How are technology, artificial intelligence, robots and drones impacting our society and our economy? Brad DeLong says the disruptions and dislocations they prompt are nothing new. Think about Andrew Carnegie’s father in the 19th century being forced to abandon his Scottish handloom and move to America to work a telegraph operator — what was then the ‘high-tech’ sector. DeLong is a professor of economics at UC Berkeley. He spoke with media innovator Peter Leyden at Uncharted: The Berkeley Festival of Ideas in October 2015.
