It may not fundamentally exist, and if it does there are then deep
questions on how quantum mechanics builds up this phenomena that
appears classical. If quantum and classical realities are separate
and equal aspects of the world, such as what Bohr maintained, then
one must deal with objective loss of quantum information.
Which for a computationalist would be like to assume some natural
numbers do not exist. It makes no sense at all. You might need to read
my papers for proofs of this, and have some knowledge in computability
theory, notably to understand that computation is an arithmetical
notion. I can give references.
The quantum is how the digital see itself from inside the digital.
Note that by mechanism, I mean the hypothesis that the brain is Turing
emulable (consciousness is preserved through a -digital brain
transplant). It makes physics independent of the choice of the
“ontology” as long as it is Turing universal, and that it has no
induction axioms, nor infinity axioms. Note also that the physical
universe becomes NOT Turing emulable, nor is consciousness (amazingly
enough: I am aware this is counter-intuitive).
That turns your whole argument into a redcutio, sense at the beginning
it assumes one can say "yes" to the doctor and have one's consciousness
preserved by replacement of one's brain by a classical computer.
