The Hard Problem of Consciousness

There's a class of experiences that are well explained by materialists, neure science. The hard problem for vachames is why and how should any of that be identical to or associated with any kind of subjective experience whatsoever. David chalmer talks about this hard, easy problem distinction. I'm doing something else, which is saying, ok, there's phenomenology on one hand, and mechanism on the other hand. How do i explain predicted control the one in terms of the other?
