In any case, A New Kind of Science is a wonderful book, and I'm still absorbing its teachings.

Computations are everywhere, once you begin to look at things in a certain way.

Now, being a science fiction writer, when I see a natural principle, I wonder if it could fail.

Our bodies are the time machine.

A little-known truth: Every aspect of the world is fundamentally unpredictable. Computer scientists have long since proved this.

For me, the best thing about cyberpunk is that it taught me how to enjoy shopping malls, which used to terrify me. Now I just pretend that the whole thing is two miles below the moon’s surface, and that half the people’s right-brains have been eaten by roboticized steel rats. And suddenly it’s interesting again.

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.
