Blade Runner is a tech noir science fiction film directed by Ridley Scott, and starring Harrison Ford, Rutger Hauer, Sean Young, and Edward James Olmos, based on the 1968 novel Do Androids Dream of Electric Sheep? by Philip K. Dick.
For a city in 2019, which isn't that far from now, I used the model of Western cities like New York or Chicago that were laid out after the invention of mass transit and automobiles, with grids and linear transport. I thought, we're at 2,500 feet now, let's boost it to 3,000 feet, and then pretend the city has an upper city and lower city. The street level becomes the basement, and decent people just don't want to go there. In my mind, all the tall buildings have a sky lobby, and nobody goes below the 30th floor, and that's the way life would be organized.
