> ... Computable physics would be extremely useful. Yeah, undoubtedly, but that has nothing to do with it being true. Wolfram doesn't make the case, at all, that it might be true, nor does he suggest any reason a CA might be a better model than the Schroedinger equation, or a way of searching for CA oriented models. The fact that modeling physical equations is difficult on a Turing machine is probably telling you something interesting about nature, rather than telling you to dispose of equations as models of reality. The whole thing is about as useful as Tipler's idea that God is a supercomputer at the end of the universe. Maybe thought provoking for certain kinds of people, but not helpful at all in the business of figuring out how the universe works, or useful things to do on a computer. It's basically an exotic form of science fiction with a higher than average cognitive load.
