I think the right question to ask here is the one about the instinct of self-preservation. Philosophical materialists (like Dawkins et al) would argue that all other aspects of consciousness are deducible from that. The complexity of decision making in survival strategies would sooner or later require some fuzzy logic and may very well spark the very thing that we call consciousness. We also wouldn't be zombies as kindness and positive social interaction would prove to be beneficial survival strategies.
So, would a system complex enough develop such an "instinct" for self-preservation out of itself? Did such systems merely emerge on this planet because of the usual evolutionary processes?
Most everything you're saying here relates to the "Easy Problem". Nor is there any reason that philosophical zombies would be exempt from the need for effective fuzzy logic and the exhibition of kindness.
Two things:
- Consider the Hard Problem.
- Consider the concept of proto-consciousness.
Proto-consciousness goes a long way towards making the Hard Problem seem tractable. Everything else just doesn't even come close.
