Some philosophers, namely Bentham IIRC, have argued that a human being without any experiences would have no intelligence. If you raised a human in a test tube and removed all their sensing organs, but otherwise allowed their mind to develop through the stages of maturity, would they have anything interesting to think? Would they have a sense of self, or an imagination?
I've always tended to agree with the argument that a human mind's feedback loops and subsequent responses are grounded purely on training datasets. Without a childhood of some kind, I suspect that you cannot have a person.
I find Myself often frustrated with the quality of arguments against AI qualia because they appeal to statements about the human mind which are quite controversial in the field of philosophy, and I am frequently on the other side of those statements than the person making them. I have yet to hear an argument against AI qualia that identifies an absolute ontological difference between humans and LLMs other than complexity.
Also, I'm uninterested in debating AI consciousness. I only want to discuss AI qualia. I don't think consciousness matters very much, qualia is much more important.
