tl;dr - What does one call the genre space occupied by the 70s-80s tech of the Dharma Initiative (Lost) / Massive Dynamic (Fringe) / Hawkins National Laboratory (Stranger Things)?
When looking for inspiration for fiction set in a particular alternative-timeline it is often useful to read/watch other works from the same genre; but that is particularly difficult to do when one doesn't even know the name of that genre.
The latest blast of nostalgia in television sci-fi fantasy seems to be a lot of call-backs to the trippy science of the 70s and 80s. One of the first such examples might be the commune of Dharma Initiative scientists from the television series Lost. Not long thereafter, the crazy scientific exploits of Walter Bishop and William Bell in television's Fringe series further builds upon similar concepts. And now, perhaps most famously, Netflix's 80s-era series Stranger Things.
The genre can definitely lean into (slightly-better-than) Apollo-era computers and lasers, but the defining characteristic would probably be the more off-the-wall experiments tapping into some strange natural phenomena (and often accompanied by mind-altering drugs of some kind or another). Think LSD, isolation tanks, mind control, psychic powers, supernatural phenomena, ancient aliens, etc. Looking at a list of Cyberpunk derivatives, the genre clearly dates itself after the retro-futuristic aesthetics of Steampunk or Dieselpunk, after something like the Fallout game series' retro-futuristic atompunk/atomicpunk atmosphere or even the The Venture Brothers 60s-vibes late atompunk, but it's also clearly too early to be Nowpunk, Raypunk, or Cyberpunk.
So, is there any widely used name for this dated-tech-period genre that conveys the aesthetic of Carl Sagan and the AppleIII, or conveys the fringey practically-pseudo-science of MKUltra and similar covert military projects?
