You confuse perhaps with Schmidhuber's position, or some digital physicist (DP). But as I have explained many times here that this position does not work. Computationalism or digital mechanism (DM) is 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.
