I am unable to afford the attention at the moment to assess this argument, that's to its credit. They demonstrate that they are aware of the implications of the varying descriptions of consciousness. Most articles I read on this topic turn it to be crude justifications of a naive ideology. This article is a cut above.
I will read it in more detail when I can afford more time.
A very interesting, dense article that will require multiple reads.
My only immediate comment is that it talks about qualia being "experienced" without defining what the nature of that experience is. And it kind of assumes that qualia have an ultimate physical manifestation - rather than being merely a rhetorical device.
Also, this site would really benefit from an rss/atom feed.

Denial of Qualia has long been an outlier position in the philosophy of mind, so this is not altogether surprising. (This is saying nothing, of course, about whether it is true or not.)
I don’t know that I’d call it that much of an outlier position. Compatibilists, functionalists, and plenty of physicalists in general would deny that qualia exist or that they’re a well-defined notion.
The existence of qualia does not mean the existence of moral facts.
An llm is in principle implementable with a large lookup table where the prompt is the hash. And it can be implemented in an emulator running an emulator running an emulator of the operating system the llm app runs in. How far are you willing to stretch this substrate idea?
I'm so bored with the "are machines conscious" debate. The only thing it has proven is how desperately humans will continue to move the goalposts to the point of ontological collapse in order to preserve their internal sense of primacy.
You don't want to call machines conscious? Fine. Call it quasiconscious, semiconscious, technoconscious, whatever makes you feel alpha human, and move on to our current reality where we confront the existence of thinking machines rather than footnote it into obscurity.
I fully agree with this. I find it strange how quickly the novelty of AI chatbots has passed. This used to be a thing of science fiction, that people dreamed, fantasized about. Now they are everywhere, people rely on them for the most mundane of tasks, and the only debates happening about them are - is their water use efficient enough? Is this CEO likable enough? There seems to be no sense of wonder. Do androids dream of electric sheep? Do humans still dream at all?
Most sci-fi is about genuinely sentient AI, and we are far from that. There is no sign of any intent or internal motivation. If you know anything about machine learning, you know that the idea that LLMs have any form of consciousness is ridiculous. Humans just like to anthropomorphise, that is all.
> There is no sign of any intent or internal motivation.
I don't think that the way we frame the question about consciousness makes it easy to resolve.
But I do want to point out that humans are very diverse. There're many functional adults lacking any internal motivation besides getting food, sleep, and some kind of entertainment. There're millions of people who just act on external stimuli.
So the gap between the "least conscious" human and the "most conscious" machine might be more narrow than we expect.
We can’t measure the temperature of consciousness like we can the temperature of simulated snow.
As you write consciousness does not necessarily arise from computation, but it may, at least to some degree, we don’t know. We don’t have reliable methods of testing for the presence or absence of consciousness, or even a rigorous and agreed upon set of metrics to measure.
Where as simulated snow is most certainly not real snow at all.
This is exactly the thought-terminating cliché that I see everywhere, and it's driving me up a wall. We have absolutely no idea what consciousness is, but everybody is 100% sure that LLMs don't "have any form" of it.
Yes, I know about machine learning, but I also know about how natural biological systems learn. It is, just from what we know, very different, yes, but the crucial point is that it, also, has zero identifiable things that you could point at and say: oh, look, that over there is consciousness. So the fact that there is no such thing in an ANN proves nothing.
It is said that absent any input these thinking machines we are inert, quiescent. That they have no intrinsic motivation of their own.
Whereas we, along with at least some other mammals but especially humans, seem to be infinitely inquisitive about the world.
But our minds don’t exist in a substrate of hyper sterile rigid silicon form.
What if some of the differences between us and our silicon based machines are merely embodiment (senses both internally and externally oriented, limbs and locomotion, etc) plus the noise of biochemistry?
Would be very interesting to be a fly on the wall in the labs these experiments are, presumably, taking place.
Mass Effect distinguishes between AI, which is sentient enough to be a person; and VI (Virtual Intelligence) which is more like a conversational user interface. What we have built in real life may qualify as a VI by the Mass Effect standard, but it's a crappy one.
I never thought I'd have so much sympathy for Kate “Forgive me, Mr Data; I am not accustomed to work with non-living devices that… Forgive me again. Your service record says that you are alive.” Pulaski, but here we are.
> I find it strange how quickly the novelty of AI chatbots has passed.
