David Smith, The Guardian:

A gathering of Silicon Valley alumni and whistleblowers and Washington lobbyists in the US capital heard warnings of potential links between tech addiction and sleep disruption, poor academic performance, anxiety, depression, obesity, social isolation and suicide.

Conference organiser James Steyer, chief executive and founder of Common Sense Media, a not-for-profit promoting safe technology and media for children, criticised giants such as Facebook, Google and Twitter. He said: “Talk is cheap. Show me the money. Period.”

There were pleas for Mark Zuckerberg, the Facebook co-founder and chief executive, and Sheryl Sandberg, the company’s chief operating officer, to apply values they advocate for their own families. Steyer added: “Mark and Sheryl at Facebook are good people. They are parents too. They have to think about their own kids when making a big picture decision there.”
