I like most of PGs writing but being a smart and successful founder/investor doesn't automatically make you a proficient anthropologist. Arguing that you shouldn't work for large FAANG style companies because our early hominid ancestors hunted only in small groups is just comical.
If you're really interested in reading about human evolution I recommend reading Robin Dunbars' work, who's an actual anthropologist.
If you look at hunter gather societies, I don't see how PG's arguments are comical. They are by and large egalitarian and up until about 8k years ago almost all humans were part of small, egalitarian groups (i.e. hunter gatherer tribes), so our brains are evolved for that environment instead of being part of a multi-thousand people highly hierarchical organization https://en.wikipedia.org/wiki/Hunter-gatherer#Social_and_eco... .
I don’t know that it’s comical, nor was the article really about human evolution. And there are other studies and evidence not based on early hominids showing that there is an upper limit on effectiveness dependent on group size.
