We can come back on this if you are really interested, but shortly:
once we assume the computationalist hypothesis (in the cognitive
science/theology), then the picture you give is most probably wrong.
Physics keeps a better role in the sense that physics emerges from the
"whole of arithmetic/mathematic". If you want, the physical world is
not a special mathematical world as seen from inside, but the physical
world somehow is the sum of all possible mathematical world where you
are.
"we" are not *in* a mathematical structure, we are distributed in an
infinity of mathematical structures, and physicality emerges from the
interference of them.
Why a wavy interference? Open problem.
