For the algorithm to work in many dimensions (XML tags), I feel like it must be a simple algorithm.

Rule 110 is known to be Turing-complete. https://en.wikipedia.org/wiki/Rule_110

I have a feeling that Rule 90 is the most efficient algorithm: the Sierpiński Triangle, self-sacrifice, infinite recursion to a perfect pattern. I'm not mathematically talented enough to prove that though.

Please come to chat about A New Kind of Science on Facebook! A couple of weeks ago I noticed that the page didn't exist, so created it. Hopefully Wolfram doesn't mind. We stand on the shoulders of giants.

I'm no physicist, but doesn't the Standard Model fit on a few pieces of paper? That the universe has rules that are a lot simpler than the behavior that emerges from those rules doesn't seem like novel claim. Wolfram's idea to examine the universe by exploring CA-space is the novel part I think.

Yea, the fuzziness comes from protons shuttling about, tunneling around, electrons moving in cycles with phosphates. It's all just vibrating, bumping and bumbling about. I remember how blown my mind was when I first learned that all reactions catalyzed by enzymes would have happened anyway given enough time and the enzymes just tune the systems to work in concert in a time frame conducive to life.
