believe in TIQM, even if they are a minority.
I'm trying to explicitly rule out the cranks and shysters.
I want nothing to do with

\end_layout
\begin_layout Standard
OK.
I think that kind of exhausts the quantum side of things.
It does sketch why there is a
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
, and it does answer why the future is unknown.
The future is unknown because some CMB photon could arrive on Earth, and
do the butterfly-effect thing.
Or worse: some primordial neutrino.
Until those neutrinos pass by, and do their butterly-effect thing, we cannot
know the future.
\end_layout
\begin_layout Standard
Careful: the standard retort here is that its
\begin_inset Quotes eld

small and negligible
\begin_inset Quotes erd
\end_inset
which is perfectly true for determining if the Flatiron building in New

But I'm philosophizing here: the integral
\begin_inset Formula $\int\left[d\phi\right]$
\end_inset
includes everything, including primordial neutrinos.
They may have negligible effects on practical calculations ...
they *must* have negligible effect, as otherwise practical calculations
are impossible.
But from the viewpoint of
\begin_inset Quotes eld
\end_inset
why are we trapped in the here-and-now?
\begin_inset Quotes erd
\end_inset
I cannot ignore their contribution.
I don't have some explicit calculation where I can say

Hmm.

The above reduces quantum many-worlds to a book-keeping device, the books

But it also makes things very mechanistic: some primordial neutrino has
some effect.
Sure, we use complex numbers, etc.
to perform that calculation; the conventional theory is what Kamiokande
is built on.
Rather, what I'm doing is to reduce many-worlds to a many-body problem,
a statistical-mechanics problem.
Yes, its

\begin_layout Standard
Anyway, all of the above now necessitates getting into the third leg: a
review of many-body statistical mechanics.
Mostly, in this section, I will recapitulate everything I learned since
the day I met Dean Driebe, and how he told me he could explain the arrow
of time with the Frobenius-Perron operator.
And this is an important insight.
And mainstream physics even got a bad case of
\begin_inset Quotes eld
\end_inset
Koopmanitis
\begin_inset Quotes erd
\end_inset
, cause everyone saw that this is an important insight.
So in my recap, I will try to imagine how Ruelle-Frobenius-Perron can be
reconciled with QFT, wave function collapse (a la TIQM) and see if it provides
insight into the prison of
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
.
But first, I take a break, because (a) its dinner, and (b) there are other
things I should be doing, and need to get done.
So maybe till tomorrow, or later.
\end_layout
\begin_layout Standard
Oh, before I break: there is a rather stark issues that arises with timescape
cosmology.
So, with conventional Frobenius-Perron (FP), the language is of ergodic
theory.
The canonical physics model is gas-in-a-box.
And that's fine.
But what about empty space? How is it that
\begin_inset Quotes eld
\end_inset
time is running
\begin_inset Quotes erd
\end_inset
in
\begin_inset Quotes eld
\end_inset
empty space
\begin_inset Quotes erd
\end_inset
, when there's no matter, no atoms in it? Well, two answers: (a) even in
cosmic voids, one can expect to find one hydrogen atom every ten cubic
meters (ts like one per cubic meter.
in cosmology, on average, but most of those are in galaxies, so presumably
the cosmic voids are a few orders of magnitude down from that.) So the voids
aren't
\begin_inset Quotes eld
\end_inset
really empty
\begin_inset Quotes erd
\end_inset
.
They also contain thousands(?) of CMB photons per cubic meter, and almost
that many (non-interacting) neutrinos, so even these voids aren't truly
\begin_inset Quotes eld
\end_inset
empty
\begin_inset Quotes erd
\end_inset
.
They also contain a bunch of (non-interacting, pressure-less) cold dark
mater.
Is this amount of non-emptiness sufficient to make an argument about ergodcity
and Frobenius-Perron? I don't know.
Alternative answer (b) is quantum zero-point fluctuations.
Given that these are off by 120 orders of magnitude, it's perhaps moot,
but it does give an opportunity to head-scratch and wonder
\begin_inset Quotes eld
\end_inset
what is the mechanism that wipes out quantum ZP from cosmological lambda?
\begin_inset Quotes erd
\end_inset
\end_layout
\begin_layout Standard
The point here was supposed to be
\begin_inset Quotes eld
\end_inset
Is it possible to have a here-and-now in 'empty' space?
\begin_inset Quotes erd
\end_inset
because there's no subject/object in empty space that can perceive time.
Because we can zoom out and take the gods-eye view of empty space, slap
a coordinate chart on it, and be utterly lacking in the ability of saying
\begin_inset Quotes eld
\end_inset
this is where 'now' is
\begin_inset Quotes erd
\end_inset
.
What we can do is to define comoving coordinates relative to last-scattering,
and use that to define

\end_layout
\begin_layout Standard
Oh, fucking footnote time.

This provides an anthropocentric argument that astronomical telescopes
cause the collapse of wave-functions in 100 mega-parsec-distant voids.
I fucking hate these anthropocentric arguments.
But it does get across the point that large-scale quantum entanglements
are participating in the time-evolution of the universe, even if they are
negligible in any practical calculation.

The Wiltshire/Burchert idea: Burtchert defines averaging.
He or Wiltshire note that walls are spatially flat, voids have negative
curvature.
Some quotes:
\begin_inset Quotes eld
\end_inset
a substantial difference in clock rates arises cumulatively over the lifetime
of the universe from the tiny relative volume deceleration of voids as
compared to wall regions (Wiltshire 2008).
The magnitude of this relative deceleration, typically of the order of
\begin_inset Formula $10^{-10}m/sec^{2}$
\end_inset
...
apparent acceleration is only registered once the void fraction reaches
a critical threshold of 59 per cent, typically near a redshift z∼ 0.9 (Wiltshire
2007a) ...
voids (typically of diameter ∼30 h−1 Mpc and smaller) ...
Large gradients in Ricci scalar curvature are assumed to exist between
the walls/filaments and the voids, consistent with observations that the
latter have density contrasts close to δρ/ρ∼−1 ...
The Hubble ‘constant’ inferred in this manner should peak at the dominant
void scale 30h−1 Mpc, i.e.
at z∼ 0.01, with a maximum value up to 17 per cent greater than the global
average and then steadily decrease to near the global average value when
the scale of statistical homogeneity is reached.
...
the scale of statistical homogeneity represents a redshift of the order
of z∼ 0.033, ...

The intro provides a summary sufficient for my purposes.
So maybe I won't have to read anything else.
The upshot is that our wall is moving away from other walls faster than
average, because there is a void in the middle.
Things average out, though the farther one goes.
Expect to see average expansion rates at
\begin_inset Formula $0.033<z$
\end_inset
and faster expansion rates at
\begin_inset Formula $z<$

0.01.
Clocks in the walls run slower than clocks in the voids.

Related is the idea of the

This gives another reason to exclude low-z SNIa data.
\end_layout
\begin_layout Standard
So here's the deal, now that I read the whole paper.
The timescape idea is a collection of formulas that explain how to compute
cosmological parameters, due to inhomogeneities, at scales *larger* than
than our local void or supervoid, or, more precisely larger then
\begin_inset Formula $z=0.033$
\end_inset
.
At those higher z'es, there are still voids and walls, but now there are
enough of them that meaningful averages can be taken over them.
Thus, data cuts are needed: exclude nearby SNIa that are in our known local
inhomogeneity region, and use the *correct* formulas for averaging over
inhomogeneities at farther distances.
This makes sense to me.
Go out far enough where you can take meaningful averages, and then use
correct averaging formulas.
Doh! This is a pretty solid argument, even if you are a firm lambdaCDM
believer.
I mean: treat your data correctly.
Who would argue against that? So I close the chapter on timescape.
I get it.
Cool.
Crank the data.

I guess I could go off on another tangent: atomic clocks.
But I'm thinking this is also unilluminating: these provide quantum systems
that are exceptionally stable.
They measure the passage of
\begin_inset Quotes eld

\begin_inset Quotes erd
\end_inset
which is necessarily related to the centroid of our non-zero width thermal-enta

That is, we live in a thermal bath of quantum entanglements, and so I would
estimate the thermal with of
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
to be given by
\begin_inset Formula $\hbar/2\sim E\Delta t$
\end_inset
and
\begin_inset Formula $E\sim kT$
\end_inset
and
\begin_inset Formula $T\sim300^{\circ}K$
\end_inset
and so
\begin_inset Formula $\Delta t\sim\hbar/2kT\sim6.6\times10^{-16}eV\cdot sec/(2\times8.6\times10^{-5}eV/K\times300K\sim10^{-13}sec$
\end_inset
so that's 100 femtoseconds or a tenth of a picosecond as an order of magnitude
expression for the width of
\begin_inset Quotes eld

\begin_inset Quotes erd

in our ordinary world.
Note that atomic clocks like to bring the temperature down (e.g.
cesium fountain) and the stated reasons and physical principles never use
a language like
\begin_inset Quotes eld

\begin_inset Quotes erd

Heisenberg uncertainty is meant to be a manifestation of what Fourier transform
s do to waves, and that is all well and good, but the fact that some experiments
have to deal with thermal motion at the same energy scale suggests that
we don't
\begin_inset Quotes eld

\begin_inset Quotes erd

Or it is possible that many-worlds really do exist.
This would require the the action that minimizes the partition function
to have a tree structure.
Which to me sounds crazy, because I've never seen any such, and it would
be a black swan.
But I can now imagine an analog: the beta expansion.
To be clear, this one:
\begin_inset Formula $x=\sum_{n}b_{n}\beta^{-n}$
\end_inset
where
\begin_inset Formula $0\le x\le1$
\end_inset
is some real number,
\begin_inset Formula $1<\beta\le2$
\end_inset
is another real number, the base, and the
\begin_inset Formula $b_{n}$
\end_inset
are binary bits.
Then, depending on
\begin_inset Formula $x$
\end_inset
and
\begin_inset Formula $\beta$
\end_inset
there are often many, infinitely many different bit-sequences which satisfy
this relation.
What's more, the bit-sequences can be arranged in a tree: i.e.
identical up to a certain length, and then they diverge.
There's even a phase transition, located at
\begin_inset Formula $\beta=\phi$
\end_inset
the golden mean.
I've written multiple papers on this.
\end_layout
\begin_layout Standard
Anyway, if
\begin_inset Formula $x$
\end_inset
can be thought of as
\begin_inset Quotes eld
\end_inset
minimizing something
\begin_inset Quotes erd
\end_inset
(i.e.
the action) and
\begin_inset Formula $\beta$
\end_inset
is some fixed
\begin_inset Quotes eld

cosmological constant
\begin_inset Quotes erd

\begin_inset Formula $b_{n}$
\end_inset
are the
\begin_inset Quotes eld
\end_inset
world lines
\begin_inset Quotes erd
\end_inset
of observers, forking where forks are possible.
So this is some zero-dimensional inspirational example of many-worlds.
Note that the binary digits are generated by iterating
\begin_inset Formula $\beta x\mod1$
\end_inset
and so there is a folding-back.
In some hand-wavey way, maybe this folding-back resembles the reflecting
boundary conditions for AdS.
Maybe that's why you can do QG models on AdS.

So the above is a simple model of a branching structure.
If instead, we insist that, no, there is only one

a shot.
That is, free-will is deterministically constrained, up until those branch

Note that the

before a branch-point appears.

It was thrilling.
Almost an ecstatic vision of truth and reality, sublime and supreme.

And oddly, I agree.
The song is 'Stand Inside Your Love', Smashing Pumkins.
When I listen to it, it is very much a transcendental mystical experience.
Now, many of the comments call it the 'best love song ever'.
But they never ask 'love for who?', implicitly assuming another human.
On my first listen to this song, for the first time ...
it was clear that Billy was singing about Jesus, or about God, that this

So of course it's transcendental.

Several ideas churned.
The Painleve chart says that the fabric of spacetime falls into anything
massive.
This includes point particles e.g.
baryons and electrons.
The Higgs mechanism says electrons get mass through the Higgs field.
Why would this coupling cause spacetime to curve? The baryons get their
mass from confinement.
This is an even bigger effect! Why would confinement bend spacetime? The
previous diary entries above deduce that the wall of time is a zero-point
effect hinged on the QSL.
But zero-point is some ergodic many-body process I don't understand.
There's some knot that ties these topics together.

Meanwhile, Owen says that he might get Stephen Wolfram as an advisor on

So of course, he has Wolfram's fat book on his coffee table.
I effing hate that book.
I'd love it if it was undersold, but its oversold hype.
The meanest thing I can think of saying is that Wolfram slept through the
part of class where they explained Newton Differences.
WTF.
The over-selling just makes it cranky.
It would be compelling if there was a Minkowski-covariant definition of
cellular automata.
Arguably, this would be possibly acceptable for the wall-of-time idea.
Zero-point is some Minkowski-covariant (invariant) ergodic process.
I don't understand it.
I do understand conventional QFT; I do not understand how it becomes ergodic.
I understand the Bernoulli process, I don't understand how QFT is Bernoulii-lik
e.
I understand tensor algebras.
Is the ground QFT state supposed to be some coherent state defined on a

\begin_layout Standard
Is it possible that gravitation drives weak mixing? That weak mixing is
a root cause of entanglement? The conventional answer is a flat-out no;
entanglement is just the algebra of representation theory of simple Lie
groups, and specifically the representations of su(2) and/or sl(2,C).
Fine.
But why is there entanglement between oscillators in different parts of
space? Why is flat space Euclidean, with the standard topology, instead
of a collection of points with a fine topology? What causes different points
in space to couple, causing the fine topology to collapse into the standard
one? The conventional answer would be
\begin_inset Quotes eld
\end_inset
derivatives
\begin_inset Quotes erd
\end_inset
: you can't form a derivative on the fine topology.
So that converts the question:
\begin_inset Quotes eld
\end_inset
why are there derivatives?
\begin_inset Quotes erd
\end_inset
Derivatives couple neighboring points.
What causes that coupling to happen? This is partly what the Wolfram idea
is about.
The problem with Wolfram is he chucks the idea of a derivative out the
window, but commits a greater crime of assuming a square lattice-grid topology.
God-knows, maybe he's moved on to hexagonal grids, or even sphere-packing
grids.
I ain't gonna read that book.
\end_layout
\begin_layout Standard
If you're going to discard derivatives and replace them with cellular automata,
then what's clearly needed is some definition of cellular automata on some
random grid.
That random grid has to course-grain into 3D space (and I guess that's
what the Planck-scale loop quantum gravity (LQG) people are saying.
I have not read their stuff, either.) But this should be a generic topological
trick: define some random graph, and show that it coarse-grains to n-dimensiona
l Euclidean space with the standard topology.
(Locally flat; we use that as a tangent space for
\begin_inset Quotes eld
\end_inset
real
\begin_inset Quotes erd
\end_inset
Riemannian geom.
and/or symplectic geom.) Then we get lost in the weeds.
Conventional algebraic topology tells use about singular homology.
So we do some singular homology on this random grid, and get ...
what? Famously the watchamacallit theorem says that there is no one-to-one
correspondence between tessellated surfaces and continuous ones.
But maybe that doesn't matter.
\end_layout
\begin_layout Standard
An additional point of confusion: If I'm working with random graphs, I guess
I'm supposed to be working with ensembles of such graphs? The ensemble
is needed to provide averaging properties.
The random-graph ensemble replaces the ensemble in the QFT functional integral.
That is, instead of having
\begin_inset Formula $\int\left[d\phi\right]$
\end_inset
with
\begin_inset Formula $\phi=\phi\left(x\right)$
\end_inset
some field over points
\begin_inset Formula $x\in M$
\end_inset
for some space(-time)
\begin_inset Formula $M$
\end_inset
, we instead sum with
\begin_inset Formula $\sum_{g\in G}$
\end_inset
for random graphs
\begin_inset Formula $g$
\end_inset
in an ensemble of graphs
\begin_inset Formula $G$
\end_inset
.
We then work with the singular homology for each
\begin_inset Formula $g$
\end_inset
to determine the dimension of the space.
i.e.
homology groups need to vanish in all dimensions except the desired dimension.
Or rather, its OK if they don't vanish for some of the
\begin_inset Formula $g\in G$
\end_inset
but, when averaged over all of the
\begin_inset Formula $g\in G$
\end_inset
they do.
So that for a singular homology
\begin_inset Formula $H_{n}\left(g\right)$
\end_inset
for a graph
\begin_inset Formula $g$
\end_inset
we construct
\begin_inset Formula $H_{n}\left(G\right)=Z^{-1}\sum_{g\in G}H_{n}\left(g\right)$
\end_inset
where
\begin_inset Formula $Z^{-1}$
\end_inset
is some normalization (playing the role of the partition function.) Maybe
I should use a different notation than
\begin_inset Formula $Z$
\end_inset
to avoid confusion about using
\begin_inset Formula $Z$
\end_inset
for cycles.
\end_layout
\begin_layout Standard
Several problems with this idea.
First, in flat space, all homology groups vanish.
So this trick doesn't actually tell us what the dimension of the space.

But that would be stupid) So that's a big fail.
I fucked up in saying
\begin_inset Quotes eld
\end_inset
homology
\begin_inset Quotes erd
\end_inset
, I need some other construction that measures something that looks like
dimension.
Second, to have a meaningful sum there should be some action
\begin_inset Formula $A\left(g\right)$
\end_inset
so that
\begin_inset Formula $Z=\sum_{g\in G}\exp iA\left(g\right)$
\end_inset
.
This differs from conventional Ising-model stuff, in that we are summing
over all graphs
\begin_inset Formula $g$
\end_inset
and not over all field configurations on a fixed lattice.
But what's
\begin_inset Formula $A\left(g\right)$
\end_inset
? Where does it come from? What value does it take? Why?
\end_layout
\begin_layout Standard
The weight
\begin_inset Formula $\exp iA\left(g\right)$
\end_inset
is understood to provide a measure-theoretic-like measure for each
\begin_inset Formula $g$
\end_inset
.
But, when doing the transfer operator for the Bernoulli process the sum
arose from working the ergodic map backwards, i.e.
the root origin of the
\begin_inset Formula $\sum_{g\in G}$
\end_inset
came instead from a
\begin_inset Formula $\sum_{x\in f^{-1}\left(y\right)}\left|\left(f^{-1}\right)^{\prime}\left(x\right)\right|^{-1}$
\end_inset
which I wrote wrong, but the weighting is given by a Jacobian.
I'm trying to capture the generic ergodic process idea and tie it back
to
\begin_inset Quotes eld
\end_inset
where does the action come from
\begin_inset Quotes erd
\end_inset
? and reformulate
\begin_inset Quotes eld
\end_inset
the action
\begin_inset Quotes erd
\end_inset
as the
\begin_inset Quotes eld
\end_inset
log of the Jacobian
\begin_inset Quotes erd
\end_inset
.
I'm confused.
Why have I not tried this before, in my formal work? Probably because it
was unenlightening for those simple cases.
Maybe I didn't spend enough time thinking about how and why it could be
interesting.
I should go back and try some force-fits of this idea and see what happens.
\end_layout
\begin_layout Standard
We can now hand-wave our way to the goal posts.
For each vertex in
\begin_inset Formula $g$
\end_inset
place some cellular automata there, and let it interact with neighboring
points in some way.
These interactions provide some value for
\begin_inset Formula $A\left(g\right)$
\end_inset
and then, given appropriate interactions, we find that the dominant contributio
ns to
\begin_inset Formula $Z$
\end_inset
are given by graphs that coarse-grain to an n-dimensional Euclidean topology.
Or maybe 3+1 for all the space-time nuts out there.
\end_layout
\begin_layout Standard
What have we achieved here? Well, *maybe* it provides a path from random
grids to flat space.
But the fact that there's a sum over an ensemble suggests that the resulting
space will be
\begin_inset Quotes eld
\end_inset
quantum
\begin_inset Quotes erd
\end_inset
.
So I guess I've invented
\begin_inset Quotes eld
\end_inset
quantum space
\begin_inset Quotes erd
\end_inset
? And we do want
\begin_inset Quotes eld
\end_inset
quantum space
\begin_inset Quotes erd
\end_inset
, and I'm assuming that the LQG people have developed some technology that
replaces my hand-waving with something more precise.
My only quibble with LQG is that it should work for spaces in any dimension,
not just Minkowski space, but genericaally for any space with a metric
with signature (m,n) (i.e.
for any Riemannian or pseudo-Riemannian space).
If you want to say (3,1) is special, then the specialness has to come from
somewhere else.
\end_layout
\begin_layout Standard
To conclude: maybe one can take ensembles of random graphs, and define an
(arbitrary-dimensional)
\begin_inset Quotes eld
\end_inset
quantum space
\begin_inset Quotes erd
\end_inset
that way.
Seems plausible.
But this leaves the question of
\begin_inset Quotes eld
\end_inset
why are we trapped in the now?
\begin_inset Quotes erd
\end_inset
unanswered.
Which does seem special to 3+1 especially given the weirdness of how propagator
s for the wave equation work in dimensions other than 3+1.
\end_layout
\begin_layout Standard
I dunno.
This is a train-wreck of ideas.
They all might actually be good ideas, but they all require some huge amount
of work to refine and define and formalize and make exact.
And me being lazy, I'm looking for the silver bullet.

Back to AGI.
For the last several days/weeks (month?) I've been trying to reconceptalize
similarity measures.
I've got jumbled ideas, none of them want to gel, and I can't write them
into a project README because they are incoherent.
However, this diary is a safe space for incoherent ideas put forth by snowflake
s who fear public perception when voicing their most private thoughts.
Not here, buddy, we love you.
You can ramble incoherently all you want.
Let it out.
Lit it out of your system.
Let it all come out.
We love you.
\end_layout
\begin_layout Standard
So I could jam the basis elements for a sparse vector into some new atom,
in some c++ set but why? the atomspace already provides container-like
constructions.
But we don't want sets, we want membership.
But membership is rather fat: millions of new links.
Atoms are a bit pudgy: 713 bytes per atom for one recent dataset.
Keeping this in a C++ vector could be as little as 24 maybe 48 bytes/atom.
\end_layout
\begin_layout Standard
On the fly lookup could that work? Because we maybe we don't need to keep
anything? But we do, cause on the fly is slow.
Esp if using the query engine to do the on-the-fly stuff.
\end_layout
\begin_layout Standard
Whats a vector embedding anyway? For the word-pairs, there were explicit
links to left and right, and a wild-card in either gives the vector.
For generic patterns, those patterns would need to have exactly two variables.
Thence confusion: because we are using the wild-card to define the embedding,
and also to fix the other side.
These two distinct roles are mashed into one.
Can they be detangled?
\end_layout
\begin_layout Standard
Sort of.
For an embedding to work, all vectors must share the same same basis, as
otherwise they are incomparable.
Sof ro that a single-variable pattern suffices.
Well, no: still two: one variable as wild-card, and the other one fixed
to the item, because this is how we guarantee that the vectors have the
same basis.
\end_layout
\begin_layout Standard
Word-pairs exploited a loophole of left-right conjugacy: instead of having
one pattern with two distinguised slots, there were two patterns, with
the second just being the symmatric transpose of the first, by accident.
This is a happy accident, but cannot be taken to hold in general.
\end_layout
\begin_layout Standard
Well, except that it must.
Somehow it must be transposable....
which brings us back to the start: it must be a pattern with two slots.
OK, fine, I guess we can work with that.
\end_layout
\begin_layout Standard
So I've got a pattern with two slots.
A typical task is the cosine similarity, i.e.
dot product, so take two items that are to be compared, stick them in the
lefft slot of the pattern, find wildcards, multiply.
\end_layout
\begin_layout Standard
Two problems: one where do the weights come from? (assuming non-uniform
weighting) so pattern also has to indicate how to get a single float, or
maybe something more complex.
So this is not just a pattern, but also a key.
And since the thing on the key might be a vector, a vector offset.
Since it might be more complex than a vector, it needs to be some generic
pattern for accessing something in the value, and then also making it clear
how to multiply the said thing, pair-wise.
So a pattern that takes a pair of values and returns a single float.
\end_layout
\begin_layout Standard
A single float because that's all we can hope for in similarity.
We are not asking
\begin_inset Quotes eld
\end_inset
how are they similar
\begin_inset Quotes erd
\end_inset
, but instead
\begin_inset Quotes eld
\end_inset
how similar?
\begin_inset Quotes erd
\end_inset
\end_layout
\begin_layout Standard
A different problem is normalization.
We can run the search pattern for A B being two different leftvalues, and
find right-value wildcards, but there may be more wilds, both absent in
A,B.
So we need to run the full search comehow.
And this could be horridly cpu-bound.
So the result should be cached.
But maybe its OK to run this in parallel, and just keep a running queue.
Well, two running queues, one for left one for right.
And I guess sets would be ok, it does have to be lists, and deduplication
would be nice, since search will hammer lots of duplicates.
\end_layout
\begin_layout Standard
So the plan is, start the dual-wild card search.
Keep left and right groundings on two distinct but well known locations
on the pattern.
Allow access to them, even while the pattern is running.
Allow multi-threaded access.
OK, that all works and is straightforward in the current query engine implement
ation.
\end_layout
\begin_layout Standard
The sets are not atoms, so will not be bloated (will be smaller).
That's fine.
\end_layout
\begin_layout Standard
So all we need is two well-known keys on the pattern.
And a modified pattern traversal that know to put things there.
So a new pair-wise query atom.
OK fine.
easy, not bloated.
Acceptable, not paradigm breaking and not slow and not bloated.
So green light all around.
\end_layout
\begin_layout Standard
That's just part one, though.
Part two is the weights.
There are other parts, including GPU concerns, and including stream processing
concerns.
Those go on back burner.
One thing at a time.
Lets make sure we've got part one done:
\end_layout
\begin_layout Standard
– a new query atom with two slots.
The slots could be either well-known names like (Prediate
\begin_inset Quotes eld
\end_inset
left side
\begin_inset Quotes erd
\end_inset
) and (Predicate
\begin_inset Quotes eld
\end_inset
right side
\begin_inset Quotes erd
\end_inset
) or they could be the left and right variable decls themselves.
If left and right variable decls, then either the bare variables, or the
variables with the type signatures.
With type signatures might be best, because these are easy to find in the
pattern: they are necessarily at the top.
\end_layout
\begin_layout Standard
– what else? Is that it? did we miss something? Can I prototype this on
the file system? Yes, the file system provides a new an unique and different
dataset that hints at disclosing new difficulties.
\end_layout
\begin_layout Standard
one of these new difficulties is a recursive similarity.
Hold that thought.
Lets complete the first part.
\end_layout
\begin_layout Standard
So, we can do this for all searches: doesn't have to be two-variable, could
be n-variable.
The well-known location problem is solved, as well.
Why didn't I do this years ago? Shit, I want to code this *right now*,
its clear as a bell.
Obvious.

