By the UDA. If you say "yes" to the doctor, physics emerges from
all computations, and even plausibly from those who do not stop,
which have a higher measure than those which stops.
I doubt that physics depends on what I say to anyone.
Hmm.... I am of course alluding to the content of the saying. Physics
does not depend on what you say to the doctor, but on the possible
truth that you might survive with the artificial brain.
But the question is, what if materialism is true and I say "yes" to
the doctor. I just don't see how saying "yes" to the doctor commits
me the rest of the argument.
Then you died, or you are in a simulation (of materialism, wmaking it
true in some local sense) or God is malicious (to be short).
And on the question of measure, when I write a computer program that
doesn't stop with an answer as I intended it is sometimes because it
has entered a loop. Aren't non-stopping programs like that going to
dominate the measure of computations by the UD?
Probably, not. The winners will be more like the computations of Pi or
sqrt(2). No loop, and some exploitation of the random noise, to
multiply locally the deep and interesting (in Bennett sense)
consistent and co-consistent (sharable) histories.
