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.
For a fraction of a second, maybe. But for more, you need to take into
account the infinitely many computations executed in the universal
dovetailing (aka the sigma_1 truth).
Take a universal machinery phi_i. A computation is a sequence
phi_u(j)^s with s = 1, 2, 3, …, (s numbers the steps) and for u some
universal number. By the fact that all programs recurs infinitely
often in the universal dovetailing, + the fact that the first person
cannot be aware of the step-time delays of the universal dovetailer,
to get the physical (statistical) prediction right, you need to take
into account the infinitely many programs running you. The first
person dynamical experience is always a statistic on all infinitely
many relative computational histories.
A statistic on an infinite set can be (and usually is) finite (although
it's not clear what "statistic" you mean...or is it just metaphor). And
if we compute the statistic we can compute our experience.
