OK.

I would have said that certain computations are selected out by giving
high relative measure for locally stable consciousness experiences, and
then those relative computations will defined what is physical from
inside. this explains (or at least makes it possible to explain) why
apparent physical laws are isomorphic to mathematical laws. The
physical would be the mathematical as seen from inside by mathematical
entities.

Consciousness would be isomorphic with relative or conditional average
on *all* computations, which can be made matematical by Church Thesis.
