Humane Wants Its New Ai Pin to Liberate You From Your Phone Screen

Ken Kocienda walks toward me, with a small white square pinned to his shirt. "Play songs written by Prince, but not performed by Prince," he says. The Sinéad O'Connor version of'Nothing Compares 2 U'--a song originally written by Prince--begins to play. A green volume meter, pause button, and next-song button appear on his hand. He twists his wrist clockwise, and the volume rises. Anticlockwise, and the song gets quieter.
