Not really. Just subjective aberrance. Like seeing a white rabbit with
clothes and looking at his clock and saying "too late, too late". It
is physically and computationally possible, but occurs empirically
only in dreams. That is what remains to be explained if we bet on comp.
My query is that, since we only ever observe the environment to be
in accord with physical quantum law, how can a purely arithmetical
environment, which necessarily includes all possible computations,
give rise to only observations which are self evidently observations
of a physical environment, and a quantum environment at that.
Yes, that's my point. That is the question which we have to solve if
we take comp seriously into account.
QM solves the problem by phase randomization (Feynman).
Comp should solve the problem by the quantum logics related to self-
reference, and their non trivial semantics.
And if just one comp white rabbit remains and is located on the dark
side of the moon, we have to take a look there. If the white rabbit is
there, comp is confirmed, and if it is not there comp is refuted.
