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
What does that mean?
A statistic is a function whose argument is a data set and whose
value is a number, e.g. Average is a statistic.
No problem. But that is not the statistics, just a result in some
statistical analysis.
You will need some measure on an infinite space to do the math. It
will usually contain a continuum of open set on some non enumerable
space.
I don't need anything. You're the one who's claiming physics is a
statistic.
Is not quantum physics, when use as a prediction tool, a statistic?
No. A statistic is a function of data, not a prediction from theory. A
theory may be statistical in that it predicts distributions from which
data samples may be drawn, as statistical mechanics may predict the
distribution of pressure and temperature of a gas. But pressure and
temperature are averages of samples, i.e. statistics.

(although it's not clear what "statistic" you mean...or is it just
metaphor).
It means the same as in the WM duplication, except that your
relative continuation is all computations (including all oracles)
going through your actual state. Cf step 7 of the UDA.
And if we compute the statistic we can compute our experience.
The net result is not computable, like with a coin in practice, or
like with a quantum coin in both theory and practice. We can compute
the distribution, but not the outcome per se of the experience.