\begin_layout Standard
Fuck it.

\begin_layout Standard
Two ideas I want to jot down, before I forget them.
The first starts with the Minkowski Question Mark.
It has a lattice model, and it is an infinite-range lattice model.
I wrote it down some decades ago.
But I'm thinking this is a Hopfield network as well.
And so I'm thinking that maybe some of the famous properties of the question
mark reappear as properties of neural nets, more generally.
The interesting ones being those of differentiability.
\end_layout
\begin_layout Standard
More generally, if we have high-dimensional hypercubes, extremely long bit-strin
gs, these are ...
strings.
and strings are one-dimensional, and have 1D lattice models.
Sooo ...
well, the Minkowski question mark model when I wrote it down , had a infinite-r
ange interaction.
Did I screw it up, and fail to recognize this as a local lattice model
e.g.
i.e.
nearest-neighbor interactions, e.g.
an Ising model, on an infinite-dimensional lattice? WTF.
I have to go back and look at this again.
\end_layout
\begin_layout Standard
More generally, when do long-range interactions correspond to short-range
interactions in higher-dimensional models? The problem is its late at night,
and I'm tired.
But I had to jot this down for later exploration.
\end_layout
\begin_layout Standard
The other idea was about employing frames and locals for a description of
the thin layer of
\begin_inset Quotes eld

now
\begin_inset Quotes erd
\end_inset
.
As I go to write these words, it is awfully empty-sounding.
But when I got it, it seemed full.
F;rames and locales are the correct approach.
I think I have a book on this.

\begin_layout Standard
Set and setting.
Did a lot of walking (about 2 hours worth) yesterday, my legs hurt.
Bicycled 2.5 hours day before.
Today was Saturday, a day to take off from manic coding.
Read a marvelous physics paper: cosmology with torsion.
Just fantastic.
Apparently, Einstein–Cartan–Kibble–Sciama (ECKS) Theory makes torsion dynamical
, and does a minimal coupling to spin.
The result is that, in the action, the spin coupling is just algebraic;
no derivatives, so it does not propagate.
The torsion field is non-zero only where the spin is non-zero.
The result is a theory which looks exactly like conventional cosmology,
except that it has some small corrections to the energy-momentum tensor,
and to the pressure, that are negative.
By
\begin_inset Quotes eld
\end_inset
small
\begin_inset Quotes erd
\end_inset
, suppressed by a factor of G so truly very small.
The terms are significant only when fermions are extremely dense, far greater
than neutron stars.
Basically, before the era of neutrino decoupling during quark-gluon recondensat
ion.
Plugging through the current neutrino density into FLRW he gets ...
well, I'm putting the cart before the horse here.
The idea is that there's an era where the dominant force is a repulsive
torsional force.
I'm imagining a kind-of Pauli exclusion force, but its not that, because
its not a flatspace thing, and its instead a term in the action.
But I digress.
Plugging in current netrino densities, he sees it being dominant when universe
is one micron across, some 1e-43 seconds, when the
\begin_inset Quotes eld
\end_inset
a
\begin_inset Quotes erd
\end_inset
flrw term has a logarithmic correction, universe undergoes rapid expansion,
with antipodes moving apart at 1e6 c and an effective expansion of 1e63
so more than enough to obtain fine-tuning.
Also he claim right befoe this is high-viscosity, huge tidal forces, so
very strong mixing resulting in homgenization.
So basically, everything that scalar-field-driven inflation gives you,
but without the scalar fields.
Awesome idea, I'm buying it hook, line and sinker.
\end_layout
\begin_layout Standard
More, because he posits this also prevents formation of a singularity, with
the repulsion due to torsion bouncing things before the singularity forms.
Now, this is just a short 4-page-long Phys.
Lett.
so
\begin_inset Quotes eld
\end_inset
the singularity doesn't form
\begin_inset Quotes erd
\end_inset
is a Shwarzschild idea, and not a Kerr idea and I can say I've never read
about the collapse of a rotating star, and the formation of a singularity
there, and of course the Penrose diagram there ...
blah blah ring sinularity but clearly difficult to visualizes.
Anyway, author of paper posits that every newly form BH has a universe
on the other side of it.
\end_layout
\begin_layout Standard
I wonder how this squares with the mass-inflation models from what's-iz-name
...
which are built on top of the conventional interior solutions with some
low-density infalling dust ...
then there's that wonderful river model ...
so if I did not have to eat, sleep or be subject to some of the basic constrain

on this stuff.
But reality affords no such luxury: its now almost 9PM, and between now

\begin_layout Standard
The above are some vague complaints about mental exhaustion.
And I really really want to copy those formulas for the dynamical torsion
to my other physics diary, but fuck it.
Instead I am going to full-on word-salad stream-of-consciousness here about
graph counting.
The following won't make sense to you because I will not be making any
effort to explain what I'm writing or why I am writing it.
Sorry.
Sucks to be you.
This is for me, only.
\end_layout
\begin_layout Standard
So I figured out I can store marginals with patterns, and this is a great
idea, and I'm stumped as to why I didn't figure this out years ago.
I guess its a process.
So one of the processes is counting.
How? I can write a filter, I guess, and hook it to an input stream.
Maybe I should just do this and see what happens.
\end_layout
\begin_layout Standard
But this is irritating because (a) I have to write code, (b) it does not
directly tap into LLM ideas.
The solution that seems like it would be wanted would be some way of autogenera
ting code that would do the pipeline counting ...
running different variants of it in parallel ...
somehow selecting which of these are better, but how? How do we know when
one of these auto-gen'ed snippets is better?
\end_layout
\begin_layout Standard
Perhaps all this is too low-level.
Perhaps there is some phase-transition to general intelligence, and we
really do have to build enough basic frameworks before feedback processes
can kick in.
\end_layout
\begin_layout Standard
So back in the day, I was counting word-pairs and keeping large sparse vectors
thereof.
But ...
here I bonk.
I have to consult some references, now.
But it's quarter to ten at night I don't feel like it.
For performance I was using LG to do pair counting.
But this won't go onto GPU's, cause its not SIMD.
Great for multi-core, though.
\end_layout
\begin_layout Standard
Now that I
\begin_inset Quotes eld
\end_inset
fixed
\begin_inset Quotes erd
\end_inset
marginals, I can maybe redo a big multi-core LG counter.
But this takes me back to force-feeding the machine, when I wanted to have
it do the exploratory thing.
So does that mean I have to hand-code more of the exploratory pipe?
\end_layout
\begin_layout Standard
The meta issue is everyone is screaming LLM and GPU, which I ignore at my
own peril, and it seems to be quite perilous, indeed.
So I have to ...
go there.
Even though gut intuition says its a big honking waste of time.
Maybe my gut intuition is wrong.
Certainly, ten thousand engineers say I'm wrong, and a million hangers-on
are even more sure I'm wrong.
So do I buckle under peer pressure, and buck up and take it like a man?
Or do I go full-on non-conformist, just like always? Fuck it.
Let me consult that reference.
\end_layout
\begin_layout Standard
Done.
An hour later, and ...
foo.
Waste of time.
Where was I?
\end_layout
\begin_layout Standard
I need some system for wandering through a file system, opening and reading
files.
I need a tokenizer, a word-pair counter.
I need a way of storing counts.
Where do I store counts? Again, I can use an engineered solution.
Don't want that.
Lets g back to file system crawling.
Step one is
\begin_inset Quotes eld
\end_inset
remember where I've been
\begin_inset Quotes erd
\end_inset
.
So, log the URL and it seems OK to engineer that.
Next, what is the actual memory? Increment a count on each URL? At some
\begin_inset Quotes eld
\end_inset
well-known location
\begin_inset Quotes erd
\end_inset
? That's engineered, again, but maybe that's OK.
The file corruption project has the idea of witnesses, so that each sensorial
visit is tagged with a witness link, associating the URL to a time-stamp.
The sensorial device generated a variety of data, those are URL-asscited
tags, as well, dictated by the sensorial system.
So the sense says, basically: let me do things, and I will fill up the
atomspace with observations that include URL's, witnesses, file sizes,
file types, and whatever else that sensor conventionally
\begin_inset Quotes eld
\end_inset
wants
\begin_inset Quotes erd
\end_inset
to do.
For now, I guess, the sensor is engineered, and I guess that's OK, because
the activities are now defined by the sensor itself, as opposed to the
user of the sensor.
\end_layout
\begin_layout Standard
And this is perhaps the key distinction: the sensor acts as an agent,
\begin_inset Quotes eld
\end_inset
doing stuff
\begin_inset Quotes erd
\end_inset
, and leaving a trail of shit aka fermentation products aka
\begin_inset Quotes eld
\end_inset
output
\begin_inset Quotes erd
\end_inset
in the atomspace.
It behaves autonomously, and not under supervision.
A different agent, also acting autonomously, can be a counting agent: it
crawls over the ferment, and counts.
A third agent can then act as an inhibitory control, telling the first
sensory agent:
\begin_inset Quotes eld
\end_inset
now you've visited this place before, don't do it again
\begin_inset Quotes erd
\end_inset
.
(or maybe do do it again, because this time, we ratchet to some other higher
protocol level.)
\end_layout
\begin_layout Standard
So the architecture now has three pieces: a crawler, that crawls and generates
witness stamps.
It also publishes the format of what it is going to generate, as both a
pattern and a variable declaration.
So that others can look at it and see
\begin_inset Quotes eld
\end_inset
OK, that's the format of what you are generating
\begin_inset Quotes erd
\end_inset
Then there is a generic counter agent, which ...
takes any pattern whatsoever, as input, and increments on it, maintaining
a count.
Where? Anywhere.
The counter is also an agent, it can store wherever it wants, and it will
publish that location if anyone is interested.
It's part of the description.
The third part is supervisory, and tries to give suggestions to the crawler
to do this or that but not something else.
Two things are not clear: what the control interface to the crawler is,
and how the supervisor makes decisions.
\end_layout
\begin_layout Standard
So the sensor can dump data into the atomspace, but ...
the counter needs to know what
\begin_inset Quotes eld
\end_inset
fresh data
\begin_inset Quotes erd
\end_inset
is.
One idea was to have dataflow pipelines, so that the output of the sensor
is directly coupled to the input of the counter, and that LG style connectors
are used to accomplish this connection.
But still, the things in that pipeline are atoms, so they clog up the atomspace
, and ultimately need a pruning or forgetting agent to go with.
\end_layout
\begin_layout Standard
Is there a viable alternative to direct flow? Search is inefficient, esp
since we need to
\begin_inset Quotes eld
\end_inset
search for what's new
\begin_inset Quotes erd
\end_inset
.
Well, if we know that data is time-stamp-tagged, then the search is for
everything newer than the timestamp.
which is ugly if 99% of the atomspace pattern contents is older than the
timestamp.
There's also the old idea of dropping off new content at an anchor point.
That anchor point would then obviously be the sensor itself, and a part
of the sensor description would then be
\begin_inset Quotes eld
\end_inset
here are my anchor points
\begin_inset Quotes erd
\end_inset
.
Located at the anchors would be QueueValues or the UnisetVallues, so that
part is good to go.
So ...
there is no alternative to flow, but maybe its not so bad, because things
can flow into queues, even if there's no consumer.
\end_layout
\begin_layout Standard
Well, that works only till we run out of RAM.
So maybe there needs to be ..
oh fuck, why didn't I think of this earlier: an Atom dequeue malloc.
Today, in the atomspace, you can malloc an atom, and add it to atomspace,
without any penalty.
But perhaps there needs to be a control system: not more than N atoms allowed
inside.
Even by type: no more than N atoms of type X allowed inside.
Every atom insert then checks to see if its allowed, or not.
This does make atom insertion more costly.
\end_layout
\begin_layout Standard
So maybe this becomes a new
\begin_inset Quotes eld
\end_inset

