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!
