I find reading Chalmers to be irritating. His first premise is dualism. If you read his original paper on the hard problem you'll find basically every statement presupposes this fact and then concludes this fact. It's maddening. Dualism cannot be assumed apriori.

There are several good rebuttals to Chalmers in this collection of essays: Explaing Consciousness: The Hard Problem: https://www.amazon.com/Explaining-Consciousness-Problem-Jona...

One of the best IMO is Thomas W. Clark's functional identity hypothesis that says that experience is _equivalent_ to the processing system. Basically, this is what it feels like to be a human brain.
