The Cambridge Analytica scandal in March revealed how a private company had been using Facebook newsfeeds to spread misinformation, manipulate emotions and advantage one political candidate over another—and a highly controversial candidate at that. It was a wake-up call for two reasons. “Algorithm” used to be a word you’d associate with computer scientists or mathematicians like me.

Facebook wasn’t the only tech giant to be panned this year for failing to think through the implications of its inventions. Back in 2016, Amazon started selling Rekognition, a facial recognition tool, to police forces.
