American historian and New Yorker staff writer Jill Lepore talks with Recode's Kara Swisher about her new podcast, The Last Archive, which investigates "who killed truth?" in the style of a true-crime show. Lepore discusses why the protests against systemic police violence represent America "at our very best," but explains why the two main competing theories of American history are both wrong — and how it should be taught and studied instead. She also talks about the history of technologies, from photography to social media, that have been the subject of a political "fantasy" and previews her upcoming book about Simulmatics, "the Cambridge Analytica of the Cold War." Plus: What would Lepore do if she were a historian in the future trying to understand 2020?