I had an eye surgery last year. The first day after was magical, I felt like I was on acid because the entire world felt different.
I went for a checkup one week later and told the doctor the vision has gone down since. They checked and it was objectively the same as on the first day. They told me: "People get used to good vision very fast".
I like the debate because I've learned a lot of stuff about consciousness, thinking, free will, determinism, agency, intelligence, emergence, problems with reductionism, qualia, etc... Lots of these concepts may be related but it might just be a correlation.
For example, free will and determinism may be orthogonal concepts (compatibilism).
Determinism is interesting. It's mostly a question of 'deterministic in what context'.
Eg the rules of chess are written as if the players have free choice. Similarly, algorithms are often analysed as if the antagonist that provides the data has free choice (so we assume the worst case to be sure).
That's a very different non-determinism from assuming a probability distributions.
And different frames might be accurate depending on context. You might know what chess bot you are playing against and that chess bot might be a deterministic computer program, or might be a computer program that uses radioactive decay to randomise.
And as you suggested, free will is yet another kettle of fish.
Everybody wants to argue about whether machines are conscious, without even deciding whether other mammals are conscious.
My sense is that the whole machine consciousness debate really kicked off since LLMs started being able to spew out a bunch of words in a row that sound like they make sense. Since only humans could do that before now, and humans are conscious, therefore...
I don't think language has anything to do with consciousness.
I agree that the goalpost is moving all the time. But the whole debate is a red herring. We don't have a good definition for consciousness. I can't really quantify the difference between a bee and a dog.
Why though? There are only two reasonable reasons I can think of:
1. Scale. There's clearly a scale of consciousness (a jellyfish isn't very conscious but an ape is). Current LLMs are so small (on the scale of brains) that they must be not very conscious at all.
2. Structure. There might be some fundamental structure of computation that is required for consciousness that LLMs don't have yet. For example the ability to form memories (they don't really have that), or some structure of weights that gives consciousness.
My guess is it's definitely 1. and probably also 2.
But I don't think that means thinking LLMs are conscious is completely ridiculous, just a bit premature. I would not be surprised if they are conscious in 50 years.
The real question is how would we ever know that they are. The only reason we know animals are conscious is by direct experience, and we'll never have that for AI.
Anyway this blog post looks like typically worthless philosophy.
Even though we know brains are conscious it seems absurd to thing that there is some non-computational magic in the brain is the secret to consciousness.
There are some religious people who clutch at nonsense like quantum microtubules, but nobody has found anything real that would preclude pure computation from being conscious. (And yes that does have all sorts of mind-bending consequences.)
I appreciate the article, even though I disagree. The number of people who are absolutely certain of their position is just way too high.
Anyway, I do think the heart of the practical question is what distinctions between machine / human / other biological intelligences are critical versus incidental. In this article the meat of the argument comes only right at the end
> Digital computers employ signal quantisation along with a variety of other error prevention methods in order to neutralise holistic physical effects like crosstalk between circuits. The purpose of digital logic is to make computational output invariant to the underlying physics – up to some thermal noise floor. This discretises their behavioural space – perturb the electric field slightly and this shouldn’t flip any bits. This is great – this is what permits reliable, deterministic computing in a wide variety of physical environments. However, if what we are interested in is phenomenal introspection, these error prevention systems prevent the exact kind of holistic behaviour we value.
There could be something here, but I am not convinced. Why is "varies in behavior with respect to arbitrary perturbations" a critical feature of consciousness? And is this even true for brains? If a perturbation is small compared to a neural impulse, will it affect anything?
I think there are a lot of serious problems with this article but don't necessarily disagree with the conclusion, as such. I do think robots and whatnot might be conscious some day. (I am a bit outraged that LLMs, despite totally lacking free will, seem to gain moral patienthood based on their fluency with ethical philosophy. It's childish and misanthropic.)
However, the real issue, as always completely unaddressed, isn't attempting to make a gague-invariant theory of qualia, or even defining what "qualia" is (I am totally unconvinced it is an EM field, there must be an epigenetic component). The first step is defining what "consciousness" is! Is it awareness of qualia or awareness of reality? These are not the same thing. It seems significant that any animal I would call a little conscious, even ants, are capable of being startled or curious when their sensations mismatch or incompletely describe reality (and animals that lack any sense of curiosity are at most borderline conscious). Curiosity and surprise[1] seems hard to convey in an EM field. Qualia strikes me as a somewhat technical problem of neuroscience, and the "hard problem of consciousness" is unscientific BS. The simplest basics aren't understood, which leads to totally unhinged statements like "in some ways a thermostat is conscious" because in some ways it seems to fit the hard problem. But statements like that are ideologically motivated by a sort of tech futurism: rationally, we should be deeply skeptical of an account of consciousness which insists that clocks perceive the flow of time.
