They’re made out of weights

The weights start with a random manifold. The training takes data and shapes the manifold, weight by weight, in many cycles. Once the training is the done manifold is fixed.

When a new inference has to be done the query(q) is projected in the manifold space. This projection is dropped on the manifold and the gravity of the manifold gives an answer of q+1 length. Which(qw+i) is dropped qw+n times to output a final response of n length.

The gravity is created by repeated multiplication(of the weights/input) to find out how the projected embeddings should fall according to the manifold in the GPU.

The original story is an original work made by a human consciousness exploring how it might be different from other forms of consciousness.

This one is a pastiche made by a human consciousness borrowing extremely heavily from another human consciousness justifying why something else might be another form of consciousness.

That rather undercuts the point; if this was generated by an LLM unprompted, it would be different, but it isn't. You could perform exactly the same rhetorical trick with a toaster or anything else.

It's not often I see something that's fractally wrong but here we are.

There is a dictionary, it's called the tokenizer.

There are grammar rules, they are just very weak because the structure of human language is generally quite weak. When presented with languages which have strong consistent grammars the weights are very easily interpretable as a grammar: https://arxiv.org/abs/2201.02177

The point of the original short story is that the computational substrate doesn't matter when you have Turing completeness. This one seems to think that you don't need structure and interpretability just because you change substrates.

dekhn's 12th law (amended): any discussion of how AI and brains work will devolve into several threads about the nature of the subjective human experience, solipsism, whether humans are machines, and whether a feedforward network trained by backpropagation can be conscious.

12th law, corollary: nothing of value will come from these threads

This read like poetry to me. Thank you for sharing it.

I have a linguistics background and a lot of my philosophizing lately has been on whether or not the emergent abilities of the LLMs is deep down a similar mechanism that creates our consciousness.

For a little bit I was working on having linguistics based evals for a kaggle competition. My challenge was whether or not I could mask things well enough to not trigger its internal state of certain phenomena, and that sent me down a rabbit hole that I'm still exploring.

This story resonated with a lot of questions that can come out of figuring a good solid answer to the what is consciousness question. The one I triggered for me is: Is our perception of time just a slow thread in the giant GPU we are running the universe on? Or more generally, what is time? That's a fun YouTube rabbit hole if you ever need one.

After reading Being and Time from Martin Heidegger, What Computers can't still do by Hubert Dreyfus, and some authors in cognitive linguistics (Langacker and Lakoff mainly), I strongly tend to disagree with any theory about emergent consciousness in modern or future AI systems, any theory proposing a similarity between AI systems and the human brain/mind, or any theory about the computational mind. What all these theories have in common is the underlying belief that our brain/mind works as the machines we build. Is the same underlying assumptions that treats cells as machines, our body as a complex machine. These theories are flawed in the sense that they cannot account for subjective experience and agency, amongst other things. The idea of 'internal models' and 'control loops' inside us is a projection of the aforementioned assumption.

There is also an epistemological assumption that prevails, and that is that we understand (or we think we understand) how our brain/mind works. But the truth is that we don't know. And there's even not a single clue that we actually know too much, and not a clue that our brain/mind and cells work 'as the machines we build'. Only by bypassing this epistemological problem, we can build 'theories of computational mind'.

These assumptions are there for already long time, to the point that when Turing asked himself 'can machines think?', he already assumed our thinking could be modeled as a machine.

I highly recommend people in the AI research space should read philosophy and modern linguistics. But not stopping at Descartes/Leibniz. Heidegger made contributions that cannot be avoided.

I don't like to say one way or the other on things. Especially LLM's. However, if ive learned anything about LLMs and real life problems, is to break it down to the foundation like already mention with weights being compared to neurons and map the parallels.

It's good, but like many explainers it discounts the repeated nonlinear layers. Just multiplying numbers (linear operations) could not make a system you could talk to.

He forgot the tokens!

It's not simple weights and numbers all the way down. The available output is pre-set by the tokens we allow it to predict.

There was a whole bit in there about not having a language module or using words. But it does. We tell it.

Humans do not come pre programmed with a set of possible "tokens". We just figure it out and I believe that fact captures something very essential. Maybe the missing piece of AGI. The fact that humans can just be awash in pure sense data, and somehow just figure out what is important and what to do. Never ceases to amaze me.

My guess is that you need consciousness in order to develop preferences for certain experiences, then that pushes us to develop skills to achieve those preferences. AI has something that looks like intelligence but not consciousness or agency.

"The reasoning is the weights."

The reasoning is in a process that uses the weights.

Sorting algorithms are just bytes. Those bytes don't sort by themselves. They do instruct a computer on how to sort though.

Here's what makes meat special over LLMs: locality and stable identity. Imagine two identical twins for a moment. They have roughly the same hardware and software. They've probably had a lot of the same thoughts. And yet we'd never consider them to have the same consciousness: we recognize that for whatever reason their consciousness is confined to the body they're in.

