That is not obvious. Have you understand the first person indeterminacy (step 3 in the sane04 paper). This imposes a sort of random oracle to the first person associated with the infinitely many computations going through their actual state. It is hard in that case to prove that non computable processes are not available, even to local observer. But I agree that except for the quantum randomness there are not much evidence for more on this.
