SENTIENCE

Mmkay, is sentience/consiousness/ect quantum, chemical/electrical, or SPIRITUALLL?

Science isn't really about proving anything, it's about predicting. And if sometime in the future a "Theory of Everything" is created, which manages to correctly predict all fundamental interactions, is deterministic, and more elegant/simple than the current complex string theories and whatnot, then I'd think it likely that the universe itself is deterministic. I believe that such a theory should exist, but of course with our current knowledge it seems just as likely that the universe has a fundamental randomness to it.

Also, when it comes to the details, Penrose is saying a bit more:
Penrose and Stuart Hameroff have constructed a theory in which human consciousness is the result of quantum gravity effects in microtubules.

I'm not hostile to the idea of free will at all. Whether free will comes from some sort of randomness, or simply a lack of total knowledge, no one can deny that it seems to exist. Free will would be an illusion in a deterministic universe, but it would still seem just as real to the entities experiencing it. We certainly are robots, in a way; we are information processing machines. In computer science, there are enough examples of programs doing things their designers never expected. Determinism does not imply predictable behaviour, at least not once your system gets complex enough.
