True. We probably self selected to be this way.
But mostly due to the lack of access to general knowledge. Maybe nature optimized humans to the wrong outcome.

Nature tends to hedge its bets vis a vis the outcome, though. If we end up in some kind of nuclear apocalypse and have to build the species back up from pretty much scratch then it'll be a good thing that nature kept around a lot of this old-school stuff.
Humans are just a temporary species in the history of time. I don't think it is going to repeat it, even with our current skills. Pretty much like the dinosaurs never really came back.
