The man who made computers personal was a genius and a jerk. A new documentary wonders whether his legacy can accommodate both realities.
An iPhone is a machine much like any other: motherboard, modem, microphone, microchip, battery, wires of gold and silver and copper twisting and snaking, the whole assembly arranged under a piece of glass whose surface—coated with an oxide of indium and tin to make it electrically conductive—sparks to life at the touch of a warm-blooded finger. But an iPhone, too, is much more than a machine. The neat ecosystem that hums under its heat-activated glass holds grocery lists and photos and games and jokes and news and books and music and secrets and the voices of loved ones and, quite possibly, every text you’ve ever exchanged with your best friend. Thought, memory, empathy, the stuff we sometimes shorthand as “the soul”: There it all is, zapping through metal whose curves and coils were designed to be held in a human hand.
