The cover story of the April 3, 1988 Los Angeles Times Magazine predicts the L.A. of the year 2013, with illustrations by Syd Mead, and prognostications about fiber optic computer networks, smart cars, and domestic robots who talk like Slim Pickens. A quarter century later, a USC engineering professor looks at what came to pass, what didn't, and what still might be in the near future. (Hopefully not Pickens-Bot.)