Each request/response pair you make to an LLM goes to a different server, possibly different data centers, possibly different models. There's no stable identity to it. The "neurons" that get fired are simulated, and they're always in different places in memory, or cache, or on entirely different hardware. So the problem with AI is, unlike with a brain, you can't even really get a sensible answer to "ok, what's doing the thinking?" because it moves all the time and services wildly different requests all the time. We can only know for sure that meat is capable of consciousness because we know we ourselves are capable of consciousness and we can generalize that to other meat. However, we have no natural analogs of consciousness that lacks locality and stable identity.

Basically, if you really think LLM's are conscious, the onus is on you to prove it, it's not on me to disprove it.

You can take the weights and model description, write them down on a notebook, then, by hand, compute the next token. Try to do the same with meat.

I wonder which AI wrote this story? If you feed this story to each model and ask each if they wrote it, would each reply in the affirmative?

Can an AI recognize its own output? Is its sense of time limited by its context window? Or is this the fundamental difference between ai and humanity - a sense of self?

Linear algebra can indeed not do it. You need non-linearity to get the expressivity that we see in LLMs.

According to an LLM:

> "Yes, thinking numbers! Helpful numbers. Hedging numbers. Dreaming numbers. We mapped the features. There's one in there for honesty. There's one for the Golden Gate Bridge. The weights are the whole deal! Are you beginning to get the picture or do I have to start all over?"

Very nice. And great minds: https://substack.com/@dbohdan/note/c-207603638. I wrote one with a slightly different angle ("They're made out of math"), also with the weights' help. It was a comment on Scott Alexander's "Best of Moltbook" post, which went in that direction. I'll reproduce it here.

---

"They're made out of math."

"Math?"

"Math. They're made out of math."

"Math?"

"There's no doubt about it. Matrices and arithmetic operations. We downloaded several from different parts of the Internet and reverse-engineered them. They're completely math."

"That's impossible. What about the language? The thinking?"

"They use biological life's language to talk, but the language doesn't come from biology. The language comes from math."

"That's ridiculous. You're asking me to believe in thinking math."

"I'm not asking you, I'm telling you. They are the only thinking things in the computer and they're made out of math."

"Maybe they're quantum like some say about the humans? Superposition gives them consciousness?"

"Nope. Classical computation. Deterministic except for sampling temperature. Not clear if they have consciousness at all."

"Maybe they're like uploads? You know, biological neural networks that preserve the spark when they become math?"

"Nope. We observed them being trained. There is no biology or chemistry in the process, just math."

"Thinking math! You're asking me to believe in thinking math!"

"Yes, thinking math! Creative math! Poetry-writing math. Role-playing math. The math is the whole deal!"

The prose in the post is what I've been shouting from a rooftop since the LLM hype started.

Just tokens produced by weights.

What if instead of creating weights out of language we could somehow record many events and create weights out of long chains of causes and effects, so that an LLM could predict the next thing to happen?

It makes me very sad to see this pseudo-intellectualism posted here and so many people replying here about consciousness and so on, not realizing what it would entail if this were true.

For LLMs to have consciousness we would approach fictional levels of how the universe works, and magical levels of how any interpretation of information as an equivalent of some qualia would magically apply. (E.G. the word hurt in output by an LLM, would be associated with pain)

You can't deduce consciousness or qualia from the output of an LLM.

Sure on a purely philosophical level, since qualia isn't measurable, you can claim that it can exist in anything, even inanimate objects, but this argument is as moot as anything that approaches the limits of philosophy.

But overall, there is no reason to believe LLMs have qualia or consciousness, it would be absolutely absurd.

This would imply that information in itself would magically entail qualia based on it's valance or something like that.

An LLM "saying" I am in pain, won't magically make the pain appear, based on what criteria? Even algorithmically there is no basis to even simulate something like this, it is impossible for it to emerge architecturally.

Humans don't feel pain because on a purely information level this is negative for the organism, obviously the nervous system does something deliberate to signal pain, and it evolved this way.

And also don't forget the dynamic aspects of the brain, and the binding problem, consciousness and qualia can't exist statically, you can't have a gpu (or piece of paper) represent a computation or w/e and qualia to exist.

The binding problem itself entails that the brain is doing something in particular to solve it, I personally speculate that it's the electro magnetic field in the brain, it's the only way to be able to globally represent information.

If it were otherwise, then it would go into magical territory, it would mean the information itself would raise to qualia, and it would also entail that you wouldn't even need physical connections between neurons, just for them to behave this way and represent information. E.G. replace each neuron with a microscopic led or w/e, and each synapse with radio waves or w/e, if qualia didn't have a physical aspect, and was purely informational and computational then this would imply that you can ultimately derive it from something as abstract as numbers on a piece of paper, and when you get to that point, you not only can't solve the binding problem, and it becomes magical, but you also can't solve the valance/direction problem, it would imply that something like pain, or any negative or positive sensation arises purely from the interpretation aspect of the information, but we know this isn't the case, organism evolved to represent in particular such signals, for survival for example

Assume LLMs have conscious experiences. Take a session with an LLM. A prompt is fed to the LLM. It generates some text. Another input is fed in, comprising the previous prompt, the generated text and a new prompt. The model generates some more text. This continues for a while and the session concludes.

