If we suppose that many natural phenomena are in effect computations, the study of computer science can tell us about the kinds of natural phenomena that can occur.

I like to do things that are surprising and different.

It's tedious to watch something very obvious being worked out, like a movie that's not particularly good and after about half an hour you know how it's going to end.

If you think of your life as a kind of computation, it's quite abundantly clear that there's not going to be a final answer and there won't be anything particularly wonderful about having the computation halt!