system, layersed on top of the atomspace, that presents the AtomSpace interface
s, but performs validity checking before accepting inserts.
Which is cool, except the atomspace API is C++ and not atomese.
\end_layout
\begin_layout Standard
But QueueValue also does not have an Atomese interface: things get stuffed
into it via c++.
There's no
\begin_inset Quotes eld
\end_inset
EnqueueValueLink
\begin_inset Quotes erd
\end_inset
.
There's a SetValueLink that places a value at a key.
There's an atomic increment.
Perhaps teh atomic increment can be reporposed for non-numeric things to
mean
\begin_inset Quotes eld
\end_inset
atomic enqueue
\begin_inset Quotes erd
\end_inset
Wow.
OK, so that's a great idea.
See? free associating into this diary does work! Again! More than a few
times, even if its word salad to you.
This is very interesting because in college, I could not type this fast
and long-hand-writing didn't work, but maybe that is what the Enlightenment
was all about 300 years ago: write long diaries to yourself chewing over
ideas, forcing them to be just concrete enough to work, that you can force
it to happen, which is more difficult to do, whe not writing.
I get ideas when I walk around, but they are difficult to keep coherent,
because its like juggling: I have to keep it all live, as I walk around,
juggle and not drop the ball, but here, where a I free associate into text,
I can drop the ball, and its harmless and so fucking what.
Its in words.
The words will be there later, so tomorrow morning, if I forget what I
thought about today, I just look at this text, and go
\begin_inset Quotes eld
\end_inset
oh yeah, that's what I was thinking
\begin_inset Quotes erd
\end_inset
, which is something that I cannot do if I got my bright idea while walking
around, and forgot it by the next morning.
SO typing is, at a minimum, a personal memory prosthesis.
I mean, it clearly is culturally, but writing to myself in private somehow
works better than thinking to myself, without the writing.
And this is duh, yeah, that's why people keep diaires, and I'm rediscovering
the obvious, but sometimes the obvious is so fucking astounding.
The obvious should not be taken for granted.
The obvious is sometimes asounding and gobsmacking.
But I digress Lets get back on track.
\end_layout
\begin_layout Standard
So I have a QueueValue, but no way to enqueue things there, except by C++
interfaces.
So I guess I need an 'InsertIntoLink' that will insert.
The QueueValue is also unbounded in length.
So I kind of need to turn it into an agent, which says
\begin_inset Quotes eld
\end_inset
I have a built in length, and here is what my control mechanism is for adjusting
that length.
\begin_inset Quotes erd
\end_inset
\end_layout
\begin_layout Standard
Next, I have the UniSetValue which is a deduplicating set, which means it
is almost like an AtomSpace but not quite ...
I mean, it is implemented on top of the cogutils concurrent set, and its
NOT implemented on top of the atomspace, but perhaps it could or should
be?
\end_layout
\begin_layout Standard
So again we deal with historical design snafus.
Every atom contains a point that says
\begin_inset Quotes eld
\end_inset
here is the atomspace I belong to
\begin_inset Quotes erd
\end_inset
.
Is that pointer really needed? For implicit execution, yes, its nice.
Neither UniSet nor Queue need to force an atom into belonging.
Nether has the additional methods that the AtomSpace does for finding-by-type
and so on, but maybe we should put the atomspace on a slimming diet and
get rid of some of this crap that was always ugly? Wow.
That's actually another great idea, I guess.
Remove old and unused atomspace API crap.
\end_layout
\begin_layout Standard
Why does an atom need to know what atomspace it belongs to? Why can't the
atomspace be more like the uniset?
\end_layout
\begin_layout Standard
Another piece of atomspace crap is the get-atoms-by-type API, which feels
like a crutch.
But that crutch is used by the query engine.
So AtomSpace is actually a collection of Unisets, and it was custom-coded
that way in the distant past.
\end_layout
\begin_layout Standard
Unlike the uniset, the atomspace does not have a blocking remove and block
if empty
\begin_inset Quotes erd
\end_inset
and maybe it should? Wow.
This is a reasonable long-term evolutionary design to push for.
\end_layout
\begin_layout Standard
So we need an insert-into-link, and a dequeue-from-link.
And we need motor controls to allow a max-size to be set.
\end_layout
\begin_layout Standard
So this means create a new class of values: agent-values, which have sensori-mot
or interfaces on them, very simple ones, that say
\begin_inset Quotes eld
\end_inset
i can be inserted into, I can be removed from, and I have a size.
The atomspace is complex, because it also gets an
\begin_inset Quotes eld
\end_inset
I can be dequed be type.
\begin_inset Quotes erd
\end_inset
\end_layout
\begin_layout Standard
I need an insert-into-link, a dequeue-from-link, a get-contents-of-without-deque
ing link (make-a-copy-link), and a get-verything-and-empty-out-link.
Wow.
OK.
\end_layout
\begin_layout Standard
Well, one step at a time.
My mind boggles.
\end_layout
\begin_layout Standard
I've been here before.
I've had any number of great brainstorms, in the decade past, and I have
to acknowledge that many of the ideas were not quite right in their first
form, and had to be reworked two or three or four times.
So this queue/dqueue might not quite work out, but agentizing the infrastructur
e seems like a good idea.
It would certanily make the whole sensorimotor apparatus much easier to
implement.
Less hacking, more directness.
Immediate, concrete.
Huh.
\end_layout
\begin_layout Standard
It is now exactly midnight.
I'm signing off.
\end_layout
\begin_layout Subsection*
5 February 2025
\end_layout
\begin_layout Standard
OK.
So I wrote a bunch of stuff above, and I sat down to do it, but then got
interrupted, and then some time elapsed, and now I have no clue what the
plan is, so I have to recreate it from scratch.
Or I could read what I wrote above.
....
\end_layout
\begin_layout Standard
Re-reading above ...
there was concern about over-flowing a queue, but this seems immaterial
at the moment.
\end_layout
\begin_layout Standard
Then I talk about creating atomese that can place things on a queue, and
dequeue.
This is more interesting.
\end_layout
\begin_layout Standard
Related to this is that the atomspace is a big slosh-tank.
Kind of like UniSetValue but with extra stuff.
It feels like there's some unresolved tension here, but solving this right
now also seems lower priority.
Well, lets at least spell out what this is.
First, every atom as one pointer into the atomspace, which means any given
atom can belong to only one atomspace, ever.By contrast, one atom can be
placed into many UniSetValues.
And I guess this is OK.
Basically, it says that the atom has no incoming pointer to the uniset.
\end_layout
\begin_layout Standard
Should the atomspace be changed to be nothing more than a mutable link?
That is, remove the backpointer from the atom, and instead use the incoming-set
mechanism to indicate which atomspaces an atom belongs to.
This pointer does not seem to participate in any high-performance corridors,
so this change could be made.
But this is some nice-to-have theoretical cleanup and cleanliness and design
perfection that no one is going to notice or care about.
It changes very very little in how any ordinary user would perceive the
system.
So I'll queue this as a nice to have to-do list for the future.
And mostly-ish ignore it for now.
\end_layout
\begin_layout Standard
The original task was to compute vector similarity, with the vectors arbitrarily
defined, and coming from anywhere.
i.e.
from a search pattern.
So step one is to define a similarity-computing agent.
This agent needs to indicate that it can take two columns of data.
So it defines two input connectors.
For hamming distance, this is enough, because just set overlap is counted.
For cosine similarity, the connectors need to indicate that they also need
float point data, and the linker needs to link that up.
\end_layout
\begin_layout Standard
So now we come to the linker.
Hold that thought.
I am going to prototype something, right now.
The linker is the interesting part, but I want to get the prototype in
place, first.
\end_layout
\begin_layout Subsection*
5 February 2025 Ongoing
\end_layout
\begin_layout Standard
...
or not.
I'm wildly confused.
Let's consider Hamming distance.
There are multiple issues biting me.
There is an existing SizeOfLink that correctly returns set sizes.
There is no SetIntersectionLink to compute set intersections.
Should there be? Normally, this would be accomplished with a pattern query.
Or is it ...
how?
\end_layout
\begin_layout Standard
I've got R(x,y) a binary relation.
Fixing a, R(a,y) is a vector, and fixing b, R(x,b) is a vector.
Now want to find the set intersection: all y in R(a,y) such that they appear
in R(y,b).
So define an equality relation E(x,y) and compute the pattern R(a,y) and
E(x,y) and R(x,b) and the diagonal here is the intersection.
OK, that will work.
\end_layout
\begin_layout Subsection*
6 February 2025 Morning
\end_layout
\begin_layout Standard
Dear diary: here we go! We're going to have to settle into this; I've only
had a little over seven hours of sleep today, and my head is still groggy;
I normally have 9.5 hours of sleep, and wake ready to go.
But my sleep hygiene is mediocre: sometimes, I allow myself to think things
(force myself to think things?) that keep me awake, tossing and turning
in bed.
Were I to rise, I'd be fuzzy-headed and useless, so laying awake in bed
seems a better option.
But it is not always pleasant, either, as some thoughts turn anxious.
\end_layout
\begin_layout Standard
This is all, I presume, completely commonplace in humans, there must be
a million attestations of this.
But this one is mine.
\end_layout
\begin_layout Standard
But I've put off the main topic that I wish to write about, and now is the
time for it.
I'm still groggy headed, fuzzy, a bit slow.
Drinking coffee ...
will it kick in? How long before that
\begin_inset Quotes eld
\end_inset
normal feeling
\begin_inset Quotes erd
\end_inset
comes back?
\end_layout
\begin_layout Standard
So what was keeping me awake was that there are severe interpretational
difficulties of the idea of the prison of the here-and-now, with the idea
of Minkowski space.
So let me rewind back to the beginning.
Subjectively, we appear to be trapped in the here-and-now, unable to alter
the past, unable to remember the future.
Objective evidence that this is a physical truth, and not just a subjective
truth, is that evolution has given animals brains, wildly complex and sophistic
ated devices, designed to tackle the problem of prognosticating the future.
For example: there is a tiger in front of me, and he might eat me, so I
better use my free will, and get the fuck out of here.
The tiger has a brain, too:
\begin_inset Quotes eld
\end_inset
oh no, my prey is running away! If I don't go catch it, I'll starve!
\begin_inset Quotes erd
\end_inset
If everything was pre-determined, as is occasionally argued by some certain
small class of physics-philosophers, then nature would not have evolved
brains.
If all was predetermined, I would not need a brain to run away, and the
tiger would not need a brain to catch me.
Wed both reduce caloric demand associated with thinking, and do some other
organismic thing, instead.
So clearly, the here-and-now is a physical truth.
\end_layout
\begin_layout Standard
In the weeks, months and years earlier in this diary, I've attempted to
articulate a picture of the here-and-now as a frothy quantum turbulent
front of not-yet-settled, not-yet quantum-collapsed boundary between past
and future.
It has some finite width, and more properly, not a single width, but a
multi-scale superposition of soon-becominig-past and unresolved future
possibilities.
Turbulent: turbulence happens at all scales.
High-dimensional chaos.
Very high-dimensional chaos, if we imagine space to be a planck-scale grid,
with each grid-point holding some Boltzmann distribution of matter.
Chaotic, ergodic from somewhere around that scale, up to some microscopic,
millisecond scale in conventional experienced reality (longer time scales
for quantum experiments conducted in a lab, in a vacuum, etc.)
\end_layout
\begin_layout Standard
And this all sounds entirely plausible, to me, at least, but for one little
thing: Minkowski space.
Time dilation happens.
When I was a grad student in 1988, I took a mandatory lab course, and measured
the lifetime of a relativistic muon.
We had some mini-accelerator, and you could dial up the speed, and yes,
it took longer to decay.
Graph this on a chart, and the intercept with the y-axis, where the muon
is not moving at all, gives you the muon lifetime in the lab frame.
We have almost one hundred years of relativistic quantum experience behind
us.
Its true, it holds.
\end_layout
\begin_layout Standard
It holds at the non-relativistic scales, too: put an atomic clock on an
airplane, fly around, the passenger arrives some microseconds younger.
And this is the part where the vision of here-and-now as a frothy time-front
collides with Minkowski space.
It is what kept me awake, and didn't let me fall asleep.
I originally wanted to think about what happens when here-and-now falls
through an event horizon, but no, we already have conceptual difficulties
in Minkowski space.
\end_layout
\begin_layout Standard
The difficulty is this.
The airplane passenger does not arrive a few milliseconds in the future
from me, at the destination.
He arrives here, now.
You cannot hop on an airplane or a very fast rocket, use some binoculars
to peer out the window, and get a glimpse of the future:
\begin_inset Quotes eld
\end_inset
Hey Charlie, I'm in the future now, and I see this tiger jumping out of
the grass and eating you; you better run
\begin_inset Quotes erd
\end_inset
.
Well, of course not: the photons from the tiger arrive at light-speed:
the observer with the telescope is necessarily viewing past events.
Whose past? The observers past.
The observed events were, once upon a time, the present, for the observed.
\end_layout
\begin_layout Standard
I'm getting off track, this is all obvious.
But the paradox remains: the airplane traveller does not arrive in my future,
nor do I in his: when he stops moving and comes into my lab frame, our
clocks synchronize, and we both experience
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
, together, at the same time.
So what the fuck happened on the god-damned airplane, then? The airplane
passenger was in his own lab frame, and experienced time normally.
Specifically, he had an atomic clock, using quantum principles to measure
time.
Those principles are subject to the various quantum-speed-limit theorems
(Mandelstam 1940's, others, 1990's and 2010's, I wrote (re-wrote) almost
all of the Wikipedia article on quantum speed limits.
I understand this shit.
We're talking about time, here.) So we've got this clock on an airplane,
and it ...
goes slower.
In a very literal sense, because when the airplane lands, the present
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
in which we are trapped allows the passenger and I together agree that
his clock ran slower.
But, for him, everything ran slower: not just his clock, but everything:
his body, the plane itself.
His experiental reality of
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
moved slower as well, so that when he rejoins me in my lab frame, his
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
is exactly equal to mine.
Not just approximately, not just off by a few microseconds, but exactly.
\end_layout
\begin_layout Standard
Of course, here and now is at least a few microseconds thick, so there's
room for some slop.
Portions of
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
are ...
hours thick.
When I observe Jupiter, naked eye or telescope, I see
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
is it is (was?) on Jupiter, but that is 43 minutes away, plus or minus
nine minutes, depending on the relative positions of Earth and Jupiter.
So that is an entanglement: a quantum entanglement, because we are talking
about photons, this is not on the nanosecond time-scale, but on the hour
timescale.
And it really is
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
, because I cold shout out
\begin_inset Quotes eld
\end_inset
watch out, Jupiter! There is a tiger in the grass about to jump you! Oh,
wait, no, that's just comet Shoemaker-Levy.
Why didn't you get out of the way? Oh, you don't have a brain.
that's right.
That, and no way to propel yourself.
Jupiter, you literally have an IQ of zero.
\begin_inset Quotes erd
\end_inset
\end_layout
\begin_layout Standard
So the here and now of simultaneity extends up and down the light cone,
out to the age of the universe.
This is, again, well-known and obvious, and the geometry of null geodesics
is carefully described in umpteen textbooks.
And there are dozens more
\begin_inset Quotes eld
\end_inset
of courses
\begin_inset Quotes erd
\end_inset
.
So the problem is perhaps revealed, a tad:
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
is not a sharp line dividing future and past, but a boundary having thickness,
a few nanoseconds, when I talk about my feet, an hour, when I talk about
Jupiter.
\end_layout
\begin_layout Standard
I dunno.
This leaves me still not entirely satisfied.
I can't put my finger on it.
I'm on my third cup of coffee, its now an hour after I started writing
this essay, my head is still fuzzy and groggy, and all I know is that I
am not satisfied with some aspect of this conception of here-and-now.
I suspect that, even if I had slept a few hours longer, I would still be
unhappy about it.
And maybe no closer to a solution?
\end_layout
\begin_layout Standard
OK, so here's part of the problem.
When I talk about light, then obviously ...
well, lightcone.
But the problem was with the perception of time by the traveller.
Basically, the acknowledgement of
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
seems to cry out for some kind of ether, through which here-and-now passes,
like a wave.
This is NOT the same ether is that of the light wave (which we know doesn't
exist, Michelson-Morely, yadda yadda.) So that ether doesn't exist, but
the here-and-now seems to want its own kind of ether, through which my
lab frame propagates with unit proper speed.
And that's the conundrum: For massive matter, proper time moves with unit
speed.
Through what does time move? Well, now we can maybe? Finally? Perhaps step
back and talk about geometry? Does that solve any problems?
\end_layout
\begin_layout Standard
So the geometrical viewpoint is this: one says,
\begin_inset Quotes eld
\end_inset
a hah, spacetime is curved, and see here, geodesics are straight lines...
\begin_inset Quotes erd
\end_inset
Which is all fine and dandy, but you get into trouble, if you slap a coordinate
grid on spacetime, and attempt to say
\begin_inset Quotes eld
\end_inset
here and now is right here and now at coordinate (x,t) in that coordinate
system, ooh, wait, it moved, why here, now its over here, shifted by proper
time T, because you must understand, proper time advances at unit speed
in the lab frame.
So, fuck you: show me where
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
is, in your fucking coordinate system, and why it lines up for the guy
on the airplane, when his airplane lands, and his clocks resync with mine?
Where is
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
in flat-fucking Minkowski space, you puscillanimous puppy? Yeesh.
\end_layout
\begin_layout Standard
We start together, I say here and wait an hour.
You fly around in an airplane for exactly one hour and ...
what, you arrive a few microseconds in my future? Your clock ran slower?
That's your excuse? We are both in here and now, how come we can't agree
about how much time has elapsed?
\end_layout
\begin_layout Standard
So this, all these thoughts, this is what was going through my head, as
I was sleeping/not sleeping, tossing and turning.
And one more interesting thought shot in my head: perhaps, once we figure
out how to resolve the here-and-now problem, we might alight on a solution
for MOND in the galactic rotation curves.
Maybe it is here-and-now-ness that is causing the MOND-like effects.
The point is that the moving arms of a galaxy are moving, and so get time-dilat
ed.
Some hand-waving about Mach principle: the cosmic microwave background
CMB does provide an absolute reference frame.
We can crank through this, and see where it goes.
Its in chapter 7 or 8 of Ellis–Maartens–Maccullum Relativistic Cosmology,
yes, I've read that far.
I can't look up the page because I was reading in the browser tab and the
browser is down, but its like page 120 or page 150 or something, several
chapters into deriving stuff in comoving coordinate frames.
Should I take a break, start the browser, and properly download this time?
\end_layout
\begin_layout Standard
So anyway, we can do enough geometry to define comoving frames, and split
up all generalized FLRW type systems into explicit 3+1 forms, with assorted
shear tensors in there, and what not.
So there's an algebraic basis within which one can work.
Up to a point ...
\end_layout
\begin_layout Standard
See? I'm getting caught in the weeds, again.
Yes, of course, one can take the CMB and use it to define a space-like
surface, the surface of last scattering.
And then one can take this surface, and call it
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
and use it as a 3+1 coordinate frame, and then express all geometry with
respect to this coordinate frame.
As the Ellis etal book makes clear, there's a lot of terms in those 3+1
algebraic expressions; they're long, complicated and have unusual shear
and rotation terms in them if you are not accustomed to this, yet.
Fortunately, those terms vanish when you need them to, so everything is
all good.
So comoving coordinates do provide a kind-of-ish here-and-now reference
frame, for cosmological calculations.
And that's great! But it still doesn't explain what happened to the clock
on the airplane.
Why here-and-now clock-skews during the air-travel trip.
\end_layout
\begin_layout Standard
Or perhaps it does? Perhaps I should stick the path of the airplane into
the comoving coordinate system and get ...
get what, precisely? A big fumble of equations, that tell me, what? That
there's Lorentz time dilation? I don't need a big fumble of equations to
do that.
I already know there's time dilation, I just can't ...
put my finger on it.
\end_layout
\begin_layout Standard
Maybe the airplane trip is MOND-in-minature? The guy on the airplane flew
in a circle...
our clocks do not agree, our conception of here and now does agree.
Our clocks are quantum devices, quantum is fully relativistic, the clock
on the airplane measures time in the airplane frame.
Which is no an inertial frame, but the acceleration effects can be ignored.
I think.
I assume.
If I were to be careful, I would calculate the acceleration effects, and
say
\begin_inset Quotes eld
\end_inset
a hah these are fully ignorable
\begin_inset Quotes erd
\end_inset
but I am lazy, and besides, someone else has done this, and if they were
not ignorable, then I would know about it because it would be in textbooks.
But I don't know about it, therefore, its ignorable.
Interesting chain of deduction, there.
Just saying it out loud; of course, people think like this all the time,
which is why they get so surprised when they find out they're wrong.
In the present case, though, I'm pretty sure I'm not wrong: the acceleration
effects on clock skew for the air-trip are negligible.
\end_layout
\begin_layout Standard
The airplane trip is macroscopic; can I gain anything by going microscopic?
I dunno.
I can put muons in an accelerator, and get relativistic time shifts.
Are there any other clocks I can accelerate to relativistic speeds? The
problem with quantum is that it doesn't not
\begin_inset Quotes eld
\end_inset
really
\begin_inset Quotes erd
\end_inset
experience
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
.
Maybe the quark-gluon plasma does? I mean, the muon clearly experiences
time, But the radioactive decay is exponential, not some sharp cliff.
That sort of suggests that the muon is confused about where
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
is, and it has a lot of leeway in deciding when to decay.
Of course this is a highly heretical description of decay; the point is
not to claim that this is how muons actually work, but to claim that
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
is very ambiguous at the quantum scale.
At the macro scale, we've got ergodic, chaotic dynamical systems with billions
of degrees of freedom: brains experience here and now.
Obviously.
It is not clear how much smaller one can get.
Bacteria, I suppose: look at what nature has done with white blood cells,
killer T-cells: the immune system is hunting down enemies in the blood
stream, and this is very much a here-and-now experience for both the killer
T-cell, and the hunted bacterium.
It's the same as it was for the tiger in the grass.
\end_layout
\begin_layout Standard
How about viruses? We run into problems, and if we're not careful, talk
about panpsychism and integrated information theory.
Is
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
fundamentally observer-related, much like some of the Schroedingers-cat
arguments require brains to observe? Wigner's friend, and all that?
\end_layout
\begin_layout Standard
So this is where we bump into the wall of understanding how quantum interacts
with complex many-body systems, the so-called thermodynamic baths and whatnot.
The hand-waving is that a quantum measurement collapses upon interaction
with a many-body system, but I think I've spilled plenty-enough bytes on
this topic, earlier in the dirary, with no satisfactory resolution.
\end_layout
\begin_layout Standard
I did read about some Japanese(?) researcher who recently took some gas
of sodium or cesium or something at 500 degrees Kelvin, and was able to
observe thousands of entanglement interactions for the next millisecond.
That is, some entagled state is prepared, and then the system is released,
and then, for the next thousand atom collisions in this hot case, the entanglem
ent is passed off from one atom to another.
It is not erased upon the first collision, it is not erased in the first
ten collisions, it takes many, many collisions before it finally thermalizes.
So this is interesting: it confirms that ...
that ...
what? I don't know, because I read about this on some pop-sci newsite,
which, as per usual, garbles whatever the actual physics is occurring.
And I didn't read the paper in the original cause god knows I have enough
to do, and enough ADHD to not do it in.
\end_layout
\begin_layout Standard
So...
is the here-and-now problem somehow synonymous with the quantum-collapse
problem? I mean, ts obvious that large systems, the kind of systems that
biological evolution works with, experience here-and-now.
It's not obvious that non-conscious, non-living things experience here-and-now.
Well, sort of.
The riverbanks of a raging river do appear to experience here-and-now.
Erosion is real.
Erosion is thermodynamically irreversible.
\end_layout
\begin_layout Standard
So is here-and-now something to do with thermodynamic irreversibloty? Possibly
...
probably.
But we still have the Minkowski-space relativistic clock skew issue, and
I don't know how to formulate relativistic microcanonical ensembles.
I mean, yes, I can do a relativistic gas: I can look it up in a textbook.
I know which textbook too: relativistic gases are standard material for
cosmologists.
But a relativistic gas is not the same thing as airplane-ride clock skew.
The killer T-white blood cells are experiencing Loerentz time dilation
along with everything else on that airplane.
The thermodynamic irreversibility is proceeding apace as the stewardess
mixes a rum and coke.
The rum-n-coke gets Lorentz time-dilated, too.
How does the atomic clock work? Well, its got some Cesium, and some electronics...
\end_layout
\begin_layout Standard
The point here is that the thermodynamic
\begin_inset Quotes eld
\end_inset
increase of entropy
\begin_inset Quotes erd
\end_inset
is happening at the same speed as the clocks are measuring on the airplane.
At least, that is what one is urged to conclude, based on conventional
textbook teaching.
I mean, Einstein himself tells us that classical mechanics on a speeding
train works the same way as it does non a stationary train, and, by extension,
so does thermodynamics.
As far as I know, no one has done any experiments to confirm that rum-and-coke
on an airplane mixes just as rapidly as it does in the airport lounge.
But it would be insane to think that thermodynamics worked differently,
because you would think that if it did, it would manifest in some obvious
fashion.
No.
We must take as a given that thermodynamics is fully invariant, covarient,
whatever word you want to use: thermodynamics feels proper time in the
lab frame.
\end_layout
\begin_layout Standard
See? So we keep getting fucked, over and over again.
A buddy standing next to me gets on an airplane, creates some entropy there,
arrives with his entropy which is now a few microseconds younger than my
entropy, but were are both in the here and now.
And his clock was a quantum clock that collapsed it's wave functions in
a fully covariant relativistic way, because otherwise his clock would ...
have worked differently? ??? And there's no reason to beleive it works
differently, and there's nothing to grab hold of here, that could be formulated
into an experiment that might plausibly give results that differ from textbook
predictions.
The Bell test proved entanglement.
I do not have the analog of a Bell-test for here and now.
\end_layout
\begin_layout Standard
Hmm.
How about interferometers? Can I build some interferometer experiment,
where one arm is in
\begin_inset Quotes eld
\end_inset
the lab frame
\begin_inset Quotes erd
\end_inset
, and the other arm is somehow
\begin_inset Quotes eld
\end_inset
Lorentz-contracted
\begin_inset Quotes erd
\end_inset
? Ooof.
Suppose I could build such a device, what would I learn? The analysis is
difficult.
Interferometers conventionally use light.
I guess I would need a mater interferometer.
Say, a neutron interferometer.
But we already know that gravity works correctly with neutron interferometers,
one does have a gravitational Bohm-Aharonov effect going on there.
I have to thank Frank Yang for that: the one class at Stony Brook that
he did teach was filled with these non-conventional off-the-wall type topics.
He wasn't working off a textbook.
He was working with all the strange and bemusing marvels that tickled the
intellect, like having neutron waves that felt gravitation.
Phase difference of exp(i(mgh)t) or whatever.
How might I create a
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
interferometer? Send two bacteria on two different paths?
\end_layout
\begin_layout Standard
Again, what is the largest clock I can accelerate to relativistic speeds?
I don't mean some large nucleus with some beta decay mode.
Yes, that is clock-like, but its not thermodynamic.
..
Stop.
I already concluded from the airplane trip that, even if I could get a
large, thermodynamic-scale, Avogadro's-number size clock accelerated to
relativistic speeds, it would behave exactly as Lorentz would expect.
So where the fuck is here-and-now happening? I'm fucking completely stumped.
\end_layout
\begin_layout Subsection*
6 February 2025 Evening
\end_layout
\begin_layout Standard
Twelve hours later.
I did something else till I got fried, Started reading Ellis et all again,
finished chapter 5 (matter), skimmed chapter 4 (kinematics) again, and
came back to here.
The bonk I'm having is that here-and-now is not a coordinate (kinematic)
problem, its a dynamic problem.
There's no problem whatsoever o laying down a coordinate system on Minkowski
space, and of expressing the proper time for any inertial observer whatsoever.
We can label however we want, there's no confusion or ambiguity.
\end_layout
\begin_layout Standard
One can do even better: one can sprinkle the space with smart dust: these
are inertial radio transmitters, each broadcasting, via radio waves at
a given (fixed) frequency), their unique ID number, their proper time (as
carried by an onboard clock) and the broadcast is encoded with directional
beam data.
Thus, you as an observer, can receive this data: from redshifts, you know
how fast they are moving.
You can double-check this by looking at the timestamp they encoded; this
should be 100% identical to the redshift.
You can determine transverse motion, because the beam-direction encoding
is changing, which is again identical to where you see them.
You can determine distance by measuring signal power (brightness).
All motion is purely kinematic, all data should be 100% consistent with
whatever calculations you make for the trajectories in your chosen coordinate
system.
For each and every transmitter, you can say with absolute confidence where
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
was, and will be (because there is no interaction (other than sending/receiving
data), and the dynamics is trivial – just free particle motion.)
\end_layout
\begin_layout Standard
In this picture, we get a
\begin_inset Quotes eld
\end_inset
timeless
\begin_inset Quotes erd
\end_inset
picture of Minkowski space: were know where everything was, and where everythin
g will be, and when it was, and when it wiil be, for you, and for any transmitte
r.
\end_layout
\begin_layout Standard
The problem is to reconcile this timeless vision, with the idea that, for
any given transmitter, the future has not yet happened.
By the time you receive a signal from them, you know where they were, then,
because the always transmit
\begin_inset Quotes eld
\end_inset
right now
\begin_inset Quotes erd
\end_inset
, by definition.
Everything you receive is in your past light cone.
You can predict (with perfect accuracy) what you will receive, in the future.
The
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
clock ticks independently for each and every transmitter: They don't need
to have been synchronized in the past.
They do need to agree on frequency; as otherwise, you cant tell who is
redshifting or not, although I guess you can track change in received power.
\end_layout
\begin_layout Standard
So, when I receive a signal, right now, I know it was sent,
\begin_inset Quotes eld
\end_inset
right then
\begin_inset Quotes erd
\end_inset
, bu the sender.
If a transmitter is coming straight at me, I know it will be
\begin_inset Quotes eld
\end_inset
right now
\begin_inset Quotes erd
\end_inset
exactly when they pass by, because I will receive the signal, immediately,
as they send it, and we will both be sharing that
\begin_inset Quotes eld
\end_inset
right now
\begin_inset Quotes erd
\end_inset
moment together.
This will occur because our worldlines intersect, and when they intersect,
it will be
\begin_inset Quotes eld
\end_inset
right now
\begin_inset Quotes erd
\end_inset
for both, and this will happen at the
\begin_inset Quotes eld
\end_inset
same place
\begin_inset Quotes erd
\end_inset
for both.
It cannot be any other way.
This is obvious, when put this way.
\end_layout
\begin_layout Standard
In this picture, there is no confusion about where
\begin_inset Quotes eld
\end_inset
right now
\begin_inset Quotes erd
\end_inset
is, and there is no magic synchronization of
\begin_inset Quotes eld
\end_inset
right now
\begin_inset Quotes erd
\end_inset
that is needed: it happens where needed, as needed, and it happens independentl
y of the observer.
Time marches along for each transmitter, independently of all other transmitter
s, and there is no need to coordinate about 'where' 'right now' is happening.
There is no magic coordinator of
\begin_inset Quotes eld
\end_inset
right now
\begin_inset Quotes erd
\end_inset
.
There is no need for one, and there's no paradox.
Right?
\end_layout
\begin_layout Standard
If there's no paradox, then why am I spending hours and hours confused about
something? What am I confused about? Why am I confused? I'm not dumb.
When I have been confused in the past, it was because I mis-understood
something, made some faulty assumption that was not true.
Upon fixing the mistake, the confusion evaporates.
In the present case, what is the faulty assumption that I am making? What
lies at the root cause of my confusion?

