Charles C. Mann is the author of three of my favorite history books: 1491. 1493, and The Wizard and the Prophet. 

We discuss:

* why Native American civilizations collapsed and why they failed to make more technological progress

* why he disagrees with Will MacAskill about longtermism

* why there aren’t any successful slave revolts

* how geoengineering can help us solve climate change

* why Bitcoin is like the Chinese Silver Trade

* and much much more!
