In physics? Yes, that is a theorem in the classical mechanist theory. But the mathematical notion of computation is classical, and with mechanism, we cannot assume a non classical physical reality/appearance. We must deduce it from the computations (which are executed in arithmetic, as the logicians know since a century). You seem to assume a physical reality, but this cannot work with Mechanism. > It may not fundamentally exist, and if it does there are then deep questions > on how quantum mechanics builds up this phenomena that appears classical.

Which for a computationalist would be like to assume some natural numbers do not exist. It makes no sense at all. You might need to read my papers for proofs of this, and have some knowledge in computability theory, notably to understand that computation is an arithmetical notion. I can give references. The quantum is how the digital see itself from inside the digital. Note that by mechanism, I mean the hypothesis that the brain is Turing emulable (consciousness is preserved through a -digital brain transplant). It makes physics independent of the choice of the “ontology” as long as it is Turing universal, and that it has no induction axioms, nor infinity axioms. Note also that the physical universe becomes NOT Turing emulable, nor is consciousness (amazingly enough: I am aware this is counter-intuitive).
