The opinions are exactly the same than about LLM.
The argument that was actually made was "LLMs do not think".
B: But Y would also imply Z
C: A was never arguing for Z! This is a strawman!
Everything I've seen says "LLMs cannot think like brains" is not dependent on an argument that "no computer can think like a brain", but rather on an understanding of just what LLMs are—and what they are not.
Would you mind expanding on this? At a base read, it seems you implying magic exists.
AFAICT, your comment above would need some mechanism that is physically impossible and incalculable to make the argument, and then somehow have that happen in a human brain despite being physically impossible and incalculable.
Penrose comes to mind, he will die on the hill that the brain involves quantum computations somehow, to explain his dualist position of "the soul being the entity responsible for deciding how the quantum states within the brain collapse, hence somehow controlling the body" (I am grossly simplifying). But even if that was the case, if the brain did involve quantum computations, those are still, well, computable. They just involve some amount of randomness, but so what? To continue with grandparent's experiment, you'd have to replace biological neurons with tiny quantum computer neurons instead, but the gist is the same.
"Can not be measured", probably not. "We don't know how to measure", almost certainly.
I am capable of belief, and I've seen no evidence that the computer is. It's also possible that I'm the only person that is conscious. It's even possible that you are!
The concept of understanding emerges on a higher level from the way the neurons (biological or virtual) are connected, or the way the instructions being followed by the human in the Chinese room process the information
But really this is a philosophical/definitional thing about what you call “thinking”
Edit: I see my take on this is listed on the page as the “System reply”
Check out eg Dennett.... or ... his opionions about Searle; Have fun with eg... this:
"By Searle’s own count, there are over a hundred published attacks on it. He can count them, but I guess he can’t read them, for in all those years he has never to my knowledge responded in detail to the dozens of devastating criticisms they contain;"

If you were a mind supervening on the behavior of some massive time/space scale computer, how would you know? How could you tell the difference between running on a human making marks with pen and paper and running on a modern CPU? Your experience updates based on information transformations, not based on how fast the fundamental substrate is changing. When your conscious experience changes, that means your current state is substantially different from your prior state and you can recognize this difference. Our human-scale chauvinism gets in the way of properly imagining this. A mind running on a CPU or a large collection of human computers is equally plausible.
A common question people like to ask is "where is the consciousness" in such a system. This is an important question if only because it highlights the futility of such questions. Where is Microsoft Word when it is running on my computer? How can you draw a boundary around a computation when there are a multitude of essential and non-essential parts of the system that work together to construct the relevant causal dynamic. It's just not a well-defined question. There is no one place where Microsoft Word occurs nor is there any one place where consciousness occurs in a system. Is state being properly recorded and correctly leveraged to compute the next state? The consciousness is in this process.
Another issue is that the brain is overly complex for consciousness to just be received from elsewhere. Typically a radio is much less complex than the signal being received, or at least less complex than the potential space of signals it is possible to receive. We don't see that with consciousness. In fact, consciousness seems to be far less complex than the brain that supports it. The issue of the specificity of brain damage and the corresponding specificity in conscious deficits also points away from the receiver idea.
You can replicate the entire universe with pen and paper (or a bunch of rocks). It would take an unimaginably long time, and we haven't discovered all the calculations you'd need to do yet, but presumably they exist and this could be done.
Does that actually make a universe? I don't know!
The comic is meant to be a joke, I think, but I find myself thinking about it all the time!!!
The question is, are the people in the simulated universe real people? Do they think and feel like we do—are they conscious? Either answer seems like it can’t possibly be right!
Connect your pen and paper operator to a brainless human body, and you got something indistinguishable from a regular alive human.

Whatever that something that it actually does in the real, physical world is produces the cogito in cogito, ergo sum and I doubt you can get it just by describing what all the subatomic particles are doing, any more than a computer or pen-and-paper simulated hurricane can knock your house down, no matter how perfectly simulated.
A pen and paper simulation of a brain would also be "a thing happening" as you put it. You have to explain what is the magical ingredient that makes the brain's computations impossible to replicate.
You could connect your brain simulation to an actual body, and you'd be unable to tell the difference with a regular human, unless you crack it open.
I'm not. You might want me to be, but I'm very, very much not.
Of course a GPU involves things happening. No amount of using it to describe a brain operating gets you an operating brain, though. It's not doing what a brain does. It's describing it.
