>To dive into this specific question: to me,
Exact same reasoning for me. But none of this invalidates the speculation that LLMs are conscious. The question was more rhetorical. It was to illustrate via self examination the amount of unreliable evidence you use validate the consciousness of other people. You have a sample size of one for yourself and you use fmris (which actually provide extremely little understanding of the human brain) as evidence of similarity therefore even though the fmri provides no evidence of consciousness if that thing it is reading is similar to my brain then maybe said thing is conscious. That's probably the best evidence available but it is also extremely weak evidence.
The rest of your argument is talking about self reports from other people who are "similar" to you which is similar to the fmri argument in which the fmri invokes similar patterns and people describe similar patterns of experience to you... which is weak.
The overall point is you come to your conclusion based off of weak evidence so the LLM is no different. It talks like us, it understands us, you don't know anything else about it... how do you know it's not conscious? All evidence, (albeit weak evidence) actually leans towards it is conscious and that is the same amount of evidence we have for people.
Strong evidence would be determining the formal definition of consciousness and demonstrating logically and categorically that humans fit the definition. But we have none of that for either the human or the LLM.
>Do LLMs experience human-like consciousness?
No that is not the question. No one in actuality believes this. The question is Do LLMs experience consciousness that fits the definition or our own intuition of what consciousness is. It's fundamentally clear to everyone that the LLM runs off of a very different architecture then a human.
>2. There are only two lines of evidence supporting LLM consciousness and the first is largely circumstantial,
Many lines of evidence exist. All circumstantial and all no different from the circumstantial evidence you posted yourself for humans.
>a) LLMs possess some abilities previously only seen in humans. Specifically high-level verbal fluidity and linguistic manipulation along with instantly accessing a vast and diverse breadth of pre-trained information using a wide variety of non-linear relationships across many dimensions. While that ability is shockingly impressive, completely novel and can be quite useful, it's still only vaguely circumstantial because replicating some previously human-only abilities isn't evidence for the existence of other human traits like consciousness/qualia
This is not very good evidence at all. language follows rules. The rules are complicated and hard to replicate but replication of said rules do not indicate that it is conscious and it "knowing language" does not fit our intuition of what is conscious. If you think that this is the basis the reasoning of people who speculate that it is conscious then you are extremely wrong. The reasoning is much deeper than this. I feel a lot of people like you sort of classify the other side as mere simpletons who have not yet at all considered all the basic details.
>I'd argue we couldn't have designed a system to be more ideal at playing Turing's 'Imitation Game' and convincing humans they are human-like if we'd intentionally tried to.
Valid argument. But then I'd argue it is possible that it plays the Imitation game to the extent where it actually imitates consciousness by actualizing real consciousness. You can't say it doesn't.
>b) The second line of supporting evidence for LLMs is that they generate text which can describe internal subjective experiences much like a human
You seem to be answering a question no one is arguing with you about. Again. No one claims LLMs are human. No one claims they experience consciousness the way humans experience it. The claim is they experience consciousness in the way our intuition defines it INDEPENDENT of the human centric experience.
> In short, LLM 'self-reports' cannot be taken at face value any more than the performance of an actor we've hired to pretend something and strongly incentivized to never break character.
This is not true. We have proof of LLMs telling the truth and being right. Just because an LLM lied in one instance doesn't mean it lies all the time. But humans lie too so it goes both ways.
>3. But to me the real clincher is the negative evidence against LLM consciousness/qualia. Unlike the philosophical puzzles around trusting human subjectivity, with LLMs we can directly look under the hood at how it works and the entire specialty of Mechanistic Interpretability exists to do exactly that (https://towardsdatascience.com/mechanistic-interpretability-...). So we know with a fair degree of confidence that, despite what they may say, LLMs do not experience qualia in the way that humans and even other mammals do (which we have insight on from 'looking under the biological hood' with fMRI, surgical and brain injury studies).
This is extremely false. Mechanist interpretability to the LLM is as what an FMRI is to the human brain. It is a blunt tool that provides us a very high level view of the what's going on. This is categorically true for humanity right now: We do not understand why an LLM does what it does. Some sources to confirm that:

It's funny how you cited Mechanistic Interpretability without understanding what exactly was interpreted. You just took their word for it without understanding what's going on yourself. Well I'm here to tell you that there isn't any actual understanding of the LLM because if there was... we'd be able to use mechanistic interoperability to categorically determine whether or not LLMs are conscious. Someone would have proved it. The fact that we are having this debate literally means mechanistic interpretability provides nothing definitive.
