From hacking to terrorism, and our polarized world, it’s going to take a radical rethinking of everything to survive this century, says historian and best-selling author Yuval Noah Harari.

Harari is a lecturer at the Hebrew University of Jerusalem, where he specializes in world history. He is the author of "21 Lessons for the 21st Century," "Sapiens: A Brief History of Humankind" and "Homo Deus: A Brief History of Tomorrow."
