QM is indeed reversible (in large part), but using this to select
one branch by boundary condition, is still like a form of cosmic
solipsism to me. We can't refute it, and unlike most QM collapse
theories, we can't criticize it from locality and determinacy, but
that does not yet make it convincing compare to MW, and infinitely
more so in the comp frame, where we can't avoid the many "dreams".
It's just information from the future - which is exactly the same
thing as true randomness, and both are operationally the same as
FPI. That's why I think an advancement in QM interpretation would
be to derive probability. Comp provides an explanation of
randomness, but it's not clear to me that it implies a complex
Hilbert space.
It should, but even the orthomodularity quantum "tatutology" is still
non tractable.
So it not *yet* clear, but that question has been reformulated in
purely arithmetical terms. The arithmetical quantization []<>p (with p
sigma_1, and []p = Bp & Dp & p, for example. B = Gödel's beweisbar)
dtermine the answer, alas, still unknown.
