"if recursively-simulated universes are possible it becomes vanishingly unlikely that we do not live in one"
That depends on the probability of a given universe or simulated universe to contain a simulated universe, and what limits there are with the complexity in space and time on each recursive simulation. I suspect that thermodynamics saves us here.
- Cushman 14y agoIt gets a bit metaphysical, but consider how many more possible universes there are in a universe which is likely to generate a recursive simulation than in one which is not. That is, the probability that the probability of being in a simulation is high in a given possible universe is, itself, high, ad infinitum, if simulation is possible, hence again why being able to simulate our universe is an important point of evidence.
