Social Media's Dark Side: How Facebook and Snapchat Try to Steal Our Self-Worth

'We've made it through every new technological wave—newspapers, radio, TV, laptops, cell phones—without the social decay that was widely prophesied, but there's something different about smartphones loaded with apps living in the palm of our hand, says tech ethicist Tristan Harris.
