> the idea is that if* we're in an ancestor simulation, then "they" will make the rules as close to theirs as they computationally can. Why ancestor simulation? Why else would "they" spend all those resources?*

This always struck me as the most WTF simulationist assumption. To the degree we simulate our ancestors, today, it’s in games. Given an infinity to ponder and simulate, it strikes me as ludicrous to assume even a significant fraction of computer power would go to ancestor simulations.
