With Mechanism, physics has to be the same for all “observers” aka universal machines, and indeed physics has to be independent of the initial theory (phi_independent, or “machine independent” in the sense of theoretical computer scientist (recursion theory does not depend on which universal machinery we talk about).

Indeed, physics becomes simply the “measure one expectation” of the universal machine on all computations going through (any) of its states. All the rest will be contingent and can be called geographical and/or historical. Our mundane consciousness requires long and deep histories.

So what expectation has measure 1.0?  Can you show that it includes conservation of energy-momentum for example?

You should revise the basics. The answer is no of course. There is not yet energy, physical time, … It is not even on the horizon.

Soling the mind body is not simple. But physics as metaphysics is simply wrong with mechanism, so to solve the mind body problem, there is no other choice, unless you know a better theory, of course.

Of course there are other choices: (1)  Mechanism is wrong

Sure. That is what we can test. It fits well the fact until now, unlike the materialist metaphysics.



(2) Your argument is wrong



Of course, that remains always a possibility, but you cannot assume this, you have to find the mistake.

One mistake is in inferring from the possibility of "accidental" implementations of computations instantiating conscious thoughts that no physical implementation is required at all.  Another is supposing that an "ideal machine" that knows/believes/proves every theorem of arithmetic is a reasonable model of conscious thought.