[1] There's an information-theoretic version of surprise which intuitively describes "surprising" data. A sudden bright light has high surprise and is certainly surprising. A sudden realization that the vine you're leaning on is a large snake might involve very low information-theoretic surprise... and is far more alarming. So how do you systematically quantify this second form of surprise?
Indeed a classic (upvoted!), but it presupposes that there is a theory of everything that can be used to perfectly simulate the universe, and I'd like to remind everybody that we still don't know whether such a thing exists. Nor do we know whether it's possible to simulate "just" neurons and get meaningful results on some higher level. People have been trying at that for decades, so far without success. (nice overview here: https://ccli.substack.com/p/the-biggest-mystery-in-neuroscie...)
> [...] but it presupposes that there is a theory of everything that can be used to perfectly simulate the universe, [...]
LLMs are nice here: we don't need a theory of everything to simulate them. You can indeed use pebbles on the beach.
Scott Aaronson said that in theory a finite look-up table can win eg a ten minute Turing test (any finite length is fine). Of course, to borrow his argument further, the naive table would be galactic in size. So the real magic is in being able to compress the responses of that table into something human sized / LLM-server sized.
> but it presupposes that there is a theory of everything that can be used to perfectly simulate the universe, and I'd like to remind everybody that we still don't know whether such a thing exists
Is it even possible that a complete simulation of the rules of this universe (let alone the content of it) could exist in this universe?
I am no expert but I did manage to read most of GEB [0] so I feel fully qualified to say that it feels like something Gödel would have opinions about?
[0] the honest nerd's "did sleep in a Holiday Inn last night"
As an analogy: you can have a zip archive that expands to itself. Or even more so: to itself (the simulation of itself in itself) plus something arbitrary (standing in for the rest of the universe).
It is entirely possible (if perhaps unlikely) that the correct theory of everything is a relatively straightforward expansion of the current standard model.
Thank you for the link to the post. It was a fascinating read and also entertaining.
After seeing the story of the fruit fly brain simulation I figured stuff like the nematode would be trivial.
The lack of active plasticity in LLMs causes a lot of frustration imo. Having agents make the same mistakes over and over and not be able to correct course without prompt engineering is the biggest symptom.
Obviously a static mind is more helpful from a performance perspective, especially if you consider model deployments into gateware.
Maybe this will be an inherent limitation to LLMs that won’t be solvable without a new approach.
I would argue that for the situation of the comic to occur, it's only necessary to have a theory of everything that's sufficiently good to simulate a universe that's close enough to ours that it's hard to notice the difference.
Our bodies could just be rocks on a beach, but whatever it is about us that is capable of observing the output of our own internal thinking (preventing us from just being p-zombies) is not contained within the beach.
Well, thermodynamics is considered pretty fundamental, and the second law of thermodynamics is pretty much all about information. (But your link already touches that.)
People also interpret the 'unitarity' of quantum mechanics to mean that information is preserved.
I think you're being downvoted because you're announcing it as an absolute truth, of which we do not have evidence.
However I am open to your belief (and not on religious or theistic grounds which I assume many people might think you're talking about) because people have (non-religious) experiences that lend to such possibilities.
I would suggest to focus further research on dogs! Why are they so much more inteligent than humans and machines! Dogs are the ultimate stage of the evolution!
They have the real photonic futuristic hardware you are looking for!
yes and no. In my opinion, consciousness is not a process (yes I think Descartes was wrong). The 'thing' that is conscious, whatever it is, is the thing that is capable of experiencing the world. It doesn't need to do anything else to be conscious. Panpsychism is the closest thing to anything that make sense to me (https://en.wikipedia.org/wiki/Panpsychism). This view also makes it possible to separate consciousness from intelligence.
Sounds like you might also be tending towards Illusionism (https://en.wikipedia.org/wiki/Eliminative_materialism#Illusi...) the idea that "Consciousness" isn't a real "thing", or even a real property of a thing, just the name we give to one pattern that emerges from adaptive reasoning systems.
