As I have said before, the biggest challenge for quantum physics is to
explain the emergence of the classical world from the quantum
substrate, so that classical calculations actually get the correct
answers in those classical situations. If you do not believe that
these classical calculations are correct, then I advise you not ever
to drive your car on a busy road.....
There is no way a Hilbert space can become a classical configuration
space. If one sticks to a falsified theory (in the domain where you
can hide the shortcomings under the carpet) and cast doubt on a theory
that has withstood rigorous experimental tests, then it's likely that
attitude that's the cause of most problems.
That's what I mean by logic chopping. Everything is quantum therefore
every uncertainty is quantum uncertainty...therefore all insurance
companies should be studying Hilbert space. This overlooks the fact
that the classical world is far better empirically supported than the
quantum world and there is consistency between quantum mechanics and our
theory of spacetime. It is like Bruno's argument that starts with the
assumption that his theory is correct in order to prove that fundamental
physics (whatever that is) is wrong.
