> Also, the human brain was never designed to handle social groups much larger than 100. The human brain has only approximately 7 registers, therefore all of humanity's accumulated knowledge and culture can't have come into existence because 7 registers per computational node is insufficient? These cognitive limitations are better understood as challenges, not fundamental barriers. Culture is an immensely powerful tool. Indeed, one might argue that culture is so powerful that as our capacity to construct and leverage culture grew the selective pressures and evolutionary need for further increasing other, primitive cognitive limits diminished.
