It occurred to me some time ago that the big question is the opposite: What do we not do that humans thousands of years ago did with their brains?
My thoughts went like this:
Since the brain is quite expensive evolution would not have grown it so much if it had not been needed. But this means humans really used all that brain.
That means if we now use it for so many very different things in a very - very! - recent technological world, with an equally recent extreme increase in population density worldwide (both movement top cities as well as the unprecedented total population size increase), what exactly did they do?
I think that this indeed is a very interesting question, I'm not sure we can answer it. Medieval brains are one thing, but what about 20,000 years ago? The brain must already have been pretty much the same.

We now have to deal with a lot more people than any of our ancient ancestors, and a lot of change. Our networks of work and cooperation are unprecedented by anything in history too.
