Just wanted to add that this is an absurd discussion to even have in the science subreddit, because David Chalmers is not a scientist, and has no understanding of the workings of the brain (or else he would realize that conscious experience is fully explained via physical means that can be understood and observed). Chalmers's "hard problem" only presents difficulty to people without knowledge of neurology and cognition...because people with knowledge in those fields can and have elucidated the nature and origin of conscious experience via purely physical means.
