> The problems only start once the "tribe" grows beyond 150. That's when the number of people involved is too great for the human brain to process the entire social network. Hence why formal organisations and hierarchy are now needed. That's an interesting claim! Can we find any places where it doesn't hold up? Yep! In fact, there's a great book called Reinventing Organizations[1] where the author studied successful workplaces that have >100 people each. It's still a research project how to make these organizations work well, but the author and the community around that book are trying to gather working techniques because the benefits can be phenomenal (and that's empirical!)