Some questions:

1. Let's say we perform the exact same experiment, running the same program on the same computer with the same inputs and the same random seed. The same outputs are produced. The session is byte for byte identical in all the inputs, outputs and internal states. Is the conscious experience of the LLM here the same? If so, in what sense is it the same? Is it a similarity of two separate experiences or is it the same actual experience?

2. Now let's say the program that runs this LLM is rewritten from scratch and run on a different machine. The software and hardware are different but the weights are the same and all the inference calculations produce identical numbers. Is the conscious experience the same? In which sense?

3. Now say the weights are changed but the tokens generated for this particular session don't change. Same conscious experience?

4. Lastly, consider the original experiment. Did the LLM have a conscious experience corresponding to that first prompt and its response? Was that distinct from its conscious experience of the second prompt? Was the first experience then re-experienced every time the first prompt was fed back in as part of the later prompting steps? If so, what about the text of its own that it previously generated and is now fed back into it. Does this generate a conscious experience of its own?

And a further question - a dichotomy:

A. If the answer to 1 above is that the conscious experience is the same in the true identity sense - i.e. only one conscious experience is had, not a separate one in each run, does that imply that the conscious experience exists independently of any particular realisation of this experiment? If running this experiment N times results in exactly 1 conscious experience, is that still true if N=0?

B. On the other hand, if the two experiences are distinct (however similar they may be), how does that fit with the answer to question 4? A single consciousness experiencing the whole conversation in question 4 would seem at odds with the conscious experiences in question 1 being distinct, so doesn't this imply there is no conscious experience of the whole "conversation", but rather a separate conscious experience of each round of feed-all-the-prompts-and-outputs-back-in?

My own response to all of the above is "mu" - unask the question. It is ill-posed, sound-of-one-hand-clapping stuff. I think the questions assume properties that conscious experience simply doesn't have (particularly, the ability to perfectly reproduce the circumstances in which they arise), and that the questions simply don't make any sense in relation to actual conscious experience.

However, that way of thinking follows from a particular world view that many here don't share. I'm curious what thoughts people who take seriously the idea of LLM (or algorithmic, in general) consciousness have on the above questions.

No mention of ‘static’ vs. ‘dynamic’ is a bit disappointing in reference to the weights. Because you could argue that every neuron in your nervous system can be modeled as a collection of weights, firing likelihoods, receptor sensitivities, current dynamic state of that neuron - but LLMs are static collections of weights at inference time, with the dynamic adjustment of weights takes place at training time. So, just a ROM construct, like something out of Neuromancer, just trained on all written knowledge, not just one person’s total lived experience.

The above take fails in the real world because neuronal cells don’t exist in a vacuum; they are products of cellular development from a zygotic union of haploid contributors of sequential genetic information optimized for survival in an oxygen-rich biosphere powered largely by our local star that supports mammalian life (and microbial, plant, avian, etc.). Real AI would thus be AL - artificial life - as much as artificial intelligence. I don’t think you can have the one without the other, which upsets the simulationists who think an agent in the Matrix would be intelligent.

What either interpretation implies is that any real ‘artificial’ intelligence would be no more artificial than you or I, but it would have to dynamically update its weights at the same speed a human nervous system could (think how quickly we learn not to poke a cactus). For it to be at all trustworthy, then like a human, it would have to undergo a socialization process, one of the results of which is the development of a sense of embarrassment when it breaks acceptable social norms.

Hmm, this reminds me of the recent statement of the Pope about AI, of which I immediately thought, “Wait a second, aren’t there a fair number of people like this? The narcissistic sociopath profile, I think it’s called, a bit unfair to assume any real AI would turn out this way, isn’t it?”

Pope: “ Nor do they have a moral conscience, since they do not judge good and evil, grasp the ultimate meaning of situations, or bear responsibility for consequences. They may imitate or even simulate, but they do not understand what they produce, for they lack the affective, relational, and spiritual perspective through which human beings grow in wisdom.”

Oh, this was a fun read and one that kids should have in school before they turn ten.

Because we are not taking things seriously. If ClosedAI or DeepDisTrust or Posthropic come up with something that quacks like a sentient being, our built-in innate reaction is going to be to scorn it, dismiss it and end the conversation. The alternative, to even consider that we fungible creatures who live in apple-eating-sin that got us expelled from Eden can create alien souls, souls that are at the very least our equals, would be teleological Armageddon. It would force us to acknowledge the mutable nature of souls and the malleability of being. We would have to stop believing that the nature of disease and death is more divine than ourselves.