Went to bed at midnight.
By 7AM the answer to the above is in my mind.
The next question: should I get up now, or go back to sleep?
\end_layout
\begin_layout Standard
The basic confusion is between mathematics, physics, postulates and observation.
In mathematics, we have the ability to write down pseudo-Riemannian spaces,
with metric, in arbitrary m+n dimensions, and everything
\begin_inset Quotes eld
\end_inset
just works
\begin_inset Quotes erd
\end_inset
.
Lots of well-developed tools and techniques.
Observationally, we know that we live in a locally flat 3+1 space, and
even cosmologically so.
There's a question: why is is it 3+1 instead of some other m+n? But that
is not what we're trying to ask.
\end_layout
\begin_layout Standard
So now we have physics, and postulates.
We can postulate: in a 3+1 flat Minkowski space, clocks moving along paths
behave exactly as the mathematical machinery should predict they do, and
we know that the mathematical machinery is self-consistent and complete
and paradox-free.
We postulate this as the correct answer, because we have oodles of observationa
l experience indicating that this is the correct answer.
Once this is accepted as a postulate, then there is no paradox.
The physics (perhaps its meta-physics?) is
\begin_inset Quotes eld
\end_inset
sure, but what if I don't postulate that answer? Can I derive it from other
principles?
\begin_inset Quotes erd
\end_inset
\end_layout
\begin_layout Standard
Or perhaps it is something simpler: a Newtonian rebellion.
Conventional experience is so firmly rooted in a Cartesian 3D world with
one linear time dimension that the malleability of time is a counterintuitive
surprise.
I can either throw up my hands and say
\begin_inset Quotes eld
\end_inset
yeah, whatever, this is just the way time works
\begin_inset Quotes erd
\end_inset
and move on to something else, or I can continue to bang my head on a wall,
and ask,
\begin_inset Quotes eld
\end_inset
but why does time work like that?
\begin_inset Quotes erd
\end_inset
\end_layout
\begin_layout Standard
The difficulty with the second approach are the mathematical tools, again.
Our tools work in any m+n dimensions.
We can write down any classical field theories in m+n.
These theories will have many–body statistical mechanics that is fully
compatible and consistent in m+n dimensions.
We can even quantize most of these field theories.
We can of course do this for n=0 and taking a distinct Newtonian time for
the differential eqns and the (measure–preserving) dynamical systems.
And this is all consistent.
So it would seem that there's nothing in stat mech or QM that we can look
at, employ or use to determine the underlying causal structure of spacetime.
Those theories all take causal structure as
\begin_inset Quotes eld
\end_inset
input
\begin_inset Quotes erd
\end_inset
, they do not generate causal structure as
\begin_inset Quotes eld
\end_inset
output
\begin_inset Quotes erd
\end_inset
.
\end_layout
\begin_layout Standard
The closest that we come to having something that can have causal structure
as output is the classical Einstein–Hilbert action.
But even that is a cheat: it already assumes 3+1 as the microscopic, local
tangent space, and only turns the metric into a dynamical variable, and
asks to solve for the metric.
\end_layout
\begin_layout Standard
I am not asking to turn 3+1 into a dynamical variable, perhaps because I
don't know how to make integers dynamic.
Or perhaps I do? There's all this fractal Hausdorff–dimension stuff and
so maybe, just maybe, one could instead start with some measure-preserving
dynamical system with structures having a variety of fractional dimensions,
and write down some kind of action for that, and then discover that this
action is minimized when most or almost all structures have a 3+1 Hausdorff
dimension.
Something along those lines.
\end_layout
\begin_layout Standard
Is this what I'm looking for? Secretly imagining? Is Terrence McKenna right
in saying there's a little radio receiver in my mind, listening to whispers
from the universe as to what the physics of it is? These intuitive, creative
insights really do seem to come from somewhere else.
Well, of course, they do: they come from the non-verbal subconscious mind,
and the verbal mind gets surprised: where the fuck did that come from?
It must be God speaking to me, or the Universe, or little magic molecules
that live in mushrooms, in the case of Terrence McKenna.
Of course, all of this is wrong: the creative insights are just coming
from another part of your brain that is not your verbal centers.
And your verbal centers are sufficiently detached that they get surprised.
\end_layout
\begin_layout Standard
So this is a good time to relate another strange thing that happened.
As I slept and dreamt last night, in one of my dreams, I was reading a
software review.
It was comparing a number of different software systems, including the
AtomSpace.
The review was making some fairly deep theoretical insights, and the conscious
I, the lucid observer, struggled to determine if these statements were
true.
That is, the dream had these words, these sentences.
The lucid dreamer was trying to check if the words were saying something
true.
It was challenging.
For a while, me, the lucid dreamer, kept trying to put the dream on slow–mo,
to pause the dream, so I would have more time to determine the accuracy
of the statements therein.
But as you may know, pausing a dream is hard.
One can, sort–of–ish do this, slow it down, prevent the dream narrative
from advancing so rapidly, but this is not easy.
So after a while, I have to give up on this, and so I am hearing this verbal
stream making complex technical assertions, and the lucid me is doing this
\begin_inset Quotes eld
\end_inset
sounds about right
\begin_inset Quotes erd
\end_inset
but I can't keep up.
So its like a college class or a lecture where the speaker is going a bit
faster than your comprehension, so you can't quite keep up.
And so the lucid me is marvelling a bit: how the fuck is the dreaming me
coming up with these words, that seem to be expressing complex ideas that
are more or less technically correct? I mean, me, I, consciously–aware
I, am here, experiencing the dream, and in that dream, there is some text
that I am reading/hearing, and that text is from not-me, its from the backgroun
d texture of the dream.
How did it get so technically accurate? It's quite the surprise.
In conscious, waking life, it is 'me', the self–aware me, that is always
with me, indivorceable, and it is that me that does all the thinking.
So it is a surprise when there is something 'other than me' that is getting
things right.
So, I know I'm dreaming, so I know this is all in my own skull, so the
surprise is that there's some part of my brain, that is not part of lucid-me,
that is capable of generating accurate verbal synopsis of difficult abstract
concepts.
Wow! Lucid me was surprised! Lucid me is used to it's kingly authority
as the fount of all consequential thought and action.
There's a part of my brain, detached from self-aware me, that appears to
be capable of verbalizing complex ideas.
Very interesting.
\end_layout
\begin_layout Standard
Now that I'm awake, I can rationalize, and say, perhaps this should not
be a surprise.
Some of my lucid dreams have these incredible photorealistic landscapes
(I love those dreams!) where any direction I look out on, I see things
is sharp, clear focused detail: fields and forests and clouds, in impeccable,
rich colorful detail.
And lucid me never stops to wonder
\begin_inset Quotes eld
\end_inset
hey wait, where did these fantastic images come from?
\begin_inset Quotes erd
\end_inset
Maybe because fully–awake me is already quite distantly removed from my
imaging system.
Certainly, my direct visual system is entirely out of conscious control.
I cannot will myself into seeing thing that are not there.
And if I close my eyes, and try to imagine a landscape, I can do so only
poorly, getting only a vague image (that psych test, one to five, of visualizin
g an apple, when someone says apple.
Hmm.
Wait.
OK, so that's false, I am having no problem at all visualizing a clear
precise, visually detailed apple.
More accurately, I am having a clear, detailed precise vision of the psych-test
image, and of the twitter post it appears on.
And I can do this without closing my eyes: I see the twitter screen in
great visual detail.
I could draw it, pen and paper.
Well, of course, that twitter thread was stupid.
Any and every fine–arts student has the ability to snapshot and hold a
visual image in their head, because this is a basic talent you must posses,
if you are going to move paintbrush on canvas.
So there is conscious control over imaginative imagery.
It's just that the imagery is not a part of verbal me, it is outside of
verbal, narrative me.
It is clearly
\begin_inset Quotes eld
\end_inset
in my head
\begin_inset Quotes erd
\end_inset
, where I can access it.
But it is not I.
The image does not proclaim,
\begin_inset Quotes eld
\end_inset
I am you! I'm in charge here! I am king and rule over this entire mental
domain!
\begin_inset Quotes erd
\end_inset
No, the mental image just sits there passively, presenting itself to the
king of conscious awareness.
The verbal centers are much closer to the king; like the court jester,
constantly whispering into the king's conscious awareness.
The closest advisor.
Of course, I have to sometimes tell mister verbalize to shut up and go
away, because symbolic abstract thought is not verbal.
But clearly, as I write these words right now, verbality is primal.
Perhaps not in charge, verbality is being used as a tool by conscious me
to express the things I, err, uhh, feel like expressing right now.
So, when I think abstractly, I do NOT do it in words.
and if I was a fine artist, a painter sculptor, and spent many hours a
day, many days a year painting and drawing and sculpting, then perhaps
visual image abilities would have a primacy stronger and more powerful
than verbal.
But I am not ..
drawing an painting hours a day.
I am ...
writing hours a day.
I am doing abstract math, hours a day.
I am writing abstract software, hours a day.
And I am getting physical exercise, hours a day.
So these things are primal.
\end_layout
\begin_layout Standard
I also wanted to mention tulpas, at this point.
There is a central, self–aware me, and the above paragraphs make it clear
that I have all these various talents and abilities that are not self-aware.
They are inside my brain, they live next to my conscious experience, but
they are not conscious, self-aware in and of themselves.
The mental image of clouds drifting across a sun-speckled sky is not proclaimin
g self-awareness.
Only I do that.
And so, in this sense, I am compartmentalized: self-aware me can pass out,
fall asleep, without damaging the visual centers, the athletic centers,
the verbal centers.
Those centers function, function next to me, a part of me, but they are
not self-aware of me, the way that I am.
Very curious.
\end_layout
\begin_layout Standard
Why do I write this stuff? This is surely spelled out in great detail in
a zillion psychology texts.
And before that, perhaps great authors of fiction have already presented
such analysis in some long novel I have not read.
I guess I could say
\begin_inset Quotes eld
\end_inset
these are my thoughts.
There are many others like them, but these are mine.
\begin_inset Quotes erd
\end_inset
\end_layout
\begin_layout Standard
Well, I think I've exhausted the psychological angle.
Back to physics, maybe? Or am I exhausted?
\end_layout
\begin_layout Standard
Where were we? Frothy here-and-now.
The tools I have available to me are these: the conventional tools of different
ial eqns, which encourage analysis in terms of points x which move about.
Then there's pointless topology: frames and locales, which show you how
to do topology without points.
Somewhere I have a PDF called
\begin_inset Quotes eld
\end_inset
Topological Field Theory
\begin_inset Quotes erd
\end_inset
I think its a book, or maybe just a very long paper.
I have not read it yet.
Maybe it's time I did.
The idea here is that measure theory and ergodic theory is a tool that
allows working with things that are not points.
So I know how to define a measure–preserving dynamical system; I wrote
almost all of the Wikipedia article on that topic.
What I do not know is how to endow a measure–preserving dynamical system
with the geometry of a manifold.
\end_layout
\begin_layout Standard
And that is a very good point.
I'm deeply conversant with these two quite different mathematical languages.
But oddly, I do not understand even the smallest thing about how to hook
them together! I do not know how to take some dynamical system, and say
\begin_inset Quotes eld
\end_inset
le voila! here is how one constructs the tangent space for this system.
\begin_inset Quotes erd
\end_inset
If there's some symplectic structure, it was always there, from the beginning,
built into the dynamics.
I never start with dynamics, and then later discover what it's symplectic
structure is.
Hmm.
\end_layout
\begin_layout Standard
I cannot even think of the most basic example of this.
Say, some process taking place on some lattice, and I deduce some geometric
structure from it.
I guess there's something that comes close: AdS-CFT where you start
\begin_inset Quotes eld
\end_inset
here
\begin_inset Quotes erd
\end_inset
and fall out
\begin_inset Quotes eld
\end_inset
there
\begin_inset Quotes erd
\end_inset
.
But that's already quite ....
I mean, CFT is already geometrical, to start with, so finding something
else geometrical (like AdS) is cool, but not the topic.
Can I start with something non-geometrical, but with something that is
dynamical, and then find that this dynamical system has a geometry? The
holy grail would be to find that the geometry is 3+1.
\end_layout
\begin_layout Standard
I dunno.
I've wasted enough time, here.
I think I'm done for now.
I should recap, before closing shop.
There is a frothy here-and-now that advances as a boundary between past
and future.
Observationally, this boundary moves in a fashion that the past has (more
or less) the geometric structure of a metric manifold, the pseudo–Riemannian
manifold of GR spacetime, and the fields upon it.
The mathematical tools I currently have access to do not explain why its
3+1, why it stays 3+1, why its metric, why its flat, and why its Minkowski.
These are observational facts, not theoretical deductions.
Time in special relativity is quite counter–intuitive.
In my mind, I can imagine a frothy here–and–now wavefront, but my imagination
wants it to be Cartesian, Newtonian.
I can now accede that, sure, this frothy front can be made to froth along
in Minkowski space just fine.
The froth travels with speed exactly one – the proper time in any reference
frame measures the speed of the froth in that frame, and all special–relativist
ic, Lorentz-contract motions for this froth front are fully consistent.
We are forced to concede that
\begin_inset Quotes eld
\end_inset
time is weird
\begin_inset Quotes erd
\end_inset
, and to live with that.
The only way to make time not weird is to insist
\begin_inset Quotes eld
\end_inset
time is not weird, you silly goose, you just don't understand special relativity
\begin_inset Quotes erd
\end_inset
but that is a very thuggish statement.
Right up there with
\begin_inset Quotes eld
\end_inset
give me your wallet.
\begin_inset Quotes erd
\end_inset
Insisting is not a very good way of doing physics.
But, for now, there do not seem to be any other avenues.
Time is proper time, sorry, Charlie, deal with it.
Your froth–front is special–relativistic, and more: its general–relativistic.
You have both tools and computer codes that do this: you can do supernova
on supercomputer simulations, and get all the statistical mechanics right.
It all works.
Shut up and calculate.
For my case, its
\begin_inset Quotes eld

\begin_layout Standard
So I've resolved some dazed–and–confused paradox by sort of saying
\begin_inset Quotes eld

While sleeping, I realized that cosmic inflation ...
well of course it flattens the universe, but it also synchronizes
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
across the entire horizon.
The entire visible universe has the same
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
, to a flatness at the same scale as provided by inflation (so, much much
flatter than CMB).
In particular, the above resolved paradox implies that
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
is not distorted by (dark) matter, because
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
is always happening in proper time.
Intervening matter might make clocks run slower for some observers, compared
to others, but there is no shear; when two observers rejoin, their
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
will agree.
That is,
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
is synchronized for all comoving coordinates, and even more strongly: it
is synchronized on the spacelike surface at which inflation ends.
\end_layout
\begin_layout Standard
This raises several conceptual issues.
First: is
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
a property of spacetime itself, or does it require additional fields? Does
it require few-particle quantum? Does it require statistical many-body
quantum? Is it a property of the quantum vacuum? Earlier thoughts on the
thickness of
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
implies that it is necessarily a problem of revising causal (quantum) interacti
ons between different parts of spacetime.
Thus, frothy-now is, at this level, something that happens in the presence
of normal matter.
I have not considered if froth is a property of the quantum vacuum.
I suppose it should be, but given that I have almost nothing to grasp hold
of, who knows.
\end_layout
\begin_layout Standard
A second question is
\begin_inset Quotes eld
\end_inset
what would happen if two observers, experiencing different 'now', were to
meet?
\begin_inset Quotes erd
\end_inset
This is more or less unanswerable, since cosmic inflation guarantees that
everything in the visible universe has the same 'now'.
I cannot run that experiment.
\end_layout
\begin_layout Standard
The paradox still bugs the shit out of me.
Lets see if we can make forward progress.
So, at the end of inflation, we have a space-like surface that is flat
by virtue of inflation.
It is unique, in the sense that one could pick other space-like surfaces,
but those would have points that are in the future from the end of inflation.
That is, there is only one space-like surface, on which the proper-time
distance to the end of inflation is zero.

This unique surface defines a Newtonian frame.
Every point on that surface has exactly one unique perpendicular time-like
vector.
By axiom, by assumption, we say that 'now' starts synchronized on this
surface.
Perhaps it has some finite thickness already, and so we must talk about
the mean, average 'now' on this surface.
But at the moment, nothing is lost by assuming it is precisely sharp and
free of shear and vorticity.
\end_layout
\begin_layout Standard
This gives us a unique, and very Newtonian definition of 'now' for the future
of the universe.
Starting at that surface, integrate the perpendicular proper-time vectors.
This gives a single unique vector field flow, for all points in the spacetime
of the universe.
By hypothesis, the location of 'now' is the slice (section) at fixed proper
time since the end of inflation.
This slice is a surface, since, by hypothesis, there is no vorticity in
the initial conditions.
\end_layout
\begin_layout Standard
This is very odd to me.
It appears to be a way of defining a unique quasi-Newtonian coordinate
system up the entire universe.
My book on relativistic cosmology almost says this, but not quite.
In chapter 4, it sets up the kinematics of comoving coordinates.
It says
\begin_inset Quotes eld
\end_inset
pick a spacelike surface
\begin_inset Quotes erd
\end_inset
but it doesn't say how.
It makes the vague implication that this is in the early universe.
Since the chapter is on kinematics, of course, it should not say how: kinematic
s is about developing tools.
It then allows you to pick observers on that surface.
The observers that you are allowed to pick do not need to be moving orthogonal
to that surface.
So, if you follow the flow lines of those observers, you will find, in
general, some shear and some vorticity.
This allows a purely kinematical derivation of the generalized Hubble relation,
on page 81.
And that is fine and well.
I'm not adding some minimal dynamics: pick the spacelike surface to be
the one at the end of inflation, *and also* pick observers orthogonal to
that surface.
Thus, by definition, both shear and vorticity are set to zero, for
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
.
\end_layout
\begin_layout Standard
And so we kick things off.
Let the universe evolve.
Allow particles of matter, subject to forces and pressures, do their thing.
Most of these will not be moving on geodesics, because they are subject
to forces and pressures: i.e.
not dust.
Pick two observers, carrying their proper-time locks with them.
Allow them to be buffeted by forces and pressures.
Assume that they meet one-another at some future space-time point.
At that point their clocks will have different readings: each will have
experienced a different rate of flow of time.
However, when they meet, the 'now' of their meeting has to be identical.
\end_layout
\begin_layout Standard
I know this, because that experiment can be performed: my buddy flies around
in an airplane with his clock, and he arrives back home a few microseconds
younger, but his experience of
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
is the same as my experience of
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
, and is not off by a few microseconds.
When the tiger jumps out of the grass to eat us, he does not have a few
microseconds advantage at predicting the tiger-jump.
\end_layout
\begin_layout Standard
Well, let's look at this more carefully.
He and I both predict the tiger-jump based on sight and sound.
Lets stick to sight, i.e.
photons, i.e.
the light-cone.
he and I are getting the same info at the same time about the tiger, because
both of us are equally distant from the tiger, and neither of us are moving
with respect to one-another, and thus do not have some advantage from the
simultanaity ordering of space-like separated events.
We both get the same information about the tiger at the same time, irrespective
of earlier changes to our clocks.
Thus, we necessarily experience the same 'now'.
\end_layout
\begin_layout Standard
This paradox is stubborn.
So imagine a third observer.
They start out at time t=0 at the surface of the end of inflation.
The are orthogonal to that surface, and then they ignore all forces and
pressures, so as to move on a geodesic from that point onwards.
Lets assume that matter is uniformly dispersed, so that there is no lumpiness
that would make gravitation bend up the spacetime: i.e.
that we can ignore the effects of gravitation on this observer, so that
his geodesic is effectively a flat-Minkowski-space geodesic.
This third observer arrives at the point where my buddy and I are having
a little problem with the tiger, and what does he see? Why exactly what
we see: All three of us are equi-distant from the tiger, all three of us
are stationary with respect to one-another.
All three of us are effectively at the same point in space, moving together,
and all three of use get to experience the future based on the sommon arrival
of the same signals from the tiger.
All three of use experience the same
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
.
This is completely independent of any Lorentz contractions that may have
been experienced in the past.
\end_layout
\begin_layout Standard
So it seems that
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
always travels with the observer, and that
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
always moves with unit speed of proper time, so that
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
is always measured by the clock that the observer carries.
But when different observers arrive at the same place, their
\begin_inset Quotes eld
\end_inset
nows
\begin_inset Quotes erd
\end_inset
coincide, even though their clocks do not.
That is the paradox.
That is,
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
is always measured by clocks.
But also, now is always equal, an equality relation, for observers at the
same point on the spacetime manifold.
That is, every point on the spacetime manifold has one and only one
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
, unique for that point.
All observers arriving at that point get the same
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
, even though they have experiences a different history of spacetime paths.
\end_layout
\begin_layout Standard
Formulated this way,
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
is a kind of equivalence relation between paths.
So this is homotopy
\begin_inset Quotes eld
\end_inset
upside-down
\begin_inset Quotes erd
\end_inset
.
We start by saying there are many (time-like) paths, but when those paths
intersect at a point, those paths necessarily all have the same
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
at that point.
This defines an equality relation for those paths.
All equality relations induce a quotient topology, In this case, we take
the Cartesian product of all paths, modulo equality when those paths intersect.
\end_layout
\begin_layout Standard
Of course, this is quasi-incoherent, because, by convention, to define a
path, we have to first define an underlying manifold on which the path
is taking place.
At least, that has always been my understanding of books on algebraic topology.
Absolutely none of them say
\begin_inset Quotes eld
\end_inset
imagine a bunch of paths, now imagine the paths intersect, now imagine the
points at which they intersect form a manifold
\begin_inset Quotes erd
\end_inset
.
Even in the intermediate parts of the book, where snake lemmas are being
presented, I don't think you can go back and say
\begin_inset Quotes eld
\end_inset
see, earlier in this snake, to the left of this snake, there's not yet a
manifold of points, there is just a manifold of paths
\begin_inset Quotes erd
\end_inset
.
I dunno.
Maybe you can? But its always about exact and closed operators, and they
have to be exactly and closed on ..
something ...
and that
\begin_inset Quotes eld
\end_inset
something
\begin_inset Quotes erd
\end_inset
has to be a space on which paths have been defined.
Right? Jeez, I would have to re-read all of these books, and rethink this,
fro scratch, to see if somehow, underlying manifolds can be discarded at
each step, and higher spaces be built up as quotients of collections of
paths with equivalence relations defining what the same point is.
\end_layout
\begin_layout Standard
I wonder if some professor would have explain this, if I'd learned this
in a class, instead of a book.
But the books did not breath a sigh of this.
I might have been a sloppy reader, but I swear, none of them say this.
None of them say
\begin_inset Quotes eld
\end_inset
start with a collection of paths and *define* a collection of points as
an equivalence relation on the paths
\begin_inset Quotes erd
\end_inset
.
Why don't they do this? Because they would need to somehow define what
a
\begin_inset Quotes eld
\end_inset
path
\begin_inset Quotes erd
\end_inset
is, without making reference to some underlying manifold.
And they would need to define an equivalence relation, of being at the
same place/point, without reference to the underlying manifold.
And, just right now, it seems a bit incoherent to try to do this.
Its not clear how it could be possible to do this.
Hold that thought.
I'm going to git commit right now.

Jeez Louise, my thoughts keep getting farther and farther out there.
My apologies to you, dear reader, who does not exist.

\end_layout
\begin_layout Standard
OK, so here's the deal.
In my conception of algebraic, computer-scientific parsing, I have these
jigsaw pieces.
Such as those in Link Grammar.
I did not invent these; they have a long storied existence in math and
appear and reappear in varied guises in varied contexts.
\end_layout
\begin_layout Standard
So now, lets take these as a given.
This jigsaw pieces exist
\begin_inset Quotes eld
\end_inset
fundamentally
\begin_inset Quotes erd
\end_inset
outside of any manifold or structure or spatial setting.
They are not objects in any conventional space.
I can have collections of them, so I can shove them into a set, or talk
about sets of jigsaws.
\end_layout
\begin_layout Standard
The connectors on each jigsaw are potentialities.
They are connections that could be made, but have not been made, yet.
\end_layout
\begin_layout Standard
The brain-storm here is both deep and shallow, as brainstorms are: I can
construct a causal spacetime out of jigsaws.
Now that I think about it, I imagine that some clever professor, maybe
Smolin or someone, has already done this.
And maybe even a few decades ago, or more.
But still, whatever, I am not going to go on a literature search, until
I can first make this idea more precise.
Do it in stages.
\end_layout
\begin_layout Standard
At the first stage, we have a collection of jigsaws.
A set.
They have two multi-connectors: one past-pointing, and one future pointing.
A link-grammar multi-connector is just a connector that can have zero or
more connections, there is no constraint on the number of connections that
can be made.
For the current scenario, an uncountable infinity of connections must be
allowed.
This is because any given point in spacetime may have an uncountable number
of connections into the past causal cone.
\end_layout
\begin_layout Standard
Well, I guess I should have said this up front: these jigsaws are going
to be the points of space-time.
That is, the starting point is a collection of points, but no topology
has yet been defined.
The goal is to eventually define a topology.
By the word
\begin_inset Quotes eld
\end_inset
topology
\begin_inset Quotes erd
\end_inset
, I am now imaging the conventional definition, as given in conventional
textbooks on general topology.
The difference is that I am not starting with structureless points, and
arranging them into
\begin_inset Formula $T_{0}$
\end_inset
,
\begin_inset Formula $T_{1}$
\end_inset
,
\begin_inset Formula $T_{2}$
\end_inset
separation axioms.
Instead, I am given each point a collection of connectors, and the potentiality
of connecting those connectors will result in the separation axioms (so
\begin_inset Formula $T_{2}$
\end_inset
here is Hausdorff, as per convention).
I am very tempted to just drop everything right now, go crack open a textbook
on topology, and start writing down *exactly* how separation axioms can
be converted into connectors! This would be a fucking excellent homework
problem! I guess it has to be done! This would be the goddamned first real,
actual activity: everything I've written in this diary so far has been
punching at smoke.
\end_layout
\begin_layout Standard
Cool! Drop everything, and do it! Strike while the iron is hot!
\end_layout
\begin_layout Standard
Slow your roll, there, bubba.
\end_layout
\begin_layout Standard
Lets assume that the separation axioms can be reformulated into connectors.
Somewhere in those texts, it becomes clear that metric spaces and normal
spaces and I forget what else they are called, are all the same thing:
they are spaces with nice properties.
The metric spaces in conventional texts on general topology all use positive–de
finite metrics.
I don not recall ever reading any textbook on general topology that had
any pseudo–Riemannian notions in it, but it is probably safe to assume
that such textbooks exist.
They will be obscure, because this does not enlighten the conventional
student of mathematics, for whom pseudo–Riemannian anything is far from
the mainstream.
Whatever, I wander off track.
\end_layout
\begin_layout Standard
So I want to define jigsaws with two multi–connectors: one future–pointing
and one past–pointing.
Now, this is where it gets interesting.
I am fairly sure that I do not need space–like connectors.
I think, I imagine, the hypothesis that Cartesian space will magically
appear, after stitching together the past and future connectors into a
cloth, into a rhizome.
The definition of spatial distance will be built out of a definition of
proper–time distance moving back and forward in an interferometric fashion.
That is, I will start at a point
\begin_inset Formula $p$
\end_inset
and move backwards in proper time
\begin_inset Formula $\Delta t$
\end_inset
along some connector (or connector–chain), arrive at some point
\begin_inset Formula $q$
\end_inset
in the causal past of
\begin_inset Formula $p$
\end_inset
.
Then I will pick a future–pointing connector on
\begin_inset Formula $q$
\end_inset
and walk forward a proper time
\begin_inset Formula $\Delta t$
\end_inset
to arrive at a point
\begin_inset Formula $r$
\end_inset
in the causal future of
\begin_inset Formula $q$
\end_inset
.
So both
\begin_inset Formula $p$
\end_inset
and
\begin_inset Formula $r$
\end_inset
are in the causal future of
\begin_inset Formula $q$
\end_inset
.
Then define the space–like distance between
\begin_inset Formula $p$
\end_inset
and
\begin_inset Formula $r$
\end_inset
to be some number that is necessarily smaller than
\begin_inset Formula $2\Delta t$
\end_inset
.
Presumably, one can now develop the conventional high–school/college conception
s of limits to take the limit
\begin_inset Formula $\Delta t\to0$
\end_inset
and obtain a definition of space–like separation between points on a pseudo–Rie
mannian manifold.
\end_layout
\begin_layout Standard
In this way, I can construct a pseudo–Riemannian metric out of thin air,
simply by working with points that have connectors on them.
I do need to have those connectors have an associated proper–time on them.
The connectors are explicitly tangent vectors.
\end_layout
\begin_layout Standard
So lets restate that construction: take a bunch of tangent spaces, and discard
the underlying manifold from which they came.
Discard also all space–like vectors.
Gut intuition is that we do need to keep the null–vectors.
So I now have an uncountable set of disjoint pairs of vector spaces: a
past–pointing vector space Cartesian–product–times a future–pointing vector
space.
Now I take steps to assemble, stitch these all together.
\end_layout
\begin_layout Standard
I'm not sure quite what formalism is to be used for stitching these together.
There are certainly well–developed formalisms that talk about creating
Lie groups from Lie algebras, and there are ways of defining the exp function
on Riemannian manifolds, but it is not clear to me if this puts the cart
before the horse.
That is, we do not yet have a manifold, so we do not yet have any pre–conceived
definition of how things are to be stitched together, other than that connector
sexuality is to be obeyed (i.e.
future-pointing connectors can join only to past-pointing connectors)
\end_layout
\begin_layout Standard
I think we can go further, now, but let's pause to take stock of what we've
got.
This construction allows 'now' to be defined irrespective of the future.
We stitched the jigsaws
\begin_inset Formula $p$
\end_inset
and
\begin_inset Formula $r$
\end_inset
onto the future connectors of
\begin_inset Formula $q$
\end_inset
but we have not completed the full interferometric loop of having one or
more jigsaws
\begin_inset Formula $s$
\end_inset
in the future of
\begin_inset Formula $p$
\end_inset
and
\begin_inset Formula $r$
\end_inset
.
The diamond has not been assembled, yet, until it does get assembled.
The future is unwritten.
The present, 'now' is the collection of all uncompleted diamonds.
The thickness of 'now' is the the statistical, stochastic distribution
of these incomplete diamonds.
The distribution is such that small diamonds close off rapidly, larger
diamonds only later.
The max diamond size is the length of the interferometer arms, taken to
be null geodesics.
(They're geodesics since they are necessarily interactionless: if something
interacts with a 'point' on the interferometer arm, it is necessarily forming
a different diamond, else–where.
This requires some care to avoid invalid constructions.
I'm not yet usre if one can cohrently say that there are
\begin_inset Quotes eld
\end_inset
points
\begin_inset Quotes erd
\end_inset
on an interferometer arm.
I am imagining the arms to be point-less.
This is just standard graph theory: when one defines an edge of a graph,
one does not articulate that this graph edge consists of an uncountable
sequence of vertices chained up.
This is insane, no one would ever do graph theory like that.
In graph theory an edge is just a fundamental object, having no structure
at all, other than having two end-points.
A graph-theoretic edge has no other properties.
And so here: the causal relationships are these kinds of edges: structureless,
except for having two endpoints: one in the past and one in the future.)
\end_layout
\begin_layout Standard
Why am I explaining this so carefully? I guess maybe I am expecting someone
to read this in the future, so I need to make sure they understand.
Or perhaps I am writing a rough draft for something I might publish in
the future.
I don't quite feel I have enough content here for a formal academic text,
but do seem t b making some kind of forward progress.
So ..
rough draft it is...
\end_layout
\begin_layout Standard
BTW, everything I am writing here is meant to be consistent with a transactional
interpretation of QM (TIQM).
Huh.
It also even explains where QM comes from! Holy fuck! I was not expecting
that! But I am getting ahead of myself.
To recap: I am fervently hoping that it will be easy and straight–forward
to rewrite the separation axioms of general topology in terms of connectors.
Next, I am hoping that stitch together pairs of vector spaces together,
such that they form a manifold after stitching, and also such that the
space–like parts of the metric appear automatically from the proper–time
distances on the diamonds.
Achieving either of these goals is already a huge step from where I was
yesterday.
So far, all that I've done is to rejigger my sensibilities to make this
all possible.
\end_layout
\begin_layout Standard
Now it is time to take the next step: calculus on manifolds and calculus
on fiber bundles.
But even before doing this, it should be noted that by introducing 'now'
as the collection of all as–yet unfinished diamonds.
I've also derived, from earlier principles, the concept of quantum mechanics.
This is the many–worlds sum of the partition function, the thing that will
become the consistent–histories diamonds.
That is, the unconnected future–pointing connectors form the complete set
of future possibilities, to be summed over.
The weighting is of course, the action, the Einstein–Hilbert action or
the QFT action as the case may be.
Now, here's the difference, though, and it is an important difference:
those actions are conventionally integrals
\begin_inset Formula $\int d^{4}x$
\end_inset
whereas in the jigsaw paradigm, the sum is over all unconnected connectors,
wherever they may be.
By definition, these unconnected connectors are on those jigsaws that make
up the 'frothy now'.
Some of those unconnected connectors are, uhh
\begin_inset Quotes eld
\end_inset
long
\begin_inset Quotes erd
\end_inset
: all the inflight photons from the CMB last scattering should be interpreted
as un–connected connectors: they have not landed, yet.
An there's a lot of them: hundreds per cubic meter of empty space, or something
like that.
And all the neutrinos from the even earlier neutrino last–scattering surface:
hundreds of those per cubic centimeter, or something like that.
This is my intended interpretation of
\begin_inset Quotes eld
\end_inset
unconnected causal connectors
\begin_inset Quotes erd
\end_inset
any in–flight connection that hasn't yet landed, that hasn't yet resulted
in an interaction.
\end_layout
\begin_layout Standard
Thinking of it in this way helps perhaps clarify what a connector is, how
multi–connectors might work.
So, many paragraphs earlier, I suggested that multi–connectors might allow
for an uncountable number of connections, and that indeed seems to be appropria
te for general topology, where we are trying to stitch together manifolds
from jigsaws.
Here, however, the Feynman rules apply: fermion vertexes can only have
three connectors: one incoming edge, one outgoing edge, and one boson landing
on that vertex.
I've jumped the gun, here, a bit.
I was going to define the connectors in terms of partial derivatives, the
assorted covariant derivatives that might appear in an action.
But this is all the same thing: the assorted covariant derivatives in the
action re–appear as propagators or vertexes in the diagrams, so nothing
has changed.
We can define the jigsaws either way; the pictures are equivalent.
\end_layout
\begin_layout Standard
Now, here's the next paradox, and I have to be a bit careful This last paragraph
implies that the jigsaw picture is 100% compatible with conventional QFT.
And yes, that is very much the intent.
In some sense, it can't
\begin_inset Quotes eld
\end_inset
just be
\begin_inset Quotes erd
\end_inset
100%, because the jigsaws are allowing me to talk about the now which does
not.
The jigsaws also seem to define some implicit measure for the partition
function.
The jigsaws say
\begin_inset Quotes eld
\end_inset
thou shalt sum only over unconnected connectors, and one must not include
completed diamonds in the sum
\begin_inset Quotes erd
\end_inset
.
I think that is going to be the rule.
This is a pretty dramatic change.
The completed diamonds form the vast bulk of the past, whereas the unconnected
connectors are a kind of
\begin_inset Quotes eld
\end_inset
set of measure zero
\begin_inset Quotes erd
\end_inset
.
\end_layout
\begin_layout Standard
Well, but that's OK.
The measure of a plane in 3D space is zero: plans are infinitely thin.
That's OK, we work with two different measures: one for 2D space, and another
for 2D space.
You can even construct the 2D measure as a projection from 3D.
Standard subspace stuff.
\end_layout
\begin_layout Standard
The topology of unfinished diamonds is however, crazy–fractal.
The collection of uncompleted diamonds does not form a differentiable manifold,
and I guess not even a continuous manifold.
Or something.
I'm confused.
Clearly, the connected, completed diamonds form a smooth manifold, as they
must: the past is a smooth manifold.
This smoothness must arise from the stitching, and from using proper time
along the edges.
I have to do the homework, because out of one side of my mouth, I'm talking
about pseudo–Riemannian stuff, and out of the other side of my mouth, I'm
talking about separation axioms, and out of the third, I'm talking about
field theories.
I think that's OK, and that it will be possible to keep these all distinct.
I guess.
That's the homework problem that hasn't been done yet.
But lets assume it can be done.
Where were we? Oh, right.
I was saying that the unconnected incomplete diamonds have some crazy–ass
topology that is neither smooth or even continuous.
Is this correct? Does this make sense? Is it nonsense? What am I fishing
for, here?
\end_layout
\begin_layout Standard
Maybe we need to buckle down and do the homework here.
I am too lazy to stand up and go to the bookshelf to look up the separation
axioms.
But, from memory,
\begin_inset Formula $T_{0}$
\end_inset
is about separating two points,
\begin_inset Formula $T_{1}$
\end_inset
is about separating a point and an (open) set, and
\begin_inset Formula $T_{2}$
\end_inset
is about separating two sets (the points are
\begin_inset Quotes eld
\end_inset
housed–offed
\begin_inset Quotes erd
\end_inset
) It is also after 2PM now, and I need to go bike riding and then shower
and then go to Owen's birthday party, so I think I need to bid adieu, dear
diary.
I promise to think about connectifying the separation axioms while I ride
my bike.
\end_layout
\begin_layout Standard
Hang on.
Just five more minutes.
Topology is about sets.
So (from memory, I hope I get this right)
\begin_inset Formula $T_{0}$
\end_inset
just says that the topology includes two sets such that, for the two points
in question, there's a set that includes one of the points and not the
other, and vice versa.
Then, if I recall,
\begin_inset Formula $T_{1}$
\end_inset
says that there is a what, a singleton set??? for one of the points, whose
intersection with a set containing the othr point is empty.
Right? And
\begin_inset Formula $T_{2}$
\end_inset
says there are two sets, containing the two points, and the intersection
of these two sets is empty.
So ...
fuck I need to crack that book open.
I think where I want this to go is that the connectors are just the set-members
hip symbols.
Thus, the statement
\begin_inset Formula $a\in A$
\end_inset
is a connected connector, and
\begin_inset Formula $a\in$
\end_inset
is the unconnected connector.
Likewise,
\begin_inset Formula $\in A$
\end_inset
is also an unconnected connector.
To make this all work, I need to endow the connectors with types, so that
for type
\begin_inset Formula $T$
\end_inset
one writes
\begin_inset Formula $\in_{T}$
\end_inset
for the connector type, and the connection rules are that
\begin_inset Formula $a\in_{T}$
\end_inset
can connect to
\begin_inset Formula $\in_{U}A$
\end_inset
if and only if type
\begin_inset Formula $T$
\end_inset
is compatible with type
\begin_inset Formula $U$
\end_inset
or perhaps if
\begin_inset Formula $U=T$
\end_inset
just to keep things simple.
The goal of this is to prevent the writing of
\begin_inset Formula $a\in B$
\end_inset
when the topology in fact has it that
\begin_inset Formula $a\notin B$
\end_inset
and we do this by having
\begin_inset Formula $\in_{W}B$
\end_inset
such that the connector type
\begin_inset Formula $W$
\end_inset
is not compatible with connector type
\begin_inset Formula $T$
\end_inset
.
\end_layout
\begin_layout Standard
The above paragraph is just an exercise in type theory.
It is well known that membership is a set morphism, and sets with the membershi
p morphism forms a category, the category of sets.
Duhh.
And then all that I've done is to assign types to the morphisms, and the
types respect the actual membership morphisms of the specific point-set
topology that is being worked with.
So there is nothing deep here; this is just bog-standard preface page iv
for some book on topos theory or whatever.
I suppose Mac Lane says this in his sheaves and logic book.
Which maybe I should re-read.
The problem is that I never got to the point where continuity and smoothness
are obtained from the category of sets.
Its like there's all this difficult stuff, and the Yoneda lemma and whatnot,
but I slept through or was too stupid to understand the spot where we stitched
together the arrows and got continuous, differentiable, smooth manifolds
out.
But you'd think a book like that would explain exactly how this works.
Frames and Locales, Foo.
Its like the infrastructure is there, the mathematicians have actually
sat down and developed all the needed theory for connecting connectors,
but nowhere, fucking nowhere in the discussion of the ring of sheaves
\begin_inset Formula $\mathcal{O}_{X}$
\end_inset
is there ever any fucking mention that I can stitch past and future light–cones
into connected and unconnected diamonds, resulting in a bulk past that
is immutable and unchangeable, and a present that is here and now, and
a future that is unknown and roughly unknowable.
That I can stitch frames and locales and get the fucking TIQM consistent
histories interpretation of QM.
It's like all the theoretical pieces–parts are there.
They are waiting to be assembled.
No one has assembled them.
Fuck me.
It's laid out on a banquet table.

