It’s an interesting description of the space of computation and I quite enjoyed this article even though, as many, I have issues with the way wolfram participates in science. Certainly what he is describing can be a way to view the universe but that is somewhat trivial. It is not surprising that you get something like the universe when you start considering universal computation. The fact that we can write down e.g. equations of motion means there is a Turing machine that computes it. The real test is whether this perspective is useful in the sense that we can predict properties of the universe with it. That test is still out and until it’s addressed there is no way to evaluate or criticize this model. It’s too flexible to be useful at this point.
