Without making assumptions about the "purpose" of the simulation, I think that
the best we can do is guess a Solomonoff distribution of possible simulations
consistent with our observations. With regard to Bostrom, I think it is
unlikely that our descendants will run ancestor simulations. I think this
scenario is an attempt to guess something about the outside universe, which we