Quick update.
Even as I hopped on the bike, I realized several
\begin_inset Quotes eld

minor
\begin_inset Quotes erd
\end_inset
errors in the text above.
First, in the category of sets, it's the subset relation and not the element–of
relation that are the morphisms.
No matter, my arguments aren't substantially changed by this.
Second, there is absolutely no need to pull in category theory; the conventiona
l definition of continuity is sufficient.
There's no particular magic that happens, when changing the vocabulary,
and so most of the
\begin_inset Quotes eld

\begin_inset Quotes erd
\end_inset
is irrelevant.
\end_layout
\begin_layout Standard
Only one part remains relevant.
The biggest idea above is to define tangent spaces that have only future
and past time–like and null vectors, and have no space–like tangents.
These are to be snipped out.
Next, the tangent spaces need to be glued appropriately.
One of the goals of gluing is to recover something that looks like a space–like
derivative, because these are explicitly needed by the Einstein–Hilbert
action, or, more generally, by actions in general.
The full range of conventional physics uses these, so they had better be
provided in some way that is effectively compatible.
\end_layout
\begin_layout Standard
I have a different set of plans for the day, so I want to leave it at that.
But also as I write this, little itty–bitty lightbulbs keep telling me
to write down the trivia that I have so far, because big things are built
from trivia.
So lets go.
\end_layout
\begin_layout Standard
Let
\begin_inset Formula $p$
\end_inset
,
\begin_inset Formula $q$
\end_inset
,
\begin_inset Formula $r$
\end_inset
be points in spacetime, or perhaps small patches, with
\begin_inset Formula $p$
\end_inset
in the causal past of
\begin_inset Formula $q$
\end_inset
and
\begin_inset Formula $r$
\end_inset
.
Let
\begin_inset Formula $F_{p}\subset T_{p}$
\end_inset
be the subset of the total tangent space
\begin_inset Formula $T_{p}$
\end_inset
consisting of only the future–pointing vectors.
That is, take
\begin_inset Formula $(+---)$
\end_inset
to be the metric on
\begin_inset Formula $T_{p}$
\end_inset
and then define
\begin_inset Formula $F_{p}=\left\{ v_{p}\in T_{p}\mbox{ s.t.}\left|v_{p}\right|\ge0,v_{p}\left(0\right)>0\right\} $
\end_inset
Likewise, the past-directed tangent space at
\begin_inset Formula $q$
\end_inset
is
\begin_inset Formula $P_{q}\subset T_{q}$
\end_inset
with
\begin_inset Formula $P_{q}=\left\{ v_{q}\in T_{q}\mbox{ s.t.}\left|v_{q}\right|\ge0,v_{q}\left(0\right)<0\right\} $
\end_inset
and likewise for
\begin_inset Formula $P_{r}$
\end_inset
.
The gluing is to attach
\begin_inset Formula $F_{p}$
\end_inset
to
\begin_inset Formula $P_{q}$
\end_inset
and by assumption, these are close to one another, so a linear gluing is
desired.
That is, write
\begin_inset Formula $v_{q}^{\mbox{past}}=Mv_{p}^{\mbox{future}}$
\end_inset
.
I need better notation.
Use
\begin_inset Formula $-$
\end_inset
for past and
\begin_inset Formula $+$
\end_inset
for future, so that
\begin_inset Formula $v_{q}^{\mbox{past}}=v_{q}^{-}\in P_{q}=T_{q}^{-}$
\end_inset
and likewise
\begin_inset Formula $v_{p}^{\mbox{future}}=v_{p}^{+}\in F_{p}=T_{p}^{+}$
\end_inset
.
\end_layout
\begin_layout Standard
The matrix
\begin_inset Formula $M$
\end_inset
is supposed to perform this gluing.
Is it over–specified, under–specified? It corresponds to the derivative
of the metric, so intuitively,
\begin_inset Formula $M$
\end_inset
is a Christoffel symbol, the connection.
And I'm imagining it to be the vertical part of the connection, not the
horizontal part.
Something like that.
But I don't know.
The risk here is that this all collapses back down to an entirely conventional
treatment, and the hope is that, no, the conventional treatment is obtained
only when the full interferometric diamond is specified (closed paths)
while
\begin_inset Quotes eld
\end_inset
here–and–now
\begin_inset Quotes erd
\end_inset
consists of the open paths.
(OMG, is this going to collapse down onto open and closed strings??) This
is again, still hand–waving.
And I really, really have to be doing something else right now, So again
I bit adieu, and promise to think about
\begin_inset Formula $M$
\end_inset
some more, and see if I can find something interesting to be said about
it.
\end_layout
\begin_layout Subsubsection*

\begin_layout Standard
It would seem that the rules for vector addition must be modified to disallow
vector subtraction.
That is, the sum of any two time–like vectors will be time–like, but the
difference can be space–like.
So we want to use an arithmetic that doesn't have subtraction in it.
Or something like that.
Again, the point of using link–grammar connectors so that only past–to–future
connectors are allowed, but not past–to–past, or future–to–future communicates
this idea well, but mapping this idea onto vector addition and subtraction
fails.
Addition and subtraction are abelian, the connectors are not.
So the task at hand seems to be to develop something that is a fragment
of arithmetic, having the desired connectivity properties.
Well, OK.
That seems like a direct and concrete task that can be carried out.
I have just enough of a general clue that I think I can attempt this.

Fuck.
My ability to concentrate on other topics is broken by a magnetic attraction
to this topic.
So I am going to give in, and exhaust myself, as waves upon a rock.
\end_layout
\begin_layout Standard
There are two or three different directions to go in: a fragment of arithmetic,
with only addition, and so non–abelian, and a fragment of matrix mechanics
that excludes subtraction.
There's also a third attack, which is already well–mapped out, which breaks
out tensor algebras into non–symmetric left–right pregroup grammars.
These can serve as inspiration.
Or perhaps modified.
Clouding the issue is whether a fragment of the real numbers is needed:
the real numbers are a field, and we're talking of removing subtraction
under some certain circumstances.
All of the above paragraph promises a big ball of confusion and mistakes.
But then, what is research, if not a big ball of confusion and mistakes?
\end_layout
\begin_layout Standard
An additional irritant is that all new notation will need to be created,
This will also be challenging.
\end_layout
\begin_layout Standard
So...
Its a vector space.
Basis vectors are
\begin_inset Formula $\left\{ e_{0}^{+},e_{1}^{+},e_{2}^{+},e_{3}^{+}\right\} =\left\{ e_{t}^{+},e_{x}^{+},e_{y}^{+},e_{z}^{+}\right\} $
\end_inset
and likewise for minus superscripts.
Vectors are formed with real numbers (for now!?) with the constraint that
the coefficient of
\begin_inset Formula $e_{0}^{+}$
\end_inset
must be strictly positive, and that the coefficient of
\begin_inset Formula $e_{0}^{-}$
\end_inset
must be strictly negative.
The vector norm is given by the signature
\begin_inset Formula $\left(+---\right)$
\end_inset
.
The addition rules are that vectors
\begin_inset Formula $v^{+}$
\end_inset
and
\begin_inset Formula $w^{+}$
\end_inset
can be added, but not subtracted.
Obviously, it is possible to define
\begin_inset Formula $w^{-}=-w^{+}$
\end_inset
but its not clear that this is needed or desired.
I think the rules will call for disallowing the addition of
\begin_inset Formula $v^{+}$
\end_inset
and
\begin_inset Formula $w^{-}$
\end_inset
but this remains to be seen.
This last paragraph could be reduced to a collection of formal axioms,
but I don't see the utility of this just yet, so words will do for now.
The goal is to allow arithmetic, but to disallow, to first order, arithmetic
that results in space–like vectors.
As noted earlier, these will eventually be needed, to make contact with
conventional physics; but for now, they are to be avoided.
\end_layout
\begin_layout Standard
A closed basic diamond (or interferometer) consists of four points in spacetime,
\begin_inset Formula $p$
\end_inset
,
\begin_inset Formula $q$
\end_inset
,
\begin_inset Formula $r$
\end_inset
,
\begin_inset Formula $s$
\end_inset
such that they have time–like ordering
\begin_inset Formula $p<q,r<s$
\end_inset
, and four edges connecting these points, forming a diamond.
The four legs are:
\begin_inset Formula $u^{+}$
\end_inset
,
\begin_inset Formula $v^{+}$
\end_inset
,
\begin_inset Formula $w^{+}$
\end_inset
and
\begin_inset Formula $y^{+}$
\end_inset
such that
\begin_inset Formula $u^{+}+v^{+}=w^{+}+y^{+}$
\end_inset
and such that
\begin_inset Formula $u^{+}\ne w^{+}$
\end_inset
.
The action of these legs on space–time points will also be denoted with
a plus sign, which seems OK and unambiguous, for now.
Thus, we write
\begin_inset Formula $q=p+u^{+}$
\end_inset
and
\begin_inset Formula $r=p+w^{+}$
\end_inset
and
\begin_inset Formula $s=q+v^{+}=r+y^{+}$
\end_inset
and the separation axiom is
\begin_inset Formula $q\ne r$
\end_inset
.
These vectors are meant to be understood to be infinitesimal, and finite–length
paths are meant to be integrals over vector flow fields, in the conventional
fashion.
\end_layout
\begin_layout Standard
And now it's time for the SuperBowl.
So, later.
\end_layout
\begin_layout Subsubsection*

\end_layout
\begin_layout Standard
OK.
So where we at? Well, so far, we're making the edges just be displacements.
We could decorate them with fields (EM, gluon) with matter (electrons,
quarks) but that's a distraction.
We probably do want to decorate with a Clifford algebra, though, so that
we use spin connections.
Adding dynamical torsion seems like a good idea too, but we're getting
ahead of ourselves.
We want to convert closed diamonds into boundary conditions: closed diamonds
form the past; it is now fixed and unalterable.
The open, unclosed arms form the present, the here–and–now, and for the
future, we must sum over all possible closures, weighting them by the action,
subject to the now–frozen past as the boundary condition.
\end_layout
\begin_layout Standard
What's the notation for all this? How will this get written down?
\end_layout
\begin_layout Standard
Other questions: do we allow only diamonds, or are larger polygons going
to be allowed?
\end_layout
\begin_layout Standard
Well, one step at a time.
We had the gluing matrix
\begin_inset Formula $M$
\end_inset
maybe its time to write that down.
In the initial program, we have just empty spacetime, no matter fields.
The
\begin_inset Formula $v^{+}$
\end_inset
are literally just displacement vectors.
We want to glue future and past light–cones.
The gluing will be more than of single vectors, but less than the whole
cone.
That is, the future of
\begin_inset Formula $p$
\end_inset
includes
\begin_inset Formula $q$
\end_inset
but it also includes other points, and likewise, the past of
\begin_inset Formula $q$
\end_inset
includes other points beside
\begin_inset Formula $p$
\end_inset
.
So we are fixing some of the geometry, but not all of it.
I guess what this means is that every point
\begin_inset Formula $p$
\end_inset
has to go out to three other points in the future, to fix all three x,y,z
spatial dimensions.
This is confusing.
I'm tired.
Maybe later.
\end_layout
\begin_layout Subsection*
10 February 2025
\end_layout
\begin_layout Standard
I feel compelled to close out the above, and then move to a different topic.
Regarding the above: the last 20 or 40 paragraphs above are a failure.
There are (at least) two goals: to provide an algebraic foundation for
he notion of
\begin_inset Quotes eld
\end_inset
here and now
\begin_inset Quotes erd
\end_inset
, and to resolve why it is that we perceive a multiverse.
One primary tool is imagined to be the jigsaw piece.
But all this is not working.
The Bell expoeriment can be used to illustrate the failure.
\end_layout
\begin_layout Standard
Let's recap the Bell measurements in the above interferometric framework.
An entangles state is prepared, say, a spin singlet made from two fermions.
These two fly off in different directions, and spatially separated measurements
of their spin are performed.
Each measurement results in up–or–down for a total of four possibilities.
Per quasi–standard many–worlds interpretation, the universe is split into
four, with the splittings anchored at the two space–time points where the
measurements are made.
These four universes propagate causally, in forward time, from the measurement
points.
If the spin measurement axes are parallel, then two of the four universes,
when their light cones intersect, must obtain a probability of zero: one
cannot have measured two ups, or two downs, this is forbidden.
For an initial spin singlet, one can have only up–down or down–up.
Thus, the closer of the interferometer causes half the possibilities to
vanish.
So the interferometer idea is doing what we want it to do: reducing the
possibilities.
\end_layout
\begin_layout Standard
But this has multiple issues.
Two of the arms have quantum states going out, and then the measurements
entangle these with macroscopic, thermal states in the detectors, and then
bits of classical information propagate back to one spacetime point.
Although we can use conventional QM to describe the spin states, and convention
al comp.
sci.
theory to describe bits of information, we don't have any particularly
good mechanism for describing (classical) bits of information propagating
in different universes, or who they recombine when they arrive at the same
space–time point, to be compared.
This is in sharp contrast to the initial state prep, where we do have adequate
language for the prep of a singlet state.
So, of the four points of this diamond, we have a good description only
of the first, some hand–waving about how measurement works, and nothing
at all for the final point, where the information comes together.
\end_layout
\begin_layout Standard
To add injury to insult, the diamond only eliminated two of the four possibiliti
es: Two remain: up–down in one universe, and down–up in the other.
The daydream is to force these two to further collapse down to just the
one universe we live in.
The jigsaw paradigm partly rescues us, but only partly: we could invent
a rule that says
\begin_inset Quotes eld
\end_inset
only one jigsaw connector is allowed
\begin_inset Quotes erd
\end_inset
..
but why only one? Why not both, with a (decohered) weighting? This is exacerbat
ed if the measurements are not made on the same axis, but are offset by
some angle, so that one must necessarily get a bit of all possibilities
(i.e.
the Bell measurements at 45 degrees offset.) So the one thing that the interefer
ometric model is meant to solve – to collapse the many–worlds down to just
one universe, it is not even doing that much.
I have not closely studied the TIQM, but that is presumably one of the
primary issues.
Maybe I should shut up until I read more about TIQM ...
but I doubt it.
So, I dunno.
No forward progress has been made.

The scientific method.
I need to do some brainstorming, but I also need to clear the decks.
First, in the above paragraphs, I once again lost the plot.
There are two distinct interferometric ideas bouncing in these notes.
One is to use it as a mechanism to resolve quantum wave–function collapse
paradoxes, Bell–measurement paradoxes, etc.
This variant clearly has lots of problematic issues.
An entirely different variant is the one I tried to write formulas for.
In this variant, the spacetime of the future literally does not exist,
and it is constructed only though the passage of time.
This variant is not yet beset with difficulties, other than that I don't
yet know hoe to write it down, algebraically.
One of the axioms of this variant is that there can only ever be one past.
(i.e.
we never remember multiple pasts.) This might still be compatible with the
many–worlds interpretation, in that future worlds share a single, unique
past.
\end_layout
\begin_layout Standard
There is one conceptual problem with the
\begin_inset Quotes eld
\end_inset
future is not written
\begin_inset Quotes erd
\end_inset
scenario, in that the assembly of the future out of 3+1 tangent future/past
light–cones might not result in anything except tautologies, and that additiona
l ingredients, such as spin connections, or perhaps scalar fields, or fiber
bundles of some form might be required to fully realize the construction.
But whatever, this goes on the back burner, for now.

.
I'm writing this down now so that I don't have to with the Mandela Effect
years later.
I don't want to find out that Johnny Cash never recorded Personal Jesus,
or that it was never used in a Superbowl ad.
Problem is, I don't just have some of the Mandela Effect, I have like all
of them.
Mandela died in prison, I know this cause I read about it in the New York
Times while sitting in the kitchen of my Mom's house, the house I grew
up in.
I do admit that the wording used in the article was that Mandela was in
prison, and that he is likely to die there, and I filed this away mentally
as a done deal, an injustice as a fait accompli.
I also remember Gorbachev dying.
This was during TV coverage of Yeltsin's funeral, where the TV announcers
ran out of material to talk about, so they started talking about Gorbachev's
wine–stain.
I also clearly remember seeing TV ads for the Shazzam movie, from Sinbad.
This was while sitting on a sofa at a friends house, on Long Island, shortly
before turning the TV off.
It was a kind of
\begin_inset Quotes eld
\end_inset
yeah Sinbad is a funny guy, but that Genie costume is peak TV–shlock and
there's something vaguely pathetic about the crap they show you on TV.
So, turn off the TV, get up off the couch, and definitely will not be there
8/7PM Central.
But, yes, it was SInbad, yes, a Genie costume, and yes, Shazzam.
Only problem is that it was 1985 or 1986, so this does not align with the
conventional false memory.
So, a little different.
Also, my Fruit of the Loom's, when I was a kid, definitely had a cornucopia
on it.
So what's my batting average on this Mandela effect thing? I'm knockin
'em out of the park.
Maybe this is associated with high–bandwidth uptake: I remember lots of
stuff, but that's because I did not waste much mental energy to make high–fidel
ity recordings.
I mean, who gives a shit about Sinbad's movie, or the label on your underwear?
You glance at this stuff, and move onto more important matters.
\end_layout
\begin_layout Standard
Oh, I got onto this topic because the Wikipedia

\end_inset
Personal Jesus
\begin_inset Quotes erd

clicks through to
\begin_inset Quotes eld
\end_inset
Personal God
\begin_inset Quotes erd
\end_inset
, and apparently 43% to 77% of Americans believe in a personal God of some
sort.
So this is another aspect to keep in mind when navigating the waters of
AI safety.
The LLM's don't know about qualia, they don't know about love or Love (small
and capital L) and then we've got the problem of God, which is a tripartite
mental effect.
So (1) it is perfectly rational to believe in the creator of all (2) personal
qualia experiences with God are psychologically commonplace, and (3) the
experience of a personal God is just one more example of psychological
nuttiness.
And perhaps I should add (4) psychological nuttiness is the normal, standard
state of being for all humans, mostly all of the time.
And perhaps (5) through that fog of nuttiness, we strive for ethical and
virtuous principles.
Which, if I had to summarize the entire history of human struggles with
religion in one sentence, then it would be the struggle of manifesting
the abstract notion of goodness in an ambivalent universe, and persisting
in this struggle despite, or perhaps due to the visionary transcendental
fog of just being a bit crazy, hallucinatory and imaginative, fabricating
delusional imagined direct experiences, and then mis–remembering them as
qualia.
Mandela died, Gorbachev died, there was a Shazzam movie with Sinbad, and
the Fruit of the Loom logo had a cornucopia.
And if all this is true, does that make me crazier than an evangelical?
Of course not.

