Can a Turing machine of any sort truly indistinguishably simulate a nondeterministic system?
If a Turing machine can truly simulate a full nondeterministic system as complex as a philosopher but it would take dedicating every gram of matter in the visible universe for a trillion years to simulate one second, is this meaningfully different than saying it cannot?
I suggest the answer to both questions are no, but the second one makes the answer at worst "practically, no".
My feeling is that consciousness is a phenomenon deeply connected to quantum mechanics and thus evades simulation or recreation on Turing machines.
