Yep, that’s emergence, where the models of simple systems, interacting en masse, generate complexity/‘chaos’ more easily predicted by different models within that set of parameters/scale. Basically, it’s like modeling the behavior of fractals from their appearance instead of the underlying ruleset, because what the rules generate is unexpected to our human brains, so we need to make new rules that allow us to more easily predict things, even if those rules aren’t as perfect as the ruleset itself.
