    I wonder how much @stephen_wolfram's own thinking in terms of constructionist math instead of uncomputable math contributed to his alienation from mainstream physics.

        I don't think that particles hold us back any more than planets, and we need these descriptions in some contexts for the same reason. We just need to let go of both for foundational physics, and I agree that this is not controversial.

        I suspect that superpositional states are uncomputed functions. It may be very hard to do without that without letting go of the notion of particles altogether.

        I am not really interested in physics, but in ontology. For me, the most interesting question right now is whether we live in a hyper-computational (or even meta-computational) universe, or in a computable one. Few physicists seem to think that this question is deeply relevant.

        It all comes down to what questions one is interested in, which then informs the methodology. Scientific fields are started by questions, but defined by methods. The question of how to make a universe is of interest to very few people only.

        I still suspect that if our universe is natural (not deliberately created from within another, perhaps natural universe), its foundational principles must be very simple. But we live in emergent dynamics, digging down from observables will get us stuck between layers of emergence

        It is one of these riddles that we stare at and wonder about the single underlying rule, no?

        GR is quite obviously a theory of emergent dynamics (like thermodynamics), and QM a bit less obviously so. The SM has half a page of complicated code! Don't you think that the fractal of this universe must have a much more concise generator?

        I now think there is a class of universal function approximators, which can solve any problem that can be solved by a computational machine, and this class contains itself, and it also contains us. Given enough resources we can solve any solvable problem.

        There is not a single GUT, not even a hypercomputational one. You guys are an embarrassment. I fully expect that Deepmind will do it as a minor side project long before physicists have a clue.
