In this episode we discuss why, after years of trying to make their products as addictive as possible, social-media companies are now heading in the opposite direction. We look forward to key dates later this year for elections, Chinese anniversaries and historic figures. And we ask what the former headmaster of Eton College is bringing to China’s educational system. Tom Standage hosts. Music by Chris Zabriskie "Candlepower" (CC x 4.0)
