Or they'll figure out how to run good simulations once and copy paste it as desired? It wouldn't require them to be "exceedingly conservative", just a reasonable approach to their hardware and software. Again, that's assuming their reality looks anything like ours. This is the real problem with these discussions, we're speculating about the motives of entities we cannot even in principle have any information about. By the way, you might want to figure out how much you're actually worried about breaking the simulation, since you acknowledge that corruption would be a problem. Reasoning from human simulations, as seems to be your wont, do you think that risk of corruption is small enough to be so gung ho about messing with things?
