The so-called “Big Tech” industry has dramatically improved our daily lives, but at what cost? Few people have gotten a closer look at these companies than Kara Swisher, writer for The New York Times and podcast host—and she says we need to wrestle more with that question.

Recently she shared her expertise with University of Chicago students as a fellow at the Institute of Politics. She taught a seminar called “The Five Horsemen of the Techpocalypse,” which examined Microsoft, Apple, Amazon, Google and Facebook. She recently joined the Big Brains podcast to give us her impressions of that experience, and to discuss the future of “Big Tech.”
