You know the early humans who lived in Europe 25k years ago? The ones with stone tools who carved thicc portable woman statues?
How many do you think there were in all of Europe?
I'm shocked to learn the estimates are only 30,000 people! Hardly even a small town... and spread over so much space. Humans were rare animals. Our shift to numerous is more extreme than I think we realize.
It explains why technology changed so slowly. Not enough people!
