No one knows the complete function of sleep. Is it to reset the brain or give it more of a rest period? Is it for cleaning the brain of all the garbage protein? For me, talking about these things as a non-biologist is fascinating.

Nobody really knows what it would take to create something that is self-aware or has a personality. I guess I could imagine a day when perhaps, if we can understand how it works in the human brain, which is unbelievably complicated, it could be possible.

I am generally fascinated by what are the big, challenging questions - that's behind my curiosity.
