I think dry nanotechnology is probably a dead-end.

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.

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

Traditional science is all about finding shortcuts.

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

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

Intellectually, perspective [drawing] is a breakthrough, because here, for the first time, the physical space we live in is being depicted as ifit were an abstract, mathematical space. A less obvious innovation due to perspective is that here, for the first time, people are actually drawing pictures of infinities.
