> Even supposing such systems exist They do, I gave examples. > Conflating simulation with real time I am not talking about real time, only about finite time for any Turing machine. No matter how fast you make your machine, I can ask for another digit of precision. As I mentioned earlier, you are also bounded on how fast your machine gets to be much earlier than I'm bounded on digits. You'll be running my double pendulum until the heat death of the universe, and using all the mass energy available to do it. > The brain is a computer" is a very different claim to "the brain can be simulated by a computer" These are equivalent by the universality of Turing machines. You are in fact making this claim, even if you don't realize it.
