      Computationalism (the idea that everything in existence is fully characterized by states and transition functions) is

      Where this is not boringly obvious is the non-classical realm of quantum mechanics. The entire value proposition in quantum computing is that it can perform a kind of computation that transcends classical computation.

      QM is still a computational theory, just not classical. It always comes down to a big table of numbers, then your Hamiltonian comes along, and you get a new table of numbers. (I think that the universe may be digital, but that is a much stronger hypothesis than computationalism.)

          When you say digital, you mean discrete? Yes, that's a stronger statement. Does states and transitions imply discrete? It seems like it does! What does computational mean? Meaning that there's a previous state in time that leads to the current state?

          The general form of computationalism encompasses continuous transition functions, i.e. even though General Relativity is hypercomputational due to its continuity, it is a computational theory. (Personally, I bet on digital physics, but yes, that is a much stronger statement.)
