What I can distill is that a simulating universe may be computationally stronger than the simulated universe, and not computationally equivalent. However, given Church-Turing theorem (ie, the simulatung universe does not need to be in a higher computational class to simulate equivalent universes), you can make a similar argument. What is the likely computational class of the simulating universe, given a class X of the simulated universe
