> strange to me how nobody questions why beavers only make damns a certain size, birds only make nests and don't go beyond that in complexity.

Probably because beavers and birds have made dams and nests the same way for the past 100 years, whereas humans in the same time have developed a bunch of tools and can specialize and distribute the fruits of their expertise without requiring others to be experts themselves.

Perhaps it's not true that on average we know more e.g. math now than we did 100 years ago, because there are so many more people. I believe we are nonetheless much better at teaching and learning now.

It's more than possible that all of this growth will be our downfall, and that that will regulate our growth, however.
