​Can you think of an example of a brain performing an analog computation,
or for that matter ANYTHING performing an analog calculation? I can't
because I can't think of anything that can be in an infinite number of
physically discernible states, and physics is needed for anything to
perform any calculation.  ​

​It's a bad idea to invoke new physics to explain a mystery ​unless there
is a very very *VERY* good reason, and in this case the new physics
wouldn't even solve a mystery. Why on earth would non-computable stuff be
more conscious than computable stuff? Most numbers on the Real number line
are non-computable and as a result do not and can not even have a name, are
they more self aware than a computable number like 1/3, the square root of
2, PI, or e? And physics can provide answers to problems, but
non-computable "physics" can not by its very definition, so what's the
point of it?
