So it would not change the indeterminacy, as he will not immediately see that he is in a simulation, but, unless you intervene repeatedly on the simulation, or unless you manipulate directly his mind, he can see that he is in a simulation by comparing the comp physics ("in his head") and the physics in the simulation. The simulation is locally finite, and the comp-physics is necessarily infinite (it emerges from the 1p indeterminacy on the whole UD*), so, soon or later, he will bet that he is in a simulation (or that comp is wrong).

But if it is sufficiently large he won't find it is finite.

Hmm... OK. But he will soon or later. We are talking "in principle", assuming the emulated person has all the time ...

Finite or computable (Recursively enumerable).

would imply comp is wrong. In a finite world it seems it would be even easier to be sure of saying "yes" to the doctor.

I don't know how you can know that the universe if finite. But comp makes it non finite (and non computable), so if you have a good reason to believe that the universe is finite, you have a good reason to believe that comp is wrong, and to say "no" to the doctor. That *is* counter-intuitive, but follow from step 7 and 8.

I think you equivocate on "comp"; sometimes it means that an artificial brain is possible other times it means that plus the whole UDA.
```

Comp is where UDA is valid. By comp, according to the degree of understanding of the UD-Argument or the person I am speaking to, just means the hypothesis, or its logical consequences.
