For clarity though, I don’t mean literal predictability, I mean relative predictability from the individual’s perspective, which for some actual means life being predictability unpredictable; to some degree, I am, in part because I value the chance to improvise, but anyone that knows me would say that’s predictable.

As for population migration, statistics I had heard before, was roughly half of world’s population doesn’t move more than days walk from where they grew up and remaining in a given area is rarely tied to personal or regional opportunities or threats. Clearly my understanding might be wrong or things like climate change might force people to move; for example, roughly billion of the eight billion people on Earth will likely be displaced by climate change.
