"You want an accounting, not a whodunnit but a what-got-dun? Blade Runner got the computerized parking meters right, and the talking streetlights. (“Cross now … cross now … don’t walk … don’t walk.”) Robot Metrokabs? So close. Streetside newsstands carrying an array of glossy magazines? Yeah, about that. Face-recognizing polygraphs? Check your phone’s forward-facing camera. We enhance digital photographs, and we have voice-controlled gadgets in our kitchens. Billionaires promise a life off-world of excitement and adventure, but we don’t even have billboard dirigibles, much less reliable rockets."
