Proof that physics = witchcraft with equations.

Maybe programming (implementing simulations in programs) would be better.


Note that if Mechanism is correct, the physical reality cannot be emulated by a computer. The reason is that if “we” can be emulated by a computer, physics has to be reduced into a statistic on *all* computations,

Why "all".  We can only experience a finite number of thoughts/feelings/etc.

Brent

and that can be shown to be not Turing emulable, despite of course it has to be Turing Universal at least. The complexity of the physical reality  escapes the arithmetical complexity hierarchy, but it might not escape the analytical hierarchy. For consciousness, the complexity should escape the analytical hierarchy, and plausibly all possible hierarchies.
