I mean more that things people in a simulation can’t observe with great detail yet won’t be simulated with great detail until they can see that kind of detail, and by then, I assume technological advancements in the host world would have improved hardware to run on that allows that kind of detail to be simulated in a reasonable amount of time. Plus there’s also the ability of the host world to edit the simulation so that things that weren’t simulated in great detail when observed by people in the simulation before retroactively was changed, so that people inside always were able to see things in great detail in their memory, history, and other forms of knowledge from their points of view, but from the outside, things inside were changed minimally to make them consistent with any retroactive simulation conflicts. Not in a dystopian way, mind you, just in ways like “this very star was actually always a few light years away from its current position in the sky”, like small technical details that are smoothed over in the internal history as seen by the simulation inhabitants to match up with other parts of the simulation.
