    That is mechanism, but then you inherit infinitely many
    body-representation in arithmetic, and the mind-body problem
    becomes in part a justification of the appearances from a
    statistic to all computations going through our brain. Then
    incompleteness explains what this take the shape of a quantum
    reality.




    This is substrate independent - the fact that a brain is
    physical is beside the point. You could implement a brain in
    software, and insofar as the same kinds of information
    processing occur, it would be conscious in the same kind of way.

    Only if it exists in the same kind of world.


Church-Turing implies that the world is irrelevant, so long as it is possible to build a computer in some universe, it is possible to instantiate/access any conscious state from that universe.

But the same inference implies that all universes are the same.  If a universe is just whatever can be computed then there are no different universes and to say the physics of the universe is simulated and "not primary" is the same as saying everything in the universe is simulated and not primary.  This the end point of everythingism in which it devolves into nothingism.

  This is little different from saying you could have a representation of the first 100 binary digits of Pi in many different kinds of universes, so long as their physics allows for digital representations.

Deep-Blue running on a computer in this universe is the same Deep Blue as one running in an a computer in the Game-of-Life universe, or on a computer in an alternate (of the 10^500) other string theory universes. CT implies it is impossible for any software to determine its underlying hardware, and this in determinism extends to the underlying physics of that hardware.'

    I find this idea compelling because it makes the link between
    brains and consciousness without requiring matter, and provides
    a framework for understanding consciousnesses of other kinds of
    machines. All that's required is to assume there is something it
    is like for computation to occur.

    Yes. Then it is sad that so few people are aware that the notion
    of computation is a purely arithmetical definition, so that we
    don’t need to assume more than Robison arithmetic. Worst, we
    cannot assume more, without exploding the number of aberration
    histories.

    Doesn't this worry you, that you are trimming your theory to get a
    desired outcome?   Is it empiricism?

    This makes mechanism testable, by comparing the physics emerging
    from the self-referential statistics on all computations with the
    inferred physics. And it match well, were physics itself miss the
    relation with the first person perspective, necessarily (assuming
    mechanism). A materialist has a way out: to invoke infinite to
    make the link brain-mind one-one, which it cannot be once we do
    the digital truncation.

    That's only because you are assuming the mind is infinite...which
    seems a little arrogant.
