If I'm computable, then so is my universe.

In his IMO excellent message Algorithmic TOEs vs Nonalgorithmic TOEs, Schmidhuber states that things one cannot describe, do not exist. If I interpret correctly, Schmidhuber was aiming, in this context, at _entire_ universes one cannot describe. I agree with this, but propose to extend this

I don't see a paradox here. In the latter situations, the volunteers are acting in accordance with different information, ie that of their measures. If they were not aware of their measures, they would have to assume a 50/50 chance of being A or B, hence would choose button 1.

The best you can achieve is an algorithm that outputs at least the computable infinite reals in the sense that it outputs their finite descriptions or programs. I am not sure I understand you here. Are you aware that the set of descriptions of computable reals is not closed for the
