I'm surprised at how many people here seem to think there is something fundamentally special about the brain. It is marvelously complex, yes. Our understanding of how consciousness is derived from its processes is not understood at all. But it's just a thing made of atoms; there's nothing magical about it. Just 110 years ago, there was no way to explain how the sun had been radiating all the energy it does for as long as it had. Until E = MC^2, there was no known process that could account for it. Now, it's pretty mundane as far as physics is concerned. I see no reason why it won't be the same with the brain and how consciousness arises from it. In the end, it's just a chunk of matter operating in accordance to physical laws. Won't we figure it out, given enough time?
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
