Kevin Bankston wrote for Slate's Future Tense on building science fiction worlds, specifically referencing the world build for the movie Blade Runner 2049 (no spoilers!).
Blade Runner is often cited as one of the best, most visually inventive science fiction films ever. With the possible exceptions of 2001: A Space Odyssey and Minority Report, no other film has created a fictional future world so detailed in its execution, so comprehensive in the scope of its vision, and so accurately predictive of—and influential on—the design of the real world. But these movies aren’t just another illustration of the powerful feedback loop between science fiction and reality. If we look closer at the world-building techniques underlying these movies’ possible futures, they may even help us redesign our own futures for the better.
