alt Hacker NewsI think you may be overstating this. The archeological evidence is pretty clear that prehistorical lifestyles weren't just small tribes slaughtering each other, and that there was a lot of variety and complexity in the way prehistoric societies organized themselves. Also, there are some societies that exist in 2025 which proved scary enough examples of what's possible.
There are also societies which have blatant arbitrary authoritarian rule which seem to be well in the 21st century. I doubt that faith in the rule of law is the only thing keeping our societies together.

Well, that's sounds quite logical. When you kill people, they usually fight back. Very strongly fight back. So you have to expect something big to make it worth it. But small very undeveloped tribes had nothing of such, so they have no incentives to slaughter each other.
