I agree that our natural social organization is tribal, or familial (in tribal groups, there's a lot of overlap there), but then again, we aren't naturally designed to walk on the Moon either.

When you think about it, it's a frigging miracle that a mass of humanity like Tokyo or NYC operates anywhere near as smoothly as it does. Maybe we're on to something.

We're something radically new in lifeforms on this planet, no matter how many people tell us we're no different from the other animals.

An experiment in progress, with the internal contradictions you mention and a couple of others.

I hope we win. I want to see us get to the stars.
