Since 2008, Big Think has been sharing big ideas from creative and curious minds. The Think Again podcast takes us out of our comfort zone, surprising our guests and Jason Gots, your host, with unexpected conversation starters from Big Think’s interview archives.

Yuval Noah Harari holds a PhD in History from the University of Oxford and now lectures at the Hebrew University of Jerusalem, specializing in World History. His 2014 New York Times bestselling book Sapiens: A Brief History of Humankind, is published in nearly 40 languages worldwide. His new book Homo Deus: A Brief History of Tomorrow, uses historical and current trends to look at where we might we headed as a species.

In this conversation, Harari and Jason discuss giving credit where it's due to genuine signs of human progress, and the dizzying ethical questions that surround what's coming next –– from superhuman cyborgs to algorithms that know us better than we know ourselves.

Surprise conversation starter interview clips:

Lawrence Levy on Pixar, mindfulness, and the Middle Way. Daniel Dennett on the evolution of cultural memes.
