> I find the idea of a universe with a discrete substrate both natural and compelling. I really like the idea of a finite, ever growing, and totally knowable universe. What Wolfram is searching for. The universe was a small finite graph at the beginning (which we can possibly know by looking at the sky), and it grows since that, according to some deterministic rules. This means that the universe is perfectly replayable, we can replay history, observe the thoughts of famous people, and such.
