Yuval Noah Harari offers his 21 lessons for the 21st century. In a wide ranging discussion with Andrew Marr, Harari looks back to his best-selling history of the world, Sapiens, and forward to a possible post-human future.

Technological disruption, ecological cataclysms, fake news and threats of terrorism make the 21st century a frightening prospect. Harari argues against sheltering in nostalgic political fantasies. He calls for a clear-sighted view of the unprecedented challenges that lie ahead.
