Well I think there would be some obvious physical limits because of finite processing power like maybe a minimum distance, a maximum viewing distance, a discrete time interval and so on. Maybe some of the system would be modelled stochastically because being fast is more important than being accurate when simulating such a big system.
The main thing about the prevailing circumstances is that it showed idiocracy was way too optimistic. Their eugenics-ish narrative happened over way too long a period of time. We just needed a bunch of billionaires to poison the information supply.
