When I see an old movie, like from the ’40s or ’50s or ’60s, the people look so calm. They don’t have smartphones, they’re not looking at computer screens, they’re taking their time. They’ll sit in a chair and just stare off into space. I think some day we’ll find our way back to that garden of Eden.

I like a book better if I can't predict what's going to happen.

Science fiction writers put characters into a world with arbitrary rules and work out what happens.

I think dry nanotechnology is probably a dead-end.

The world is colors and motion, feelings and thoughts and what does math have to do with it? Not much, if 'math' means being bored in high school, but in truth mathematics is the one universal science. Mathematics is the study of pure pattern and everything in the cosmos is a kind of pattern.

A computation is a process that obeys finitely describable rules.

The churning of a human mind is unpredictable, as is the anatomy of the human heart.
