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.