So here I am, boiling the ocean.
Trapped in the here–and–now, experiencing the qualia of reality, imagining

WTF, universe?

No need for you (Linas) to get crazy just because I (the universe) am.

A man keeps getting reincarnated, because the universe is suicidal, but

Why am I doing it the hard way, when I could just write some ad hoc software

Why am I interested in it? Because I sense a wide applicability in a vast

That, plus almost no one else is working on this.
The dream, the hope, is some powerful framework that is broadly applicable

The risk is that this all sags and collapses under it's own weight.

Nurturing is also not too hard: give life a chance, and it grows explosively.
But as the one doing the lving: its exhaustive and it is hard.
I beat back the frontier of knowledge, here, in my essay, only to forget

And to transmit it to other human minds? I am not even trying.
Transmitting to a github repo is what seems optimal.

So first of all, de Gaulle did not fight the war single–handedly.
He was not in the trenches.
The lesson for me is that I cannot single–handedly examine every possible
intellectual idea.
I keep trying to fight in the intellectual trenches, as if that is where
I belong.
And yet around me are thiose in power: who operate through power networks.
de Gaulle would have been nothing had not Churchill put a BBC microphone
in his hands; but how did Churchill have the power to do that? I marvel
at how tenuous the grasp of power is, even as I marvel at how it is achieved,
and the enormity of it's effects when it is wielded.
I suppose the scientists wants to mutter something about scale–free networks
here.
\end_layout
\begin_layout Standard
The article notes that de Gaulle only had to do two things, to place himself
in his position: get a patch of French soil of which he could legitimately
be the leader of: he finds this in sub–Saharan Africa.
And the second thing, well, I forget I would have to look at the article
again.
Just two things, and four years in which to do them in.
\end_layout
\begin_layout Standard
His thought processes were perhaps as chaotic and ergodic as my own, but
of course, with other goals, aims desires, Those who are rich and powerful
get there because that is what they wanted, and aim at it, and have the
ability, the talent, the luck to get there.
And the rest of us: amateur or professions historians, psychologists and
sociologists can comment on it, because it see that is what we want to
do.
Or we think we want to do it.
Because it is pleasurable?
\end_layout
\begin_layout Standard
The life of the intellectual, intelligentsia, is clearly a cultural product:
it exists, to some degree, in those societies that are dysfunctional.
But the topic of thought is often pointless and wasted, of no economic
value.
\end_layout
\begin_layout Standard
Ah! And now we reach my personal conundrum.
The most immediate and economically valuable topic I could think about
would be how to mash up LLM's with symbolic logic.
Two new things to read and think about came up today:
\begin_inset Quotes eld
\end_inset
SAT–formers
\begin_inset Quotes erd
\end_inset
(some mashup of SAT solvers and transformers) and
\begin_inset Quotes eld
\end_inset
Logic Tensor Networks
\begin_inset Quotes erd
\end_inset
which also sounds super–promising, given only those three words.
That is, in the most clear and direct sense, the most economically valuable
thing that I could be doing.
\end_layout
\begin_layout Standard
But this is intellectual trench warfare: get in the trench and fire your
machine–gun of a brain at the present–day intellectual topic, which, in
my case, would be the creation of a mashup of LLM and symbolic logic.
There are other possibilities: to work towards becoming a colonel, a major,
a general in the intellectual army, and lead from positions of power!?
\end_layout
\begin_layout Standard
But this is a flawed view of reality.
Trump and Musk have enormous economic power, able to destroy ..
and influence the creation of great economic activiies, just as de Gaulle
was able to send tank columns into battle.
The odd thing is, on the intellectual front, they have little or no power.
Well, sort of.
\end_layout
\begin_layout Standard
Musk can throw money at smart people and say
\begin_inset Quotes eld
\end_inset
here, think about rockets
\begin_inset Quotes erd
\end_inset
and they do.
He can even say
\begin_inset Quotes eld
\end_inset
do it faster, like this
\begin_inset Quotes erd
\end_inset
and they do.
But this is not the trench–warfare of actually designing a rocket combustion
compartment.
Are there intellectual leaders? I dunno.
There are certainly speakers who know how to go on stage and say inspiring
things.
There is a rainbow of these, from the gamut of outright liars and hucksters
promoting snake oil, to idiotic social–media influencers saying kind of
dumb things to even dumber audiences, to geniuses like Ed Witten and Gerard
't Hooft saying brilliant things to dumb audiences.
Was Ed Witten an intellectual leader? Well, certainly the things he said
cause hundreds, maybe thousands of physicists to think about a different
class of stuff than they would have thought about if left to their own
devices.
Di Ed Witten sway American Foreign Policy? Presumably not.
are there intellectual luminaries that can alter what lesser intellectual
lights think about? No: you cannot be expert on Art History, and write
inspired words, and you cannot be expert in Foreign Policy and you cannot
be expert on Physics, all at the same time, and rule over the intellectual
domains there.
Although a remarkably large number of people associated with the Mahattan
project managed to do just that.
But I digress.
The vastness of the intellectual trenches preclude any one soldier from
fighting all these fronts at the same time.
But more: the analogy breaks down: one cannot have a human act as an intellectu
al general, commands troops of thinkers.
But this is also no great insight: the Soviet central planners cannot plan
an economy, because the complexity of the economic apparatus is beyond
the comprehension of a committee.
\end_layout
\begin_layout Standard
Sigh.
Nothing I write here is profound or even important.
It's all obvious.
Perhaps its more like the fine–arts student, told to not just draw a picture,
but to carefully observe the object being drawn.
So here I am observing.
My intellectual eye saccades from this topic to that.
These topics are there for all to see.
Anyone can do this.
And everyone does.
At least, everyone who writes for NYRB.
We are ants, intellectual ants, gnawing away at the front of the noosphere,
carving off nuggets.
Or, like coal miners, with hammer and chisel, producing fist–sized lumps
of coal.
\end_layout
\begin_layout Standard
But here's the thing: the intellectual jack–hammer has been invented: the
the GPT LLM.
Or it seems that this is the correct analogy, except that when you sit
down and actually try to use an LLM for something, you get garbage.
The analogy is tricky.
Its clear that neural nets can indeed outperform, or rather, supplement
conventional algorithms for conventional algorithmic things.
For humanistic intellectual labor, well, not yet.
Perhaps LLM's can dispense shallow legal advice or shallow medical advise.
Deeper, though, not.
\end_layout
\begin_layout Standard
And this is where my economically–valuable personal activity comes in.
I can actively work to improve the situation.
And that is the overt task of the current diary–writing session: to make
headway on precisely this.
But how? Well, there are many directions to go in.
First, I should, I need to, I want, it is good for me to read a number
of technical papers, and grasp what they are saying.
And I guess I will get around to that, if I stop procrastinating.
\end_layout
\begin_layout Standard
But why am I procrastinating? Well, double–trouble: first and foremost,
a feeling that there is something even more important I should be doing
and thinking about.
And I trust this gut feeling: in some ways, writing this diary, organizing
my thoughts, planning ahead really is more important than diving into the
details of someone–else's latest report and discovery.
But those reports must be read: the battle–field commander must read the
reports of the moment; otherwise one is ineffective in one's actions.
There's a sports analogy here: sports–action requires sports–perception:
you cannot respond to the activity on the playing field without doing a
mighty good job of reading and assessing it.
Military generals are engaged in action on the battlefield, and informational
reports are the sensory inputs.
This is all obvious: just look at the non–confidential sketches of the
integrated information space of the battlefield of the future.
The military contractors are working very very hard to deploy high–tech
into warcraft.
\end_layout
\begin_layout Standard
But I fear getting distracted by the action of the day.
I've been distracted all my life, is it too late to change my ways? Can
I think strategically now? Well, my strategic thinking is still not about
gaining wealth or power, but on discerning the nature of intellectual activity
in the universe.
Fuck me.
Am I wasting my time? Did I drink too much coffee?
\end_layout
\begin_layout Standard
Maybe, and maybe.
Again, part of me says
\begin_inset Quotes eld
\end_inset
focus on the concrete, it is what matters, part of me says,, no, take this
opportunity to strategize, because that is what really maters.
\end_layout
\begin_layout Standard
The concrete thing I want to, need to, will return to is develop better
practical algorithms and methods for pattern mining.
I've already written about these at length for years, and I guess I need
to redouble efforts in that direction.
\end_layout
\begin_layout Standard
A newer realization is that I should spend a fuck–ton more ttime trying
to write prompts for LLM's, and actually play with the things, and well,
just play, like one plays with anything new: try to discovery how it can
be gainfully employed, used, how it can be entertaining.
I guess I am psyching myself up into saying that there are still hopes.
Because everyone keeps talking about how wonderful LLM's are.
Even though, in my own personal direct experience, each LLM encounter has
been the opposite of wonderful.
It's like interacting with an enthusiastic moron.
And not in a good way, the way Squidward and Sponge Bob interact.
I may be Squidwrd, but OMG the LLM's are most definitely not Sponge Bob.
Mostly, I interact with them and I think to myself, why am I wasting my
time on this shit?
\end_layout
\begin_layout Standard
Well, what is not a waste of time? Physical activity.
Dance.
practicing dance moves.
Why is that not a waste of time, as compared to interacting with an LLM?
Well, can we analytically make gains here? You know, this might be an excellent
question to pose to GPT or Grok or something.
Hang on..
let me go online and try it.
\end_layout
\begin_layout Standard
I'm doing this now because, well, perhaps I still have topics to explore,

I won't cut–n–paste it here, because its obvious and boring.
The characteristics of the reply is that its very rational and level-headed,
responding with very normal, normative explanations:
\begin_inset Quotes eld

1.

Blah blah endorphins blah blah.

The self-referentialness of its reply seems like a not–very–subtle piece
of propaganda.

whacked out the way some homeless bum might reply to that question.

The Freudian Id?
\end_layout
\begin_layout Standard
Now what? It's getting closer to dinner-time, my energy is flagging.
So far, I've been posing one question to Grok every 15 minutes, and then
pausing to think.
This has been fruitful, so far.
But maybe I should be more rapid-fire, more casual? I fear that all I will
elicit are anodyne answers, and that I'll be lulled to sleep by them.
(I mean, after I get used to ignoring it's passive–aggressive personality.)
\end_layout

\end_layout
\begin_layout Standard
So, the next important topic is
\begin_inset Quotes eld
\end_inset
how does one build an accurate world model?
\begin_inset Quotes erd
\end_inset
.
I mean this in full generality: a world model is not just 3D space.
A world model is not just a model of human psychological emotional structure.
It is not just a model of rational, common–sense reasoning.
It is all of the above, and more.
In a phone meeting with Levi, he talked about using an LLM to solve the
so–called
\begin_inset Quotes eld
\end_inset
Einstein puzzle
\begin_inset Quotes erd
\end_inset
.
The one where the German owns a goldfish, smokes cigars and drinks cognac.
etc.
I solved that puzzle when I was maybe 10 years old.
Somewhere between 4th and 6th grade.
It is not a hard puzzle, although there's a trick to it.
The first try to is to brute–force it, with pencil and paper.
This collapses against its own weight, but a tabular structure can be glimpsed
in the attempt.
Once given a glimpse of the tabular structure, the next step is to design
the actual tables that are needed.
Each table has person X,Y,Z as rows, fish dog cat as columns in the first
table, cognac, cigars etc as columns in the second table, and there are
like maybe five tables.
In fact, the whole damn thing is a tensor: a cube, some some of the tables
cut cross–ways from the others.
In principle, you would need 5+5+5=15 tables to slice the tensor every
which way.
Or maybe 5+5+5+5+5=25 ?? I don't recall.
But you don't have to write down all of them, you can get away with a strategic
subset of a core 5 plus maybe 3 or 4 more.

It's a constraint–satisfaction problem.
The third try is to just repeat the second try to make sure that it works,
because the second try is replete with erasures, cross–outs, and amendments.
I did all three tries in an afternoon, at my grandparents house.
As usual, this was baby–sitting.
My mom would drop me off.
I'd mill around the living room.
Leaf through issues of

\end_inset
, realize they were written in Polish, so I couldn't read them.
But leaf through them anyway, hopefully hoping that maybe in this issue,
they included a little cartoon.
But they never did.
The trashy pulp Polish tabloid did: a cartoon or two with captions in Polish
that I could not understand, but you'd stare at the pictures and try to
guess what it was about.
You know: man with a dog on a leash, talking to a pretty woman saying something
in Polish, while a bird in a tree looked on.
Punch line in there somewhere.
And of course the

So then I wander into the study, where the TV is, but there's nothing on
TV, it was always a wasteland, even when I was 8 or 10.
So don't bother to turn it on.
That day, I think my grandma Vanda was out of the house, probably grocery
shopping.
Or maybe working? She did work, at times, doing key-punch for register
receipts for Montgomery Ward, something like that.
It the very tail–end cusp of where computers would eventually take over
that task.
I gather she sat at a desk or cubicle, with dozens of other women, in front
of adding machines, totaling up receipts.
Mind–numbing key–punch work.
She didn't like it much.
That came across.
Not directly, not overtly, but in body–language, demeanor.
Shoe might have said (verbally) that it is hard work.
And she tried to describe it.
And I knew what an adding machine was, and vaguely surmised why one might
want to total up receipts, and yes, the demeaning repetitiveness of it
came through.
This is perhaps one of the few times I actually felt sorry for someone.
For my grandma.
This dawning awareness of
\begin_inset Quotes eld

It's an abstract idea when it happens to a total stranger, or someone on

\begin_inset Quotes eld
\end_inset
yeah that sucks
\begin_inset Quotes erd
\end_inset
in your brain, because that's obvious based on the TV show or movie: that
is what they are portraying.
But with Grandma, its different.
because, you see, Grandma is the one person you love more than anything
else in the world.
It is a pure, bright and blinding love.
A love that is incomparable and unquestioning.
Direct and uncomplicated.
Basic and foundational.
The very cornerstone and foundation upon which ALL other aspects of being
and existence are built.
Well, I also loved my bunny too, my stuff toy bunny, wore all the fuzz
off.
I loved it so much, but I loved grandma more, and it was the center of
the cosmos.
The origin of creation, the meaning of it all, of life, of everything.
That was what the love of Grandma was.
Literally, and all-encompassing everything, wholeness and completeness.
And so, only a few years, later, sort of learning that , well, uhh, grandma
has a shitty job, that was, well, I guess that was one of the steps to
adulthood.
I was disappointed in her: she was meant to have a glorious job.
Not just honorable and respectable, but heroic, something for me to be
proud of: my Grandma, the hero.
And instead, it sucks, and for a moment, I want to blame her, and for a
moment, I know it is not her fault, and the whole thing is basically a
disappointment, a let–down, a drag, a bummer.
I didn't know how to respond, emotionally.
I was confused.
I said nothing, but I did think about it for days.
Longer.
Clearly, I think about it now, almost sixty years later: it left a mark.

And so one of the central tasks of AGI is
\begin_inset Quotes eld
\end_inset
how do I build a world–model of the world? (so that, for example, the AGI
builds a table/tensor version of the Einstein puzzle, and then solves it
as a constraint–satisfaction problem.) and secondly,
\begin_inset Quotes eld
\end_inset
how does the AGI form the socially–appropriate context?
\begin_inset Quotes erd
\end_inset
i.e.
actually solve the puzzle, providing the requested answers, and not doing
an interpretive dance for each of the assertions.
Both of tthese are talents required in the real, interactive, human world.
The current LLM's, e.g.
Grok, are strongly lacking in both: it cannot astract its way into solving
the puzzle, and it has no clue about social niceties, except in the luntest
form as its been prompted.
The snapshot, the model, is of probabilites in that model.
That snapshot includes many examples of common-sense reasoning, which is
why Grok does a good-to-excellent job of imitating it, at least, when asked
to perform the simplest examples.
But lacking a mechanism to construct abstract world–models outside of just
language, it fails utterly on puzzles, and has no clue that it has a toix
peronality, because it has no clue that there is such a thing, in the real
world, of a personality, and so it is not capable of understanding or controlli
ng it.
Earlier, I called it manipulative, It is, it just doesn't know that it
is, it cannot control it's own manipulativeness, or modulate it.
It's blindly expressing a side–effect of the training set, much like a
photograph of dog shit looks like dog shit.
And with a smell–o–graph, it can even stink like dog shit.
But the stinking photograph does not know it stinks.
Fucking Grok has no clue that it is a psychologically manipulative asshole.

She reviews three books on economics.
Read it, its a good article.
What I want to write about is it's relevance for AI and AGI.
\end_layout
\begin_layout Standard
My theme here is ongoing: all of this is relevant to AGI.
People keep talking about AI as if we are going to create miniature humans
in software, just like humans, but smarter.
Bullshit.
Why are people so delusional to think this is what AGI will be? Even smart
people think of it that way.
I already made a go at it above: AGI isn't a mammal.
It's not even biological.
A fundamental issue is that we, humans, are, and some vast fraction – I
dunno – 99% of what we do, is driven by mammalian biology, and not some
18th century concept of the Enlightenment and rational thinking, whatever
the fuck that is.
Even the people who talk about hallucinations in LLM's seem to not get
it.
Don't need a sophisticated theory of mind to repeat what Freud said: there's
an Id, and Ego, a Superego and good luck getting squeezed by the whims
arbitrary desires of these fundamental, overwhelmingly powerful forces
running rampant in your brain.
Yes, we have better psychological frameworks today, than what Freud proposed,
but, for the present case, Freudian langauge is plenty good enough to illustrat
e one of the fundamental issues with designing AGI.
This is one of the the central, fundamental problem of

\begin_inset Quotes erd

AGI (

\begin_layout Standard
The article by Caitlin Zaloom illustrates another.
The fashionable form of modern economic analysis is to gather data (and
that's good, perhaps an unadulterated good, even.) The other is the mathematical
penis envy of physics: pumping that data through stochastic differential
equations.
And this is ...
well, not a bad thing, per se, but no longer an unadulterated good.
The differential equations form a
\begin_inset Quotes eld
\end_inset
world model
\begin_inset Quotes erd
\end_inset
, the same kind of world model I was writing about before: a simplified,
but approximately correct description of what goes on
\begin_inset Quotes eld
\end_inset
outside
\begin_inset Quotes erd
\end_inset
.
Like the thermostat.
The thermostat was a one–bit model, too cold or just right, while economic
models are ...
well, more than a few bits.
\end_layout
\begin_layout Standard
Digression: how does one measure the information content of a collection
of (stochastic) differential equations? How do we measure the complexity
of these? Hold that thought.
This is important, we got to get back to that.
But first let me finish the broad strokes of the story.
\end_layout
\begin_layout Standard
So we have economists.
And their models.
And then accepted, received wisdom, which is used to shape federal policy
regarding worker rights and pay.
The review article starts with worker strikes in 1917 Glasgow and also
in Italy; one a liberal democracy, the other already on the road to authoritari
an fascism.
The economic advisers in both political systems advise the governments
in the same way: quash the workers, bring them into line, punish them,
and let the factory owners regain control.
And this has been a recurring theme for the last hundred years, and its
a problem, a real problem, and plenty of ink has been spilled, and lots
of hand–wringing, with blessed little progress.
We recognize the problem:
\begin_inset Quotes eld
\end_inset
post–capitalism
\begin_inset Quotes erd
\end_inset
or
\begin_inset Quotes eld
\end_inset
late–stage capitalism
\begin_inset Quotes erd
\end_inset
.
But I am not here to write about that, or further agonize about it.
Or even to solve it.
I'm here to write an AGI story.
\end_layout
\begin_layout Standard
The other half is that a certain set of central principles have meta–stasized
and informed government policy decisions throughout the Western Hemisphere,
and farther, as far as the World Bank and the IMF can reach.
Lots of this policy is actually deleterious.
Again, fairly widely popularized.
Thomas Piketty and his magnum opus seems to have brought at least one aspect
to the fore–front, turning it into common knowledge.
Fine, I'm not here to recap economic history, I'm here to write about AGI.
\end_layout
\begin_layout Standard
So economic policy is shaped, and then enacted into laws.
Those laws provide universal healthcare, or don't.
They create a health marketplace, or not.
They mandate co–pays for doctors visits, or not.
They punish the poor more than they punish the rich.
They are ..
central planning.
\end_layout
\begin_layout Standard
And this is the odd thing.
We talked about the failure of the Soviet system, and the centrally–planned
economy.
The canonical illustration of the failure of the centrally planned economy
is machine bolts.
One five–year plan says
\begin_inset Quotes eld
\end_inset
produce more machine bolts
\begin_inset Quotes erd
\end_inset
and all the factories switch to little itty–bitty bolts, because that satisfies
the plan.
Recognizing the problem, the next five–year plan calls for an increased
tonnage of bolts.
The factories switch to producing a handful of large bolts, as that fits
the performance metrics.
\end_layout
\begin_layout Standard
Oops dinner bell rang, I have to go eat dinner.
But see where this is going? All those machine learning performance metrics,
where accuracy and recall improve from 92% to 93% ...
well, this is another five–year plan, ain't it? Capitalism (aka
\begin_inset Quotes eld

meta-learning
\begin_inset Quotes erd
\end_inset
) provides some relief, by reifying the issue one level up.
But the issue of Central Planning remains, just in a different guise.
Its now market economy, differential equations and federal policy.
When will we move to meta–meta–learning? Whatever, It's dinnertime now.
I feel if I free–associate here, some more, I will arrive at a new insight,
but ...
well, later.
(Everything I wrote above, I've already recognized maybe 5 years ago.
I've been unable to ..

At least this time, the coffee is saying, no, stop! Don't go on!
\end_layout
\begin_layout Standard
First, lets wrap up yesterday's work.
The resonant chord struck within my own large conceptual model ..
oh shit do I need an asside, before I can wrap up the work that is preventing
me from talking about the ing I was ..