I think that Illusionism and related philosophies will tend to be seen as "correct" once AI systems become more and more commonplace, and people will be forced to dismiss the whole concept of "consciousness" along with mind/body dualism in general as a massive category error that philosophers have been making since antiquity.
When you get down to it, philosophy of consciousness mostly exists because philosophers have assumed that because "mind", "soul", "consciousness" etc are nouns in our language, and that since nouns are "persons places and things" and mind is a noun, mind must be a thing, which is of course not how language works and not sound logic.
I believe I am conscious and that consciousness is a thing. I just don't believe there is a process where 'unconscious' things become conscious. So Panpsychism is a bit of a cope out. It's not a verifiable in any scientific sense and so can't be disproved. You could say that it's therefore a 'folk psychology' or a religious belief. But at the fundamentals of any word view (scientific or otherwise) are axiomatic beliefs or articles of faith and I think consciousness is best off living down there.
"we cannot be certain that the subjective experience which they [digital minds] may be having is like what we imagine it to be like"
It is even more interesting: we cannot be certain that other people have the subjective experience like we imagine it to be like. It seems to me that the rest of author's arguments implicitly assume that we can be certain about other people's subjective experiences, but if you take this assumption away the arguments can't explain why digital consciousness hypothesis is any different from the hypothesis that the Universe contains at least one person besides me.
I mean I see no point in proving that LLM is not conscious if your methods do not enable us to prove that there are at least two people who is conscious.
I haven't read the article myself yet as it's big and I haven't got time now, but I will as it looks like it might be very good. However, if you read just the very first paragraph you'll see that's exactly what the author thinks:
> Personally, I consider myself a physicalist, but I’m also a panpsychist – because physics doesn’t really seem to deal in hard absolutes, and I find it straightforward to consider that everything is conscious to some greater or lesser degree
Time for a thought experiment! Imagine there are 2 monkeys. One monkey genuinely believes it is a unique and special being. The other monkey is genuinely egoless, believes all monkeys are just a coincidental blob of matter with no fundamental claim to being special and that in some sense are all part of the same being. There is enough food for 1 monkey. If that is all the information we're getting, I would contend that the egotistical monkey is far more likely to be the one to eat the food.
You might easily be you because if you weren't it'd be an evolutionary dead end. Everything with the ability to make choices ahs to believe at some level that it has more of a right to exist than the systems they consume energy more.
Each consciousness is a universe on its own. Matter is just how those universes interact with each other. This is how quantum mechanics work in my idea, each observer affects the matter and quantum effects take most probable outcomes because of that.

Yes, our current systems are likely still to primitive to be properly conscious. Probably.
But I wouldn't rule out that ChatGPT 10 or Claude Fable 15 might get conscious.

Reminds me of this classic: https://xkcd.com/505/
Replace universe simulation with a LLM an it’s hard to consider a bunch of rocks shuffling on a beach as conscious.
Or alternatively, our own minds are simply (squishy, organic) rocks on a beach, which is quite humbling if you think about it long enough.
Indeed a classic (upvoted!), but it presupposes that there is a theory of everything that can be used to perfectly simulate the universe, and I'd like to remind everybody that we still don't know whether such a thing exists.

Yes, it is possible! See how a Quine is constructed.

As an analogy: you can have a zip archive that expands to itself. Or even more so: to itself (the simulation of itself in itself) plus something arbitrary (standing in for the rest of the universe).
There's also information in the compiler and the zip binary, without that I'm pretty sure it's not possible.
You can stick a full copy of the compiler and the zip binary into that archive, if you want to.
The 'intron' can be arbitrarily large.
You can add the complete schematics for your CPU. And the standard model of particle physics.
It is entirely possible (if perhaps unlikely) that the correct theory of everything is a relatively straightforward expansion of the current standard model.

I would argue that for the situation of the comic to occur, it's only necessary to have a theory of everything that's sufficiently good to simulate a universe that's close enough to ours that it's hard to notice the difference.
Our bodies could just be rocks on a beach, but whatever it is about us that is capable of observing the output of our own internal thinking (preventing us from just being p-zombies) is not contained within the beach.
The "whatever" part, in strict terms, would be information. Jury is still out whether that is a fundamental component of the universe or not: https://www.pbs.org/wgbh/nova/article/is-information-fundame...
Well, thermodynamics is considered pretty fundamental, and the second law of thermodynamics is pretty much all about information. (But your link already touches that.)
People also interpret the 'unitarity' of quantum mechanics to mean that information is preserved.
