You confuse perhaps with Schmidhuber's position, or some digital

the idea that "I" am a machine, and by the first person indeterminacy,
and the way the laws of physics have to emerge from computations, the
physical universe (nor the fundamental reality) cannot be described
entirely by a computation. On the contrary it is a sum on an infinity
of computations.
If the universe is a computation, then "I" am computable, but then it
cannot be a computation (by what I say above, it is not obvious). So
with comp, or without comp, the physical universe is not a
computation. With comp, the laws of nature are not computable, or have
strong non computable components.
DM -> ~DP
DP -> DM,
So DP -> ~DP, so ~DP.

This confuses me. When you say the universe is not computable, you mean
it is not the process of computing a function. But you think it is
generated by a UD. Right? In other words, you are saying what a UD
does is *not* a computation.
