Charles C. Mann is the author of my favorite history books, including 1491: New Revelations of America before Columbus. 1493: Uncovering the New World Columbus Created, and The Wizard and the Prophet: Two Remarkable Scientists and Their Dueling Visions to Shape Tomorrow's World. We discuss why Native American civilizations collapsed, why he disagrees with Will MacAskill about longtermism, why there aren’t any successful slave revolts, how Bitcoin is like the Chinese Silver Trade, & how geoengineering can help us solve climate change.