(I think this is actually all somewhat tangential to whether LLMs "can think" or whatever, though—but the "well of course they might think because if we could perfectly describe an operating brain, that would also be thinking" line of argument often comes up, and I think it's about as wrong-headed as a thing can possibly be, a kind of deep "confusing the map for the territory" error; see also comments floating around this thread offhandedly claiming that the brain "is just physics"—like, what? That's the cart leading the horse! No! Dead wrong!)
An arbitrarily-perfect simulation of a burning candle will never, ever melt wax.
An LLM is always a description. An LLM operating on a computer is identical to a description of it operating on paper (if much faster).
That simulated candle is perfectly melting wax in its own simulation. Duh, it won't melt any in ours, because our arbitrary notions of "real" wax are disconnected between the two simulatons.
If we don't think the candle in a simulated universe is a "real candle", why do we consider the intelligence in a simulated universe possibly "real intelligence"?
Being a functionalist ( https://en.wikipedia.org/wiki/Functionalism_(philosophy_of_m... ) myself, I don't know the answer on the top of my head.
A simulation of a tree growing (say) is a lot more like the idea of love than it is... a real tree growing. Making the simulation more accurate changes that not a bit.
I can smell a "real" candle, a "real" candle can burn my hand. The term real here is just picking out a conceptual schema where its objects can feature as relata of the same laws, like a causal compatibility class defined by a shared causal scope. But this isn't unique to the question of real vs simulated. There are causal scopes all over the place. Subatomic particles are a scope. I, as a particular collection of atoms, am not causally compatible with individual electrons and neutrons. Different conceptual levels have their own causal scopes and their own laws (derivative of more fundamental laws) that determine how these aggregates behave. Real (as distinct from simulated) just identifies causal scopes that are derivative of our privileged scope.
Consciousness is not like the candle because everyone's consciousness is its own unique causal scope. There are psychological laws that determine how we process and respond to information. But each of our minds are causally isolated from one another. We can only know of each other's consciousness by judging behavior. There's nothing privileged about a biological substrate when it comes to determining "real" consciousness.
I'm not against this conclusion ( https://en.wikipedia.org/wiki/Philosophical_zombie ) but it doesn't seem to be compatible with what most people believe in general.
Determining what is real by judging causal scope is generally successful but it misleads in the case of consciousness.
If I make a button that lights the candle, and another button that puts it off, and I press those buttons, then the virtual candle is causally connected to our physical reality world.
But obviously the candle is still considered virtual.
Maybe a candle is not as illustrative, but let's say we're talking about a very realistic and immersive MMORPG. We directly do stuff in the game, and with the right VR hardware it might even feel real, but we call it a virtual reality anyway. Why? And if there's an AI NPC, we say that the NPC's body is virtual -- but when we talk about the AI's intelligence (which at this point is the only AI we know about -- simulated intelligence in computers) why do we not automatically think of this intelligence as virtual in the same way as a virtual candle or a virtual NPC's body?
Real is about an object having all of the essential properties for that concept. If we take it as essential that candles can burn our hand, then the virtual candle isn't real. But it is not essential to consciousness that it is not virtual.
A candle in Canada can't melt wax in Mexico, and a real candle can't melt simulated wax. If you want to differentiate two things along one axis, you can't just point out differences that may or may not have any effect on that axis. You have to establish a causal link before the differences have any meaning. To my knowledge, intelligence/consciousness/experience doesn't have a causal link with anything.
We know our brains cause consciousness the way we knew in 1500 that being on a boat for too long causes scurvy. Maybe the boat and the ocean matter, or maybe they don't.
It might if the simulation includes humans observing the candle.
Thanks for stating your views clearly. I have some questions to try and understand them better:
Would you say you're sure that you aren't in a simulation while acknowledging that a simulated version of you would say the same?
What do you think happens to someone whose neurons get replaced by small computers one by one (if you're happy to assume for the sake of argument that such a thing is possible without changing the person's behavior)?
Build a simulation of creatures that evolve from simple structures (think RNA, DNA).
Now, if in this simulation, after many many iterations, the creatures start talking about consciousness, what does that tell us?
That's an assumption, though. A plausible assumption, but still an assumption.
We know you can execute an LLM on pen and paper, because people built them and they're understood well enough that we could list the calculations you'd need to do. We don't know enough about the human brain to create a similar list, so I don't think you can reasonably make a stronger statement than "you could probably simulate..." without getting ahead of yourself.
It's been kinda discussed to oblivion in the last century, interesting that it seems people don't realize the "existing literature" and repeat the same arguments (not saying anyone is wrong).
Yes, or what about leprechauns?
