Knowing how to build a brain is different from knowing whether that brain has consciousness in the sense that you or I do. The question of consciousness appears to demand new/orthogonal physics because according to our existing physics, there's no sense in which you or should "feel" any differently than a rock does, or a computer does, or Searle's room does, or a Chinese brain does, or the universe as a whole does, etc.

I don't believe in the hard consciousness problem. Yes, materialist. And yes, it might be that we can never actually put together the path of physical level to how it feels, just like we might never find the fundamental physical rules of the universe. At this time both our positions are belief.
