“The simplest and most radical thing that Ridley Scott did with Blade Runner was to put urban archeology in the frame. I(t) hadn’t been obvious to mainstream American science fiction that cities are like compost heaps — just layers and layers of stuff. In cities, the past and the present and the future can all be totally adjacent. In Europe, that’s just life — it’s not science fiction, it’s not fantasy. But in American science fiction, the city in the future was always brand-new, every square inch of it.”
— William Gibson, on Blade Runner
