Recode Decode: Noam Cohen, author, 'The Know-It-Alls'

Author and former New York Times columnist Noam Cohen talks with Recode's Kara Swisher about his new book, "The Know-It-Alls: The Rise of Silicon Valley as a Political Powerhouse and Social Wrecking Ball." In the book, Cohen argues that a libertarian philosophy that is hostile to outsiders and resistant to regulation is negatively affecting our society and communities. He diagnoses the problems with Google, Facebook and Twitter, noting that the latter has a business incentive to do nothing about hate speech and bots. However, Cohen says he's hopeful that Congress and regular people are "waking up" to the dangers of letting Silicon Valley run the world.