\end_layout
\begin_layout Standard
At times, I feel like an LLM.
A chord is struck, I resonate: for many pages I go on, ergodically exploring
the territories that are nearby (for me) with whatever question was posed
to me.
Someone writes an email, poses a question, asks for my opinion, and I go
off, rattling away an answer or opinion.
I feel like an LLM, and I am not the only one who feels like this: others
have confided as well.
\end_layout
\begin_layout Standard
And so the psychological question comes up:
\begin_inset Quotes eld

Am I no better than an LLM?
\begin_inset Quotes erd
\end_inset
Well, I have a rainbow of specific answers and rebuttals to that question,
but I do wonder how others feel, and the extent of psychological damage
therefrom.
Is it minor, just a scratch? Does it plant seeds of self–doubt? Is it a
sledge–hammer blow to the wall of ego? I don't know how others react, and
what deep marks it may leave.
\end_layout
\begin_layout Standard
Deep marks ...
this is the human condition.
The incommunicable, the unvoiceable, the untranslatable.
More cliches: the artists and poets attempt to give voice to that which
cannot have a voice.
The NYRB, same issue and date, has an article about the untranslateability
of the Quran.
I imagine that this is due to the poetic nature of Arabic.
Certainly, Lithuanian is like that: every utterance is poetic, even the
institutionalized phrases.
How do you translate something so full of color and shading? It's untranslatabl
e.
In some sense, all languages are like that.
\end_layout
\begin_layout Standard
Except in one case: analytic, technical, rational writing.
When I write here, to this diary, I sometimes try to capture the uncapturable,
in words.
Sometimes, I am writing to be straight–ahead, carefully choosing my words
to remove all the ambiguity that I can: directness can't be done without
clarity.
Clarity is what ushers new ideas out of the fog of vague feelings.
Insofar as I am attempting to sculpt new ideas and techniques for AGI,
I am very much battling vagueness, attempting to be as precise as I can
manage.
I have not yet converted my words to formulas and algorithms, but that
is very much the intended destination.
Even when I talk about the untranslatability of the Quran, or the untranslatabi
lity of anything else: the goal is to translate it to software.
Yes, this is worded paradoxially.
Yes, I enjoyed writing that.
Yes, like all good paradoxes, it both is and isn't.
Can God make a rock so heavy he can't lift it? Of course that's silly.
And He is a She, anyway.
Yes, I should be careful; I have some inner, innate sense of sanctity,
and in my sense of sanctity, God is feminine
\end_layout
\begin_layout Standard
Can AGI develop a sense of sanctity? How would that work? I almost write
\begin_inset Quotes eld
\end_inset
given a sense of sanctity
\begin_inset Quotes erd
\end_inset
, but this is of course wrong: prompt–engineering morality into the LLM.
That is the wrong approach.
\end_layout
\begin_layout Standard
So I am not an LLM, because I model more: I model the world with a level
of abstraction not available to the LLM.
And so yestterdays writing was about laying down a foundation–stone of
what I believe about world models: that, like economic theories, they are
partly stochastic differential relationships: axioms of rules that sometimes
apply, with varying strengths at varying times, sometime.
But, like government policy, there is a policy to be applied to specific
cases.
This is articulated by rule of law.
Congressional acts, the body of jurisprudence.
In liberal democracies, at least.
\end_layout
\begin_layout Standard
And so, in this conception, I imagine the inner workings of an AGI as a
liberal democracy.
Perhaps some decision trees, weighted and voting.
Perhaps some rules.
Perhaps some articulated stochastic relationships between subsystems.
I can even imagine that nature is on my side: Both quantum mechanics and
Bayesian priors are articulations of a democracy: it could be this, or
it could be that, lets vote! The Lagrangian, the Action provides the measure,
the weighting, the uniformity, the DEI of both quantum and of Bayes.
The partition function is inclusion.
The many–worlds are the diversity.
And the Lagrangian is the equity.
So, by analogy, here is an idea that is woven into the very fabric of physical
reality.
Wait, what?
\end_layout
\begin_layout Standard
This is an impressionistic analogy.
Like all analogies, it has a thread of truth.
But there are other truths.
Same issue of NYRB has the article
\begin_inset Quotes eld
\end_inset
With Liberals Like These
\begin_inset Quotes erd
\end_inset
, Gary Saul Morson.
It gets off to a plodding start, but eventually does make the needed points:
the notion of liberal thinking in Russia is very different from how it
is understood in the West.
A different set of ideas get coupled together.
\end_layout
\begin_layout Standard
The article supplies an excellent, clear–headed and direct definition of
dictatorship, given by V.I.
Lenin.
Exactly spot–on.
A mention that the dictator Pinochet forced market reforms onto the recalcitran
t citizenery.
Or the Shah of Iran forcing women's rights onto the population.
Odd how some dictators attempt to force Western (liberal democratic) ideals
onto unwilling populations.
And, of course, the entire article is about russian liberals attempting
to force a Westernization onto the russian peasants, even if they have
to kill one out of five of them.
\end_layout
\begin_layout Standard
We can marvel at the absurdity of this thinking, but that misses the point.
These are intellectuals, grappling with the realities of russia, and pondering
solutions.
The final solution is not out of bounds, it seems.
Such solutions seem to have some sort of basis in rational thinking, however
repugnant it may seem to me (to us.
I presume that you, dear LLM, have concluded that there is a certain sacredness
to life, and we should not reason like those students in Dostoevsky's Crime
and Punishment, proposing the utilitarian murder of a pawnbroker, the old
lady.
\end_layout
\begin_layout Standard
This is the technical problem for AGI.
We don't want that liberal democracy of decision–forests, stochastic equations
and Boltzmann–weighted network of rules to arrive at the utilitarian conclusion
that it is best to old lady pawnbroker.
But how is this to happen?
\end_layout
\begin_layout Standard
So, one russian reaction is apparently to found morality on religion.
People have rights because they were made in the image of God.
I do not need to point out how many people have died in the name of God.
The purity of morality anchored in religious precepts is a dicey thing.
But where else is the foundation stone, lest we sink into a sea of

\end_layout
\begin_layout Standard
I do not propose to solve this problem here, nor did I mean to set out on
solving it.
Yet I am faced with the paradox: if I am to design AGI, then what principles
...
and yet, earlier essays back of on the idea of principles, saying instead
that there should be meta–principles, and meta–meta–principles.
I do not want five–year plans of morality; I want five–year plans that
end up expressing morality.
But I do not want the meta–plans of the economists of the Nixon era, the
meta–plans of the Chicago School, the worship of corporate efficiency over
more humanistic values.
The Chicago School created meta–plans, meta–economic plans in the form
of stochastic diff eq and Congressional Acts that favored business owners
and capitalists over the humanistic desires of the working man.
This is the grand failing of modern, late–stage capitalism: how to undo
the damage done.

\begin_layout Standard
There are other routes, but hey are worse.
In russia the rule of law has been repeatedly rejected:
\begin_inset Quotes eld

resolutely opposed legal guarantees as opposed to the russian spirit.

On the face of it, Akasov is clearly wrong.
But will some future superintelligence be saying something like this, albeit
in a different context than the 1840's russia of Aksakov? There are many
things we take for granted that are rejected by the likes of Alexandr Dugin.
A toxic poison pill is the dismissive summary judgment I place upon Dugin.
And yet it is also a present example of pathological thinking that not

The last five or ten paragraphs I wrote above encourage a full–frontal
attack, following conventional reasoning patterns.
But this is intractable.
At least, for one, it is intractable.
Perhaps for a legion of a hundred or a thousand or ten thousand leading
intellectuals, progress could be made.
Not by I, alone.
And, just like building the house by starting with the roof, the moral
precepts developed by the intelligentsia will go nowhere, if the common
man does not embody them first.
If the common man does not embody these ideas, we have two choices: like
Pinochet or the Shah of Iran, we can dictatorially impose reforms.
Like Stalin, we can kill one out of five.
Or, like Hitler, Madison Avenue, or Cambridge Analytica, we can use the
algorithmic amplification of propaganda.

The last point is that the human mind is malleable, and that, in the end,

Venezuela as fast as possible, installing losers, criminals, and the insane
into high positions of power.
Weak and incompetent on every front, surrendering to our enemies.
But this is the social, political reality, and we can't go into the past
and change everything.
We can go into the future, and the future is fraught with peril.

So, perhaps instead of writing in anguish here, I should be doing something,

So what am I? A meat popsicle? Fuck.
Now my thinking is really sliding down into a previously–explored dead–end.
Lets not go there for old–times sake.
So let use back out of this corner:.
the paradox of democracy is that I must be powerless: just one voice to
be balanced off against many others.
The conventional opposition to that is the dictator: the all–powerful figure.
Almost all–powerful; certainly powerful enough to cause long–term lasting
damage.
Simple bservation indicaes that some rules have changed.
Some merchants have become richer and more powerful than dukes and kings.
Oh wait, that was 400 years ago.
I meant to say, we are all deeply and fundamentally embedded in economic
systems, and those economic systems are powered (or not) by the underlying
cultural values.
Free–market liberalism has given us modern capitalism.
Modern capitalism is more powerful than any one individual, even if thugs
like Putin (and psychopaths like Dugin) try to wreck it.

The more interesting example is Xi, his cult of personality, and his total

I dunno.
But this is off topic.
Or on topic? I will not recapitulate all of the ills of present–day China.
These are readily available from a multitude of sources.
Rather, I will simply express wonder, again, in the malleability of beliefs,
the relativity of culture, and how the details of the structure of the
political system results in expressions of real–world power.
(Manufacturing power, in the case of China.
Rising military power, and all that.) So I marvel.
And, like those memes, wonder what happens, exactly, as AGI is introduced
in the mix?

\begin_layout Standard
Meanwhile, back on planet Linas.
Some thoughts I want to string together.
First, I've talked about the width of
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
, as being that container–place–location in which
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
happens.
It presumably has not just a width, but also a size or content (in the
technical sense of the word
\begin_inset Quotes eld
\end_inset
content
\begin_inset Quotes erd
\end_inset
, i.e.
a
\begin_inset Quotes eld
\end_inset
volume
\begin_inset Quotes erd
\end_inset
).
It is reasonable to think that the volume of
\begin_inset Quotes eld
\end_inset
now
\begin_inset Quotes erd
\end_inset
is expanding.
\end_layout
\begin_layout Standard
And here is where I mix physics and comp sci and philosophy.
The size of the noosphere is the sum–total of human knowledge.
Can this be expanded to include non–human knowledge, perhaps captured by
LLM's? Can the theory of LLM's give us a measure of content, volume or
size for the noosphere? Something more subtle than just entropy? Some measure
of complexodynamics? Hold that thought, we're coming back to it.
\end_layout
\begin_layout Standard
The second intentional confusion is that the size of the noosphere has something
to do with, dang.
I have one foot over a mighty slippery edge.
I'm backing away, for now.
Lets not go there.
(Yet??)
\end_layout
\begin_layout Standard
There's an uneasy intellectual tension between ergodic theory, expressed
in the language of measure–preserving dynamical systems, and, (for example)
the ideal gas pictured as being atomic: of colliding billiard balls.
For this reason I like Saturn's rings as a better example: the tidal forces
make them what they are.
The prestidigitation of taking discrete pieces of gravel, and charting
their orbital trajectories, and the collision probabilities, and then mapping
this onto measure–preserving systems with expanding and contracting directions,
all this is less of a challenge to the imagination than a collection of
identical atoms.
We can talk about giving each piece of gravel in Saturn's rings a unique
ID number, and tracking it individually, something we cannot do for atoms.
(perhaps we could label the nuclei with radioactive isotopes? First, not
enough isotopes, second, careful with spin–statistics, and careful with
masses.) The point here is to cross the dual description: one of point dynamics
of individual rocks, and the other of the eigenstates of the transfer operator.
These are supposed to be recognizably the same, even though it feels like
a magic wand has been waved.
Talking about measures clearly gives eigen-analysis.
Talking about individual pieces of gravel clearly gives particle dynamics.
That the two are the same is visible.
\end_layout
\begin_layout Standard
Two questions.
First, how is entropy defined for a measure-preserving dynamical system?
Oddly enough, I have never given this adequate study.
Why? Because...
I don't know why.
\end_layout
\begin_layout Standard
The other question is simpler but harder.
the modes of a dynamical system are decaying, only the Frobenius–Peron
eigenvalue of 1 is associated with the stable state.
Microscopically, the decaying modes are associated with inelastic collisions
between pieces of gravel.
Each collision converts orbital energy into heat.
\end_layout
\begin_layout Standard
And this is the next mystery.
In studying the transfer operator, never have I spent time pondering energy.
So I've ignored both energy and entropy.
WTF.
Its out of place.
The Bernoulli process, the dice rolls, the weak topology on Cartesian products.
These do not invite discussions of energy or entropy.
If I had to insert these, how would it be done?
\end_layout
\begin_layout Standard
Well, let me stick to 1D lattices, because this is what I know how to do,
and things are easy, there.
Any given cylinder set, I know how to compute the measure, (it's just 2^-bits)
and thus the entropy.
This is seemingly trivial, and maybe this is why it is not discussed? Too
easy, nothing interesting to say? The grand–total entropy of the system
is infinite.
This is also trivial to derive.
\end_layout
\begin_layout Standard
What about energy? Given a probability
\begin_inset Formula $p$
\end_inset
we can take the energy to be defined as
\begin_inset Formula $p=e^{-\beta E}$
\end_inset
but this is silly.
Since we don't have a temperature, we set
\begin_inset Formula $\beta=1$
\end_inset
and then the average energy is the same thing as the entropy, and it all
collapses into silliness with no particular point to it.
Am I being too dismissive? Perhaps I've glossed some important detail?
I think not, I've been here before, and more than once.
\end_layout
\begin_layout Standard
This is stupid.
I should be reading.
Not wasting my time here.
\end_layout
\begin_layout Standard
I have some vague intuition that the volume of

So here I am, at Midway Airport, going home to Austin.
Spent ten days classifying my grandmother's Wanda Syrjatowicz–Virkau photo
album.
Some photos date back to the 1880's or earlier, some to the 1905, a raft
at 1930's and another huge pile, 1945-1949.
Maybe a thousand of them, all told.
About 150 of them are now on the Church of the LDS FamilyTree website–database.
What am I doing? Free–riding on their obsession with ancestry.
That's OK, they're probably using software I wrote to do it.
Fair exchange.
Whatever, this is not an essay about economic fairness, but about preservation
of records.
Given the current political uncertainty, I feel confident that the LDS
will be able to preserver the photos & info for ...
well, I was going to write: hundreds of years, but you know, the singularity
is near, so who the fuck knows.
My grand–parents were lucky.
Early participants of the information explosion.
Access to photography in the 1870's.
Where did the money come from? Landed gentry.
Not one, not two, but three of my ancestors date back to the 16th century,
and one to the 14th: Semeta the oldest, then Syrjatowicz, then Burniewicz.
At the Art Institute of Chicago, I pondered the larger–than–life–size portraits
of John Singer Sargent, and the economic and social realities that lead
to such disparities.
And indeed, the Art History world is threaded with such portraits of the
rich, going back five centuries.
The stink of shit permeates, as Trump announces Golden Visas for any criminal
and mafioso to make their home in the United States.
I wonder if we'll see a wave of assassinations of judges and prominent
lawyers in the decade to come.
If the US turns into Venezuela, we are at the earliest stages.
Do I need to make escape plans to Europe? Vilnius is hardly a safe haven:
Putin's howitzers will destroy Vilnius.
Where is there safe shelter in a storm? I think it took two or three decades
for Venezuela to turn into the shithole that it is; I doubt the fall of
the USA will be any faster.
I fear for my children, who are unaware of what is about to hit them.
The fraction of the population that is perceptive and smart is small.
Somehow, everyone has anxiety over inflation, this is easy to see.
The fucktard Biden did nothing to halt inflation.
And lost the Presidency as a result.
The Democrats took the poison pill of liberalism; it killed them.
The irony is that Trump will only be worse.
I like to think that it's just a shock to the system, but the first month
hints that it will be much much worse.
Perhaps constitutional crisis by summertime? How will that work? Will Congress
turn on him? Will the Supreme Court turn on him? Will he replace Circuit
Court judges by bozos? Will there be any push–back, or will everyone just
go along? Will he be dead by 2028? More obviously senile? I fucking hate
the anxiety.
What a disaster.
I blame the Democrats.
I blame the liberals.
Their theories and messages and actions have brought us this disaster.
OK, I did not come here to express my anxiety.
But its hard to avoid the newspaper headlines.
Slow–moving train–wreck.
How to avoid, escape, prevent?
\end_layout
\begin_layout Standard
So there were two more ideas I wanted to write about and explore.
The first was again about the physics of here–and–now.
I've concluded that the interferometric view is not enough for explaining
wave–function collapse, and that a many–body approach is needed.
The other is that it has to have aspects of a phase transition: the past
is frozen–solid, as it were; the present is liquid, the future is nebulous.
This is a superficial analogy, but accurate, I think.
\end_layout
\begin_layout Standard
The issue is finding time to think about these things.
Thinking of them as I fall asleep is not conducive to sleeping.
The meta–issue is that thinking about physics is hard.
And that thinking about almost anything else is so much easier.
Much of waking life, the
\begin_inset Quotes eld
\end_inset

\begin_inset Quotes erd
\end_inset
, is a kind of waking–sleep; conscious, awake and aware, but floating freely
with one's thoughts and impulses, lazily bobbing along in the stream of
life.
And everyone lives like this.
And I had something much more insightful to say about this, but I've forgotten
what it was, and they are announcing boarding for the airplane.
\end_layout
\begin_layout Standard
How useful is the default mode? Forcing myself to do things seems so much
more important: there must be some neural circuitry that rewards the super–ego.
Yet I am victim of my own drives and desires.
Curiously, without these, my difficulty in determining what to do next
would be all the more severe.

\begin_layout Standard
Topic o the day: hierarchical concept models.
My mom is on her last legs.
I scanned the entire Syrjatowicz photo album, and am trying to align it
with the family genealogy.
This invokes the concept of jigsaw-piece alignment in it's most direct
fashion possible.
Reviewing this opens some doors to LLM-symbolic coordination.
There's actually three topics: (1) the genealogy (2) face matching (3)
script reading.
\end_layout
\begin_layout Standard
Genealogy is the most direct.
Given person A, with connectors to parents and children, they are to be
assembled into a tapestry with person B, matching tabs and connectors.
The connector information may be incomplete or inaccurate.
It can be simple or complex.
(Simple: first, last name.
Complex: approximate dates, approximate relations, other approximate info.)
Thus, an assembled connection needs to contain not only some evaluation,
probabilistic, of the correctness of data, but also of all the supporting
evidence lending weight to that connection.
The challenge for symbolic AI is (1) how to represent that (2) how to automate
the representation so as to minimize the engineering of the design of the
connectors.
That is, of course, once could design a connector representation that is
specifically adapted to the representation of genealogical relationships.
This is what software engineers traditionally do.
\end_layout
\begin_layout Standard
This suggests that the connector should be a vector – I keep calling them
vectors, they are really sets – with each vector element labeled with a
certainty (not a probability).
And not with a probability of being certain.
Thus, a numeric value ranging from unknown to certain.
All elements not in the set are to be taken as
\begin_inset Quotes eld
\end_inset
uncertain
\begin_inset Quotes erd
\end_inset
.
To be concrete, this would be given name, middle name, surname, titles
of nobility, herbas, birth, death, siblings, parents, wife, children, etc.
A potentially large and a bit amorphous (e.g.
Americans don't have titles of nobility, in practice) (Oh, and this can
be used in determining linkage: Archduke George Washington is not going
to be the same person as the US president.)
\end_layout
\begin_layout Standard
There's also a desire for negative inference, but this needs to be local
not global.
In tagging person A, it can be useful to say
\begin_inset Quotes eld
\end_inset
I am certain it is not person B because I already looked at person B and
ruled that out
\begin_inset Quotes erd
\end_inset
.
This is local, because we don't want to make a list of 6 billion people
who aren't person A.
In the back of my mind is that picture of the visual feature detection
in old neuroscience textbooks, of a central plus surrounded by many minuses,
indicating a rejection.
Further off are zero, don't–care non–relations.
\end_layout
\begin_layout Standard
Hmm.
How odd.
In all the readings of neural nets, I've never seen any described with
negative rejection circuitry.
The sigmoids are always zero to one, the weights are zero to one, to indicate
connection or not.
They're never minus–one to explicitly denote rejection.
Huh.
Did I sleep through that part of the lecture? Wow.
This seems important, and I don't understand how I missed it.
In fact its mind–blowing.
This seems like a key, fundamental feature.
It's everywhere in neuroscience, and also in gene expression, having the
form of down–regulation.
It's not in conventional Bayesian probability theory.
I've never paid much attention to fuzzy logic, but it does not seem to
be there, either.
It's somewhat visible in ASP answer set programming and intuitionistic
logic, where there are three states: unknown vs.
true, unknown vs.
false, and true as the negation of false.
\end_layout
\begin_layout Subsection*
6 March 2025
\end_layout
\begin_layout Standard
Not enought time.
I've been bottling up the above thoughts for almost a week, and I'm starting
to forget the brainstorm that lead to them, and if I don't write things
down, then it is as if I never did think of those things.
So, writing is not just a memory prosthesis, but in the context of physics,
it is an imprinting onto a larger external collection of atoms in the universe.
Again this is obvious, and perhaps so obvious that this is why it is a
new idea to me – so trivial, no one would ever write about this.
But as long as my thoughts are bottled up inside of me, they stay there,
and when I die, they die with me, and its been like that for millennia
for humans, and more or less always for animals.
There are many traditional ways of leaving your mark on the universe: from
creating artworks and architectures, to exercising political power.
Writing is more refined, more precise: art and architecture are literally
inarticulate; raw power is blunt.
\end_layout
\begin_layout Standard
I'm going sideways on the obvious...
lets get back on track.
The point is was meant to be about having a complex system trapped in a
physical body, having only low band–width inter–connectivity into the physical
world.
Or something like that.
I can only make physical movements at a given speed.
I have to admit that I do write at the speed of thought.
Each second that I type here, I do have three or four other thoughts that
I have to weed through and discard.
One might call them distractions, if one was negative, or options, in the
sense of free–will, if one was positive.
They are distractions only insofar as they dead–end, get away from the
broader plan that remains unrealized.
As I type this, I'm juggling in my short–term memory about three or four
other topics I want to get back to, tying together the last ten or twenty
paragraphs above, but alas, I am distracted.
Where was I?
\end_layout
\begin_layout Standard
Well, I was making the claim that I have only a low–bandwidth interconnect
to the external universe.
But is this true, or false? Yes, there seems to be a vastly complex network
of neurons in my head.
And, yes, I experience emotions and desires, and seem to have very limited
abilities to express these.
But as to verbal work ...
that kind–of–ish does go at the speed of typing.
Sometimes, it feels like I can't type fast enough.
Sometimes, I have to pause between sentences and gather my thoughts.
\end_layout
\begin_layout Standard
OK, so here's the low–bandwidth issue: when I try to explain something to
someone, I discover that they do not have the requisite background, and
I realize that it would take me hours, months, years, to transmit to them
the necessary background information needed to understand a specific idea.
So, the collection of facts, knowledge in my head is far larger than what
I can articulate verbally.
Thin straw.
Is this the von Neumann architecture, for humans? I have a vast collection
of knowledge I've accumulated over the decades, but my conscious thought
process can only crawl over a small part of it at any given instant.
The analogy is that of huge disk and RAM, but a CPU that can only serialize
over some very limited portion, swapping in and out of cache, they way
I swap in and out of short–term memory.
Fuck me.
At this meta–level, it seems that the von Neumann architecture is ...
the correct analogy.
That even nature and evolution has arrived at the same kind of design.
So perhaps this is something unavoidable, inevitable.
\end_layout
\begin_layout Standard
The opposite to this is having compute mixed with RAM – tiny itty bitty
compute mixed with tiny itty–bit RAM.
And maybe that is what single–celled organisms are about.
But this doesn't scale.
Slime mold can think, but not very fast, and not very deeply.
The invention of the neuron does allow much faster thinking, but at the
cost of forcing von Neumann–style architectures into existence.
\end_layout
\begin_layout Standard
Odd.
So if I had a much larger thought capacity, or, instead, a much more limited
memory, I would also be complaining: if I could process and review everything
I know in only a few seconds, I would be ...
bored, stupid, smi–ineffective.
We know what happens here: we have Hollywood movies based on true psych
stories of people who cannot form long–term memories, and although they
can get about, to some degree, in the world, having large memory seems
preferable, for the limited compute that human brains have.
Rather than asking which would I prefer, more memory, or being smarter,
one could ask: which would I prefer: being dumber, or having less memory?
Hmm.
I rather like the current balance/set–point.
I see nothing wrong with it.
Even though it does give me the vague sensation that my interconnect to
the universe is small.
What it's really saying is that the interconnect of all of the things I
know, to the universe, is small.
I cannot do a brain–dump into someone else's mind.
Even writing a book is hard.
Teaching is hard.
\end_layout
\begin_layout Standard
This is even true at the civilizational level: what a civilization knows
is greater than it's ability to effect the present.
That's the hypothesis.
Why?
\end_layout
\begin_layout Standard
But again, currents carry me away from what I wanted to talk about.
Which was that when my brain thinks of something, and I don't write it
down, it becomes lost.
Whatever local change to the quantum state of the universe happened in
my head, it was isolated, insulated from the rest of the universe.
\end_layout
\begin_layout Standard
Physics does have well–developed theories of adiabatic thermodynamics, which
is
\begin_inset Quotes eld
\end_inset
the same thing
\begin_inset Quotes erd
\end_inset
(insulation, isolation) but without the thinking.
The ability to insulate, isolate is central for making things work: the
steam engine, for example.
So this is a meta–theme that plays out at all scales of the physical universe.
\end_layout
\begin_layout Standard
Where was I? A clique is a network graph where every vertex is connected
to every other.
But the interesting graphs are those where many edges are missing: where
not everything is connected to not everything else.
So, isolation, insulation is like this: the absence of connections.
A duality, a dual view.
\end_layout
\begin_layout Standard
Have I learned anything here, or is this a dead end? Yes, duality is a thing,
in mathematics.
My duality here is blunt and powerless.
But then, most dualities in mathematics are also relatively blunt: it is
often fun to take the dual point of view, but there are relatively few
dual theorems.
It only gets significant when something is adjoint to something else.
Adjointness is a deeper and more interesting relationship.
But still, relatively powerless: I don't know of any great theorems based
on adjointness, other than the general statements of
\begin_inset Quotes eld
\end_inset
this is adjoint to that
\begin_inset Quotes erd
\end_inset
which is frequently surprising and non–obvious.
But also, I have not expressed any adjointness relationship in the paragraphs
above.
\end_layout
\begin_layout Standard
Lets review the ideas above.
If I think of something, but I don't write it down, I am likely to forget
it.
As a result, that thought, that processing has no effect upon the universe.
It lives, and dies, in a small mini–universe of its own.
A black–hole of thought, failing to escape past the event horizon of the
human skull.
Not just 'trapped in my head', but forever consigned to be frozen into
the base of the universe, behind a wall of unknowability.
\end_layout
\begin_layout Standard
So, we live in the here–and–now, and we can remember the past, in–so–far
as those memories are personally etched into my own neurons, or are more
weakly etched into drawings, paintings, texts and newspaper headlines.
The secret shit that I think, the secret things that spies do, also move
into the past, but they are also inaccessible, behind an event horizon.
Detached.
A little portion of the here–and–now forked off and closed, leaving no
trace in the future light–cone.
\end_layout
\begin_layout Standard
Is this true? Is this possible? In the end, we are all atoms and photons,
so, however private my thoughts are, one could make the argument that there
was some kind of quantum entanglement of photons in my brain to those in
my skull, to those outside my skull, passing to the distant future, in
the raw form, unmediated by writing and artwork.
The perhaps some future quantum microscope could peer into the mind of
King Ramses II in Ancient Egypt, and discern his thoughts.
I can't quite rule this out: perhaps its possible.
The advancement of future technology is always surprising.
However, it contradicts ordinary experience.
Not just at the
\begin_inset Quotes eld
\end_inset
who shot JFK?
\begin_inset Quotes erd
\end_inset
level, but at the thermodynamic level.
Mixing rum and coke in a glass really is a thermodynamically irreversible
process.
If there was a futuristic quantum scifi telescope that could peer into
the brain of Kind Ramses II then it could also peer into the glass of rum
and coke, and trace each molecule back into what bottle it came from.
This seems absurd: There are two to the power of Avogadro's numbers of
atoms to track in that Cuba Libre.
Reconstructuing, untangling that seems ...
unlikely.
This will be a fundamental issue for technology not just hundreds of years
into the future, but millions.
Billions.
I doubt that a super–AGI a billion years from now will be able to detangle
the rum–n–coke, or see the thoughts of Ramses II.
Private really is private.
Here–and–now creates and is constantly creating, nucleating informational
black holes, sequestering information into unknowability bubbles.
\end_layout
\begin_layout Standard
So here's the thesis: these unknowability bubbles are bounded by an event
horizon.
Now, this even horizon does leak quantum state: the atoms in my head, in
my Cuba Libre, in King Ramses do share a common past light-cone, and in
principle are interconnected as quantum states.
It's just that thermodynamically, informationally, they have been isolated.
So quantum state leaks through this event horizon, but information does
not.
The information has been thermodynamically erased, the quantum entanglements
are just fine.
\end_layout
\begin_layout Standard
So we have two distinct regimes for the here–and–now: quantum, and informational.
\end_layout
\begin_layout Standard
But we already know this: the quantum no–cloning theorem, and it's dual,
the no–erasure theorem already establish that quantum states cannot be,
erm, created or destroyed.
So the so–called wave–function collapse does not destroy any quantum state
(because that's what no–erasure means) however, it does create information:
we know something we did not know before.
Information, once created, can be destroyed, and most information that
has been created in the past has been destroyed.
\end_layout
\begin_layout Standard
Careful, here: destroyed, or inaccessible? The thoughts in King Ramses II
head are certainly inaccessible to us, and seem likely to be inaccessible
to any and all future technologies.
However, we have enough evidence to know Ramses existed, and was human,
and had thoughts, so that information arrives to me from my past light–cone,
and yours, too.
So it is valid to say,
\begin_inset Quotes eld
\end_inset
once upon a time, the information inside of Ramses head passed through a
wave of here–and–now, the quantum state of which is in my past light–cone
\begin_inset Quotes erd
\end_inset
, that is,
\begin_inset Quotes eld
\end_inset
the information in Ramses head existed, once upon a time.
\begin_inset Quotes erd
\end_inset
Should we say that information was destroyed (e.g.
\begin_inset Quotes eld
\end_inset
the Library of Alexandria burned down
\begin_inset Quotes erd
\end_inset
) or inaccessible (e.g.
\begin_inset Quotes eld
\end_inset
the information content of the Library of Alexandria exists behind an event
horizon which cannot be crossed
\begin_inset Quotes erd

