Thanks for the reference, that looks like a pretty thorough review.

It seems to me that Chalmers already precludes the possibility of physical/materialist explanations with his claim, quoted in the first section:

> There is a logically possible world physically identical to ours, in which the positive facts about consciousness in our world do not hold.

This certainly doesn't feel obvious or intuitive to me. I would expect that someone with the same neuronal make-up will have the same experience.
