Uber founder Travis Kalanick just resigned as CEO after a controversial run, but he leaves behind a very powerful company — one worth an estimated $70 billion. Silicon Valley leaders like Kalanick have unprecedented power. Uber, Amazon, Apple, Facebook and Google have huge bank accounts and tremendous influence, culturally and politically. Where does that leave the rest of us, who are dependent on their tech and how it drives the economy? Is it time for people to push back against these multi-billion dollar companies? Joining Joshua Johnson to discuss the power of big tech companies is Cecilia Kang, technology reporter for The New York Times, Jonathan Taplin, director emeritus at University of Southern California's Annenberg Innovation Lab, Jeffrey Eisenach, director of the Center for Internet, Communications and Technology Policy at American Enterprise Institute and Jeffrey Rayport, senior lecturer at Harvard Business School.
