It’s January, 1984. Steve Jobs, nattily attired in a double-breasted suit, is demonstrating Apple’s breakthrough personal computer, Macintosh, before a packed room. He speaks alarmingly of a future controlled by IBM, and shows a dystopian commercial based on that theme. He says that the Mac is “insanely great” and plucks the diminutive machine from a bag; it talks for itself. Screens of a graphical user interface — something few people had seen at the time — swoop by. The theme from Chariots of Fire swells. Jobs beams, as only he could.
