Daphne Koller of Coursera talks with EconTalk host Russ Roberts about online educational website Coursera and the future of education both online and via bricks-and-mortar. Koller, co-founder of Coursera with Andrew Ng, explains how Coursera partners with universities, how they try to create community and interaction, and the likely impact of widespread digital education on universities and those who want to learn. The conversation includes a discussion of why Koller left a chaired position in computer science at Stanford University to run a for-profit start-up in a crowded field.
