“Every once in a while, a revolutionary product comes along that changes everything,” Steve Jobs said in 2007, when he introduced the first iPhone. Eleven years later, the question isn’t whether he was right. It’s whether we like the way we’ve changed.

Today, the average American checks his or her phone 47 times a day — many more if they’re younger — and spends about four hours a day staring at its screen. That’s roughly a sixth of our total time alive. Given these numbers, it makes sense that there’s an increasing sense of concern over our relationships with our phones. In January, two of Apple’s biggest shareholders wrote an open letter to Apple requesting that the company provide “more choices and tools” that can help parents set limits on their children’s phone time. In the same month, Facebook announced that it had overhauled the algorithms behind its news feed, to put more emphasis on “meaningful interactions” — i.e., posts from friends and family members, rather than brands. And February saw the launch of the Center for Humane Technology, a coalition of former tech employees who are alarmed about the impact of the technologies they helped create.
