If this is a simulation then it’s pretty mundane. If civilisations had the power to simulate universes, i can imagine vast numbers of more extreme or interesting universes. Heavens, hells, dramatic and artistic experiments. The mediocrity principle coupled with the fact that we’re in quite a boring universe seems to indicate that either the majority of simulations are quite mundane for some reason, or we’re likely not in a simulation.
Given the immense size of our simulation and our relatively small presence in it, it could be that the simulators had no expectations of it becoming self-aware. It would seem that they simply picked some fundamental parameters (physics) and started it.
How do you know this universe is boring / mundane to a hereto unknown creator civilization? Maybe this universe is highly novel when compared to their experience?
