Futuristic city, off-world colonies, flying cars, spaceships, androids, space monsters and .... non-flat TVs and monitors
If Scott directed
Alien and
Blade Runner today this things would have been changed for sure. It wasn't intentional. You cannot predict everything and you work with tools that are available at certain period of time. Who would have predicted flat screens?
Nonetheless I like juxtaposing in movies and books (love steam punk). That's why
Dune is probably one of my favourite books.
