Yuval Noah Harari (Sapiens, Unstoppable Us) is a historian, philosopher and best-selling author. Yuval joins the Armchair Expert to discuss how people create fantasies in their minds about the real world, why he wanted to write a children's book, and how humans are capable of building large collaborative communities. Yuval and Dax talk about how the invention of fire advanced human civilizations, how humans evolved to the top of the food chain, and why people lose their faith in the systems that run their lives. Yuval explains why he doesn't like to hear his own voice, what the concept of social scores based on technology tracking is, and how the stories of religion can change over time.
