        I think the idea of my proposal is basically correct, but it needs
refinement. It should be made more precise and possible to state more
simply and must be tested with a barrage of proposed implementations that
must be declared "true" or "false". But in research it is to be expected
that it may take several tries (and maybe several people) to get something
right. I'm being cautious because I've already tried and rejected a
number of ideas that seemed good at the time.
        Currently it has not been proven that the problem can be solved or
that my proposal does so, and it also has not been proven that this is not
the case. It may well be impossible to either find a solution or to prove
that one does not exist.

        I don't see much difference is this respect between the 'math' and
'physics' versions. You still want a 'math' computation that simulates
the universe to implement a brain computation, so you need the same kind
of solution to the implementation problem. Without this you have almost
no chance to get the right predictions but the universe is less complex
than the brain.
