However, Solomonoff induction needs infinite computational resources, so
this clearly isn't a justification.

The major drawback of the AIXI model is that it is uncomputable. To

My thinking is that a more-universal theoretical prior would be a prior

Oddly enough, one can make statements *about* uncomputability and
uncomputable entities, using only

For instance, one can prove that even if x is an uncomputable real number
