I totally agree. Humans and chimpanzees diverged millions of years ago and between then and, say, 50,000 years ago, people have been basically living in the same way: hunt, gather, use simple stone tools, live in small tribal communities in fierce competition with any other small tribal communities.

All of the evolution that makes us uniquely people and not just a monkey's uncle has prepared us for that kind of a life. It didn't prepare us for a world where we live in cities which we have the power to destroy with one atom bomb, where we can fly to the other end of the world in a matter of a few days.
