Platonism obviously implies non-computability, since non-computable functions mathematically exist. However, the claim was that we are in a computer simulation. A computer simulation is obviously computable. >The mystery with "naive comp" is that it > remains something apparently computable in our neighborhood. > And that "mystery" cannot be used as a straightforward refutation of > comp, once we look at the non trivialities of computer science and of > consistent self-referential discourses. > > If we bet on comp, then we can already bet we already live in a > simulation, the natural one which emerges from the "creative nature" of > the relations between numbers. The word "emerge" is often used to hide magic. What actually exists cannot emerge from mere truths. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
