That specific retrodiction came from Bruno's hypothesis which is that universes are generated by computation. What is computable is much less than all mathematics.

This is not my hypothesis. It might be Fredkin or Schmidhuber hypothesis, but not mine. My hypothesis is the hypothesis that "I am a machine", which is ambiguous, so I put it in the form of "yes doctor", which means that there exist a level such that my consciousness remains unchanged for a digital functional substitution done at that level.

And then the reasoning shows that the physical universe(s), are not generated by any computation. Computations generated my consciousness, and the physical universe is what my consciousness can predict from the mixing of determinacy and 1-indterminacy in the UD* (or sigma_1 part of arithmetic).

If I had written universes are indirectly generated by computation, would that have reflected your view?

But the presence of the word "generated" might still lead to confusion in this setting. Universe(s) are only observed, It is, or they are the 'natural solution' of the comp diophantine measure problem, which bear on the first person.

The only catch I see is that you wrote "can predict" instead of "must predict". Are you allowing for some agency here? m
I allow for agency, but not at that level. Indeed Matter, but matter only, is what the mind cannot act on. But the mind can act on the mind, and agency emerges at higher levels. No. The reason why "my consciousness" can predict, as opposed to "must predict", is the first person indeterminacy. It is the fact that I cannot know which machine I am, nor which computations executes the relevant states.

We can have partial information set, like, assuming bla-bla-bla, if I am duplicate in {W, M}, I will feel to be in M or in W. That is disjuncts. But by UDA-(step 8 included), I have to say at each instant I will be in u1, u2, u3, u4, ... that is the infinite sequence of programs generating my current state. They all compete in the measure, and "we" can only see the result of that from inside. Here the 1p and its invariance for the delays explains that such "results" never appear in the UD, but is on the border of UD*.