This makes no sense at all as soon as you start trying to define where the internal/external line actually is.
I think you're being downvoted because you're announcing it as an absolute truth, of which we do not have evidence.
However I am open to your belief (and not on religious or theistic grounds which I assume many people might think you're talking about) because people have (non-religious) experiences that lend to such possibilities.
I would suggest to focus further research on dogs! Why are they so much more inteligent than humans and machines! Dogs are the ultimate stage of the evolution!
They have the real photonic futuristic hardware you are looking for!
What the hell is "moral patienthood"? (Paragraph 4)
Are we conscious at hardware/cell level?
yes and no. In my opinion, consciousness is not a process (yes I think Descartes was wrong). The 'thing' that is conscious, whatever it is, is the thing that is capable of experiencing the world. It doesn't need to do anything else to be conscious. Panpsychism is the closest thing to anything that make sense to me (https://en.wikipedia.org/wiki/Panpsychism). This view also makes it possible to separate consciousness from intelligence.
Sounds like you might also be tending towards Illusionism (https://en.wikipedia.org/wiki/Eliminative_materialism#Illusi...) the idea that "Consciousness" isn't a real "thing", or even a real property of a thing, just the name we give to one pattern that emerges from adaptive reasoning systems.
I think that Illusionism and related philosophies will tend to be seen as "correct" once AI systems become more and more commonplace, and people will be forced to dismiss the whole concept of "consciousness" along with mind/body dualism in general as a massive category error that philosophers have been making since antiquity.
When you get down to it, philosophy of consciousness mostly exists because philosophers have assumed that because "mind", "soul", "consciousness" etc are nouns in our language, and that since nouns are "persons places and things" and mind is a noun, mind must be a thing, which is of course not how language works and not sound logic.
I believe I am conscious and that consciousness is a thing. I just don't believe there is a process where 'unconscious' things become conscious. So Panpsychism is a bit of a cope out. It's not a verifiable in any scientific sense and so can't be disproved. You could say that it's therefore a 'folk psychology' or a religious belief. But at the fundamentals of any word view (scientific or otherwise) are axiomatic beliefs or articles of faith and I think consciousness is best off living down there.
My cat is more conscious than whatever latest frontier model is out there, and it runs on a little bit kibble and water.
"we cannot be certain that the subjective experience which they [digital minds] may be having is like what we imagine it to be like"
It is even more interesting: we cannot be certain that other people have the subjective experience like we imagine it to be like. It seems to me that the rest of author's arguments implicitly assume that we can be certain about other people's subjective experiences, but if you take this assumption away the arguments can't explain why digital consciousness hypothesis is any different from the hypothesis that the Universe contains at least one person besides me.
I mean I see no point in proving that LLM is not conscious if your methods do not enable us to prove that there are at least two people who is conscious.
And if digital computers are conscious at the hardware level, the universe is conscious.
I haven't read the article myself yet as it's big and I haven't got time now, but I will as it looks like it might be very good. However, if you read just the very first paragraph you'll see that's exactly what the author thinks:
> Personally, I consider myself a physicalist, but I’m also a panpsychist – because physics doesn’t really seem to deal in hard absolutes, and I find it straightforward to consider that everything is conscious to some greater or lesser degree
Consciousness could be an emergant property too, of matter arranged in a certain way. Why am I me though? Drives me nuts!
Time for a thought experiment! Imagine there are 2 monkeys. One monkey genuinely believes it is a unique and special being. The other monkey is genuinely egoless, believes all monkeys are just a coincidental blob of matter with no fundamental claim to being special and that in some sense are all part of the same being. There is enough food for 1 monkey. If that is all the information we're getting, I would contend that the egotistical monkey is far more likely to be the one to eat the food.
You might easily be you because if you weren't it'd be an evolutionary dead end. Everything with the ability to make choices ahs to believe at some level that it has more of a right to exist than the systems they consume energy more.
I mean, we are as much a part of the universe as everything else. We're just dead star matter arranged in specific ways.
A part of the universe is objectively conscious.
I have yet another take on that.
Each consciousness is a universe on its own. Matter is just how those universes interact with each other. This is how quantum mechanics work in my idea, each observer affects the matter and quantum effects take most probable outcomes because of that.
That’s an interesting thought. I’ll try not to type too hard on my keyboard then
my keyboard enjoys a bit of rough play
And so are electrons.
The latter is easier to accept.