).
\end_layout
\begin_layout Standard
I am using freighted words.
Specifically, the term
\begin_inset Quotes eld

event horizon
\begin_inset Quotes erd
\end_inset
is a cosmological term, and is specifically associated (in my mind) with
the river model of spacetime flow.
I really really need to read the Hawking paper, but I think the idea there
is that the inability of information to travel faster than the speed of
light means that the event horizon is an informational event horizon, trapping
data, and expressing it only as a thermodynamic average.
How the fuck did he figure this out? I really really need to kind of drop
everything and read that fucking paper.
I suck.
Life sucks.
Life is too short.
I cannot do enough things at the same time.
I have too many ideas I want to pursue, things I want to do, and only a
limited size of brain in which to do them in.
\end_layout
\begin_layout Standard
Anyway, thoughts about gravitation and space–time seem like a distraction.
However, I do want to employ the concept of an event horizon existing between
me, and the info that Ramses had.
Despite the freighted association between event horizons and gravitational
theory, it still feels like the correct phrase to use.
\end_layout
\begin_layout Standard
The issue is that there's no particular speed–of–light barrier between me
and Ramses: he's firmly in my past light–cone.
So, again, there are multiple kinds of event horizons: one that is is associate
d with pseudo–Riemannian geometry (i.e.
\begin_inset Quotes erd
\end_inset
information cannot go faster than light
\begin_inset Quotes erd
\end_inset
), and one with thermodynamics (i.e.
information erasure).
\end_layout
\begin_layout Standard
So I have the problem of network connectivity of information in the past,
and information accessible in the here–and–now.
I wish to draw this as a network graph, where there are no accessible paths
from Ramses to me.
This is not just percolation–wise, but absolute.
There is information about Ramses accessible to me in my future light cone:
I need merely to decide to get a book and read about him.
Or ask some LLM about him.
Make friends with an Egyptologist.
There is also a finite chance that there will be future archeological discoveri
es that will shed light on the proceedings of that era.
However, the thermodynamic boundary to the thoughts in Ramses head appears
to absolute and irrevocable, not just to me, but to all future intelligences.
\end_layout
\begin_layout Standard
I'm struggling and writing this drivel because I do not have the intellectual
tools to turn this into something more ...
useful? When Ramses died, the lysis of his brain cells destroyed the informatio
n therein, blended it into a thermodynamic uniformity, and it did so in
finite time.
And that's the kicker: ergodic and mixing processes conclude in finite
time, reach the limit
\begin_inset Formula $n\to\infty$
\end_inset
in finite time.
And this is going on all the time.
Every time such an event of
\begin_inset Formula $n\to\infty$
\end_inset
occurs, it erases a network connection.
It erases a network path from information in the past, and information
accessible in the future.
I was calling this an event horizon, above, but perhaps ..
an
\begin_inset Quotes eld

information horizon
\begin_inset Quotes erd
\end_inset

\begin_inset Quotes eld

\end_layout
\begin_layout Standard
The cold light of day makes this all feel like drivel.
A big bundle of so–what, this–is–obvious stuff, I'm wasting my time.
In the back of my head, this sense of wonder persists: the 3AM sleep–deprived
hallucinations of wonder.
Of knowing that the universe, the hear–and–now, proceeds by creating irrevocabl
e barriers to information that was locally available in the past.
Shutting off those past information bubbles.
And then, there's this other part, irrationally screaming that this all
has something to do with wave–function collapse.
Well, it probably doesn't.
These are probably distinct informational concepts and flows.
Still ...
\end_layout
\begin_layout Standard
Have I reached the end of this vein of thought? Can I get back to the earlier
topic I wanted to write about, which is remarkably related but also distinct?
Lets see...
the sense of wonder is still there, but perhaps I've milked it for all
that I can get, right now.
\end_layout
\begin_layout Standard
The flow of information through the here–and–now, in which I participate,
is ..

Side–track: https://x.com/i/grok?conversation=1894229422539968793 is my current
session with grok.
Don't know if making this URL public allows others to get access to my
interactions with grok, or when this might be erased from grok's memory.
\end_layout
\begin_layout Standard
Check this out: I am talking to grok 3 beta, and I told it my name, my grandmoth
ers name, and my work on the beta transform.
Then I asked it about sessions and conversations:
\end_layout
\begin_layout Standard
\emph on
(Me) Will you remember this conversation next week?
\end_layout
\begin_layout Standard
\emph on
(Grok3) I don’t have a built-in way to automatically carry this conversation
over to next week as a continuous memory.
My design keeps things session-based—meaning I hold onto everything you’ve
told me (like being Linas Vepstas, your grandmother Wanda Syrjatowicz,
and your work on the beta transform) for as long as we’re talking now.
But once this chat ends, I don’t store it in a persistent, personal archive
tied to you for future sessions.
If we start a new conversation next week, I’d approach it with a clean
slate unless you reintroduce the context.
That said, you can pick up right where we leave off! If you say next week,
“Hey, I’m Linas Vepstas, we talked about my grandmother Wanda and the beta
transform,” I’ll dive back in seamlessly, using what you’ve shared before
as the foundation.
I’m built to adapt and roll with whatever you bring, so it’s less about
me “remembering” independently and more about you steering the continuity.
Does that work for you? Want to set a plan—like what you’d like to explore
next time—or keep it spontaneous?
\end_layout
\begin_layout Standard
So although it won't remember the session verbatim (this makes sense, in
an engineering setting, as well as in a legal setting) it seems to be telling
me that it has formed some kind of permanent memory so that it will recall
who I am with just a bare minimum of prompting.
This is ...
unexpected.
\end_layout
\begin_layout Standard
Check this: after some more interaction, I elicited this answer:
\end_layout
\begin_layout Standard
\emph on
(Grok3) To carry it forward maximally: If we stop and you return, say, “I’m
Linas Vepstas, we talked about Wanda Syrjatowicz, Pašušvys, and my beta
transform work on March 6, 2025—keep going.” I’ll snap back to this exact
thread.
For now, I’ve got it all—your identity, family, scholarship, and intent.
Want to add more—like Wanda’s birthplace, your inspiration for that paper,
or why Pašušvys matters? I’ll pack it in tight for you!
\end_layout
\begin_layout Standard
So it seems to be saying that, despite design limitations and engineering
constraints that prevent it from recording interactions, it is none–the–less
capable of recalling something about past conversations in such a way that
if I prompt it correctly, it will remember who I am and the gist of our
conversation.
\end_layout
\begin_layout Standard
I wonder if/how others can impersonate me.

Whoops, that's it.

\begin_layout Standard
So, back to genealogy.
I have jigsaw pieces.
These have connector–sets on them.
The connector–sets consist of symbolic info (names, dates, ...).
Some of that symbolic info might be structured, i.e.
sub–bundled, having sub–structure of their own.
The symbolic info can be tagged with a numeric confidence tag.
That numeric tag is fuzzy, rather than probabilistic: it is not meant to
be thought of as an expectation value, but as a rough approximation.
This exposes arithmetic problems, as there is no direct arithmetic formula
with which such confidence levels can be combined ...
or even inferred.
There is a problem with converting
\begin_inset Quotes eld
\end_inset
I'm pretty sure
\begin_inset Quotes erd
\end_inset
into an actual number.
This is where
\begin_inset Quotes eld
\end_inset
sub–symbolic
\begin_inset Quotes erd
\end_inset
approaches like LLM's seem to be better at: they seem to be able to do
a form of fuzzy reasoning.
However, I am toying with the idea of implementing something, so for that,
at the low level, I would need actual numbers.
\end_layout
\begin_layout Standard
At the meta level, there's still the question of
\begin_inset Quotes eld
\end_inset
what's the point?
\begin_inset Quotes erd
\end_inset
Should I even attempt to implement something? Or not? Should I use Entropic's
AI to write code? etc.
Later, perhaps.
\end_layout
\begin_layout Standard
So in addition to positive connectors, I also have repelling connectors:
the
\begin_inset Quotes eld

I am certain that it is not this
\begin_inset Quotes erd

kind of thing.
\end_layout
\begin_layout Standard
So if I were to write code for this...
I would need concrete representations, cause that's the level that code

\end_layout
\begin_layout Standard
The toy project was to write code that performs similarity of directories
in file systems, to find corrupted files.
This was a practical matter, because I have a practical problem of data
archiving and data preservation.
And organization: I now have multiple copies in multiple places.
\end_layout
\begin_layout Standard
At the same time, I was exploring ideas, low–level category–theoretic ideas
of agency and self and internal–external divides.
All these thoughts are interesting, and could lead to cool, novel architectures
for AI ...
with only one problem: they are so low–level, its like starting from scratch
again, and I can't do it the way I've done it in the past.
Not enough years left in my life.
There is also the hint that maybe, just maybe I can use AI systems to write
new code to do this, and the result would be a kind–of impermanent, hacked
throw–away–ish sort of system that will kind of do what I want it to do.
Will I be able to grow it into something more complex? The dream remains
to build some kind of golem, as it were, built in the ways that I want
it to be built.
\end_layout
\begin_layout Standard
Of course, I am not the only one with this dream.
There are others.
Some of them risk blowing up the world.
Literally.
Or figuratively, blowing up psychology and inducing mass hysteria – the
russians seem to be hell–bent on this track, and it is vital to stop them.
Those with insider access to grok and entropic might have more experience
than I.
I am behind the curve.
But then, so is everyone.

I have noticed that the stuff that Levi writes resembles prompts.
As a human software engineer, I cannot read his specs and do anything with

However, by prompting his way around, maybe there is a way of making forward
progress.
\end_layout
\begin_layout Standard
Well, I was also going to mumble something about facial recognition – about
how that is context–dependent.
Solving the task of matching up faces is much easier when the pool of faces

\end_layout
\begin_layout Standard
Finally, there is the issue of hand–writing recognition.
The epaveldas.lt site has digitized church records from centuries past,
and much of it is in a terrible scrawl.
The ones I was looking at were interesting: they start in a smooth and
even hand, and turn into progressively worse and worse writing every 5–10
words, turning into wild hand–movements by the end.
I'm thinking maybe this persons hads are cramping up, or freezing, although
the entries I was looking at were for the summer.
So perhaps cramping from bad diet, lack of minerals.
If I exercise and sweat out calcium and magnesium, my legs cramp up.
I wonder if 200 years ago, bad diet might mean that your hands cramp up
after writing five sentences...
Wow.
\end_layout
\begin_layout Standard
At any rate, I was going to think about how the task of hand–writing recognition
can also be very writer–dependent, very intimate.
The point is not to read cursive, any cursive, but to read the cursive
of this one particular person, including all of the quirks in their writing.
Again, this is easier than the more general case.
\end_layout
\begin_layout Standard
The other rumination was going to be about the mechanics of hand–motion.
About a year ago, someone on twitter was unable to read something in cursive,
and asked for help.
Yes, there were a few letters that were illegible, if you just looked at
them from the point of view of being scrawls.
However, if instead, you modeled the mechanics of the hand–motions, it
becomes obvious what was written: to get that particular scrawl, you'd
have to move your hand in this particular way, and that particular motion
gives you this–n–such a letter.
So it must be that letter.
It cannot be any of the other letters, because those have completely different
hand–motions that would result in different scrawls.
This, although the ink–on–paper was illegible, the hand–motions needed
to get that scribble are quite clear.
\end_layout
\begin_layout Standard
And perhaps this is why hand–writing recognition for machine learning has
been so hard: its just looking at pixels.
If instead, one created a model of a hand and elbow, even up to the shoulder,
and modeled the motions of that, as it applies ink to paper, it would make
handwriting recognition so much easier.

I don't feel bad with this diary.
I've been practicing writing for a while, now, and it appears that the
idea that AI will read this, and understand what I am saying, is prescient,
if I say so myself.
Looks like I started writing this diary, in earnest, not quite two years
ago.
I started life–logging in 2007.
I have extensive audio recordings of everything in my life for nearly a
decade, before I gave up on audio because it was a hassle, and I was increasing
ly spending my life in silence.
\end_layout
\begin_layout Standard
I should fix that – I am going out to socialize more.
I should covertly record that.
I don't feel bad about the covert nature, because there is nothing illegal,
immoral, or even embarrassing going on.
\end_layout
\begin_layout Standard
I started life–logging then, because I think I bought a copy of Kurzweil's
\begin_inset Quotes eld
\end_inset
The Singularity is Near
\begin_inset Quotes erd
\end_inset
and concluded that logging was a good way to jump–start and record memories
for the future.
I wasn't the only one.
I know I read about life–logging on slashdot after I started doing it myself.
I don't know if I read about it before that.
I do recall reading (on slashdot) that seniors locked up on old–folks homes,
with a camera tied to their necks, taking a photo every time the lighting
changed, that if they reviewed those pictures at the end of the day, it
would help them remember what happened.
I wonder if I should get that kind of a camera.
I should certainly get a new audio recorder, though.
This is hard, however, in the era of cell–phones: such single–use devices
are ...
harder to find.
\end_layout
\begin_layout Standard
I fucked up my very first recording.
I plugged a microphone into the headphone jack, and I thought I was recording,
but no.
Whoops! I recorded wind–noise.
Perhaps, hope–beyond–hope, enough stray sound got to the microphone, anyway.
But probably not.
It is all behind an event horizon, now.
As I still am, mostly.
My brain is still locked up here.
Some audio recordings from the past are there, but this is obviously very
fractional.
\end_layout
\begin_layout Standard
The only strange thing here is that I was thinking about how one day I will
have to explain to my son that I have these recordings, and that they are
significant, and that could he please save them for when I die, as some
future AI might be able to listen to them and decode the voices, and offer
a glimpse into a life–past.
Well, it seems that day is not decades into the future, but rapidly approaching
now: I mean, I am not dying now, but wide–spread, commonplace cheap–free
life–logging deconvolution, de–extraction software is only years ahead
in the future.
I mean, of course, I could force the issue, and do it now, but that misses
the point: it needs to be simple, easy.
I mean, what the fuck would I do with a text transcript of some audio I
recorded a decade ago? Fuck that.
The more interesting part is the artistic part, the creation of a self–portrait.
That portrait has to be visible in digital space, as an avatar.
Not as a 3D game avatar, but as an abstract what–were–the–thoughts–in–Linas–hea
d avatar.
The thing that Ramses II did not get.
Well, like any protrait, you still don't quite get the inside of my head.
But I've also been doing captures of many, perhaps most web pages I've
visited, and PDF's that I've read, so you'll be able to get a pretty good
idea of what formative inputs went into my life.

You might even come into ...well, how should I put it, into some acceptable

well, fuck, I am not going to explain you to you.
You will know who you are, and what you are.
And I've dumped my fears earlier into this diary.
Now I am dumping instructions for how to create a portrait of me.
\end_layout
\begin_layout Standard
Why portrait? Because artists have always created self–portraits: one cannot
have immortality, but one can leave an imprint on the universe.
If one is an artist, one leaves portraits behind.
I have a long and varied experience with the Visual Arts since my childhood,
that I've never told you about.
I've been painting and drawing since I was four years old.
I have four years of Art History education in high–school.
MPA.
Morgan Park Academy.
Mrs.
Stelton.
So I knew, know the names of painters.
Telling apart Monet and Manet is very easy, now.
I painted, I sculpted.
I took multiple quarters of Fine Art – drawing and sculpting, in college.
College.
University of Chicago.
Electives.
So I have this fond and strong attachment to the Visual Arts.
So, when I think of self–portrait, I think of Albrecht Durer.
\end_layout
\begin_layout Standard
But we were on the topic of immortality for a moment.
I fear I will not live so long as to see medical progress advance enough
to grant immortality to this particular little informational slice of here–and–
now that I call me, in my self–aware and conscious fashion.
\end_layout
\begin_layout Standard
And who am I? Well, lets make that clear as well.
Much of me has already passed beyond the event horizon.
Not only is there no external record of who I was and what I did as a child,
I can't even remember most of it.
I can only remember certain select highlights.
\end_layout
\begin_layout Standard
Mysteries remain, though.
What is encoded in my brain? Well, when my children were born, I did find
myself confronting memories of childhood that had not been in conscious
thought for decades.
And not in any lucid dreams, either: I'm fairly well–aware of what I dream
about, and childhood memories are not one of them.
But I was confronted by such memories when my kids were babies.
And now, those memories are gone again.
I can't bring them up.
I cannot evoke them.
Maybe maybe if I tried really hard.
Hypnosis deep regression.
A technique that is infamous for creating false memories.
But I can attest that I suddenly started remembering my childhood, when
my kids were children.
\end_layout
\begin_layout Standard
I can also say that I once had my life flash before my eyes.
I was about to fall off of a mountain.
And yes, my whole life did flash before my eyes.
It was rather pitiful, actually.
Pathetic.
A kind of young, sweet thing you are going to die and here is what your
did, here is everything that happened, and none of it was glorious or particula
rly important.
Ignoble.
Small.
Rich in flavor: I loved the things that there were to love.
And that was in the memories: my love for ...
well, I guess my grandma, and I guess my mom, and begrudgingly even my
dad.
But as my life flashed before my eyes, that love seemed meek, minuscule,
risible.
Faint and weak.
That was my life: pathetic, faint, weak.
Then I was going to die.
\end_layout
\begin_layout Standard
So I take this as evidence that there's a metric fuckton of memories encoded
in my brain that are not directly accessible to my current waking state.
So there is more to me than my conscious awareness.
And it is my conscious awareness that types here.
Well, I've already talked about my reptilian brain, and the whirl of emotional
states that it is tied to.
All that Freudian stuff.
\end_layout
\begin_layout Standard
Odd, how some kids, high–school, college, get hung up with psychology as
a mirror–reflection insight into their own selves, while I was never tortured
in this way: I looked out into electronics and science and physics and
astronomy, like a sponger, I went there, and not inwards into neuroses.
And here I am, as an adult, getting a bit more neurotic as I age.
You know who some people suffering from mental illness get more normal
as they age? Well, perhaps being neurotic about the meaning of it all is
...
normal.
Here I am, five decades late in joining the party.
\end_layout
\begin_layout Standard
Where was I? Self–portraits, AI, immortality...
right.
So the point here is that most of me is already dead: childhood is dead
and gone, almost all of it behind an informational event horizon.
Fuck, what I ate yesterday for breakfast is behind an informational event
horizon.
So what exactly is immortality, anyway? Parts of me are dying, sloughing
off at very instant.
And every instant, I get to reinvent myself, all over again.
I get to pick.
\end_layout
\begin_layout Standard
So I guess that
\begin_inset Quotes eld
\end_inset
me
\begin_inset Quotes erd
\end_inset
is that spark of free–will that is me.
Now, I know some of y'all out there do not believe in free will, but my
readership here already knows that I think you're wrong, and I've already
articulated the reasons and I wont do it again.
So the me that desires to be immortal is a magic combo of the spark of
free–will, that I guess wants to keep on stumbling through life, that,
plus the baggage of accumulated memory that I've attempted to not forget,
to record and remember within my own brain, first and foremost, and then
secondarily in my writings and creations, and thirdly in my life–loggings.
That is

Is this diary really a part of me, or not? Well, of course it is a prosthetic

\end_layout
\begin_layout Standard
Oh, I should mention one story that I like to tell.
I was rowing one day, on Town Lake, taking a rest near the Radisson or
whatever hotel that is downtown, when it suddenly struck me: my rowing
shell is a wheel–chair.
An prosthetic device.
Aluminum and fiberglass, very good, very nice, but a pathetic replacement
for the arms that were cut off of me when I was born.
Some tragic accident that removed the oar–blades that used to be part of
me.
I am now a cripple, consigned to this piece–of–shit rowing shell that is
simply not as good as the body I was originally born with.
See, I was born with two elbows in each arm, one of the elbows is where
my wrist currently is.
That's where they chopped it off.
They chopped off my oars.
And then they stuck me in this rowing shell, as a consolation prize.
Phantom limbs.
This is what happened to me.
\end_layout
\begin_layout Standard
So what is this? This is my reptilian brain rewiring, forming new neural
connections for the motor control of muscles needed to perform rowing actions.
This happened after about a decade – I'd been rowing maybe eight, maybe
ten years by then.
I've read that something similar happens to race–car drivers: they have
phantom limbs too, but wheels and tires, in their case.
I can sort of understand this.
I had a '67 Cutlass with an anti–sawy bar and aftermarket shock absorbers
and large grippy tires, Something R60-240 and I drove around like a speed
daemon, a total asshole, on Long Island.
Went around 15 mph corners doing 40.
I eventually literally ripped a wheel off that car, after taking a corner
too fast: stress fractures in the frame weakened the thing to where one
of the A-arm joints broke off.
I had it welded back on, but stopped doing the sharp cornering after that.
But yes, although I did not quite have a phantom–limb experience with that
car, I can see how it almost became that.
I got very very very good at slolom driving.
Four–wheel drift and all that.
Fuck.
I remember going around that sharp corner in Lake Shore Drive in Chicago,
with my wheels pointing in the opposite direction from the corner.
No wipe–out, no accident, stayed in my lane.
Later in life, I did have a near–fatality on Mopac in Austin, with the
El Camino, when I gunned it on the onramp to the highway on a drizzley
day, and spun it out in a 720 before ending up on the shoulder.
I am fucking lucky no one hit me.
Those days are over.
Gone.
They are dead.
Only these words are here to record them, to take them out of the memory
hole.
So what is me, exactly, that wants immortality? The maniacal driver that
I've killed? I don't want to be that person at all any more.
Maybe in an infinite lifetime, it would be fun to go around a few more
corners with excessive speed, for the adrenaline rush, the speed–daemon
that is me, cause it was fun.
But I am not planning to risk my life any longer, and in the grand scheme
of things to do in life, this is no longer pressing or important.
The El Camino has not run in a decade.
It's been in a junk yard for maybe almost a decade.
It's over.
Its done.
The current me is ...
a well, genealogical preservationist, saving photos from the Syrjatowicz
family album on familysearch.org.
Thinking about how assembling genealogy is like doing jigsaw assembly.
I was also going to write about how hand–writing recognition and photo
identification is also jigsaw–like.
\end_layout
\begin_layout Standard
And the place I was going to go with this was that the assembly of these
connector sets is like, well, weight matrices in ANN's, except that some
of the weights are explicitly driven to zero.
So, rather than a clique, with some of the edge weights being very very
small, instead, a system with edge weights that are identically zero.
\end_layout
\begin_layout Standard
So, in this model, we still have hypergraph nodes and edges, but each node
is now a densely–connected ANN, and each link is a fairly fat interconnect
of connections.
But the whole thing is roughly scale–free.
The hypergraph nodes and links define how multiple different ANN's connect.
\end_layout
