Watch Out Workers, Algorithms Are Coming to Replace You — Maybe

Over the past five years, the Israeli author and historian Yuval Noah Harari has quietly emerged as a bona fide pop-intellectual. His 2014 book "Sapiens: A Brief History of Humankind" is a sprawling account of human history from the Stone Age to the 21st century; Ridley Scott, who directed "Alien," is co-leading its screen adaptation. Mr. Harari’s latest book, "21 Lessons for the 21st Century," is an equally ambitious look at key issues shaping contemporary global conversations — from immigration to nationalism, climate change to artificial intelligence. Mr. Harari recently spoke about the benefits and dangers of A.I. and its potential to upend the ways we live, learn and work. The conversation has been edited and condensed.
