Ummm. It seems like you were/are saying then that because AIXI makes an
assumption limiting it's own applicability/proof (that it requires that the
environment be computable) and because AIXI can make some valid conclusions,
that that "suggests" that AIXI's limiting assumptions are true of the
universe. That simply doesn't work, dude, unless you have a very loose
inductive-type definition of "suggests" that is more suited for inference
control than anything like a logical proof.

Hmmm. I don't get this. Occam's razor simply says
go with the simplest
explanation until forced to expand it and then only expand
it as necessary.
How does this suggest that the physics of the universe is
computable?
Or conversely, why and how would Occam's razor *not*
work in a universe
where the physics aren't computable.
The proof of AIXI assumes the environment is computable by a Turing
machine (possibly with a random element). I realize this is not a proof
that the universe is computable.
