As one of the leading researchers on consciousness, I'm surprised he's not mentioned at all in this. He is extremely fascinated by how consciousness goes away under anesthesia.
" But I’m agnostic about whether at the end of this programme of trying to account in physical terms for properties of experience, there will still be some residue of mystery left, something more to explain."

He doesn't believe there is a "hard problem" as described by others and dismisses that as shorthand for there being something mysterious we don't get. In a chat with Sam Harris the two argue that one out in depth.
I have heard him make the analogy to the Unifying Theory of Physics and admitting that even after all his work there could potentially be some aspect that could have weird quantum qualities, or is bound to dimensions of reality outside of perceivable 3d+t.
And while he doesn't agree with Douglas Hoffman as to there being conscience agents outside of space/time, he is fully in agreement with reality as perceived and currently observable being a whole cloth construction with our senses serving to adjust our individual construct.
