Zillions of people. Usually it gets called steampunk (18xx) or dieselpunk (193x-194x). 195x-6x futurism usually ends up going very Googie. And we’re starting to see 70s/80s retrofuturism, mostly I’d say the word associated with that is vaporwave.
More art than actual tech, and most of the tech is one-off hand-built stuff.
Vaporwave, despite using a lot of 80s samples, is generally more associated with the 90s. Vaporwave is all about the simultaneous apex and decline of mall culture, consumer excess in optimism of the post-Cold War, and early WWW aesthetic.
