WHO THE HELL ARE WE? is a series of short books and videos describing the evolution of civilization.
Almost everyone on the planet is five times wealthier than their ancestors only 50 years ago. This astonishing phenomenon has also improved health, education, and longevity. The cause; an explosive growth in ideas and productivity.
It began when we learned to control fire, evolved articulate speech and stumbled onto the way to create infinite wealth; free trade. The discovery of agriculture made us richer but we also learned how to destroy wealth. Great civilization grew up but then disappeared leaving only incredible ruins and ideas.
Later books detail some of the ideas and developments that increased the average life span from about 40 years to more than 80 and the average world income from less than $3 to more than $33 per person per day (and to $140 per day in some countries).
