I would say the cultural and technological shifts between 55 and 85 were far bigger.
In 55 space travel was in its infancy, segregation still existed, jet planes were in their infancy, computers were in their infancy. The impact of consumer technology was really the family TV and the car.
In a lot of ways today is just a evolutionary version of 1985, whereas 1985 was mich more of a revolution from 1955.
I think the time is right for another sequel - jumping forward to 2045.
It also doesn't focus as much on television, except to the extent that people in 1955 apparently didn't know what a "rerun" was. (Did they in reality? Honestly don't know.) The other side to that is, back in 1985, if you wanted to see an old episode of I Love Lucy or Gunsmoke (which had actually gone off the air by then, I believe) you either caught the rerun of the one episode some network was broadcasting or you were SOL. I'm not sure anyone was even selling video tapes of episodes back then, even assuming you were one of the comparatively few people to have a VHS or Beta player. Your cultural library for recent-ish pop culture was about a millimeter deep, compared to now.
So, yes, 1985 is closer to 2015 than 1955 was to 1985 in some key ways. Some of that is because you can only repeal Jim Crow laws once. Some of that is because Netflix has Punky Brewster on demand. Some of that is because most people are neither gay nor trans.
Well, rights or no rights, they are still a quite small minority -- say 10% of the population for both. And that's the big number -- because the more relevant for a movie number, that of "trans people" + "gay people that you can tell from straight people" (e.g. with clear stylistic choices in clothes etc) is much much smaller.
So, unless the script calls for it, they'd only show one in a movie with like 5-10 people in the whole cast if they want to go out of their way to include the "token gay guy".
I believe they did not: teevee was broadcast live, and mostly not recorded. IIRC.
That might be part of it, but I think a lot of it is just that the Baby Boomers are the worst generation in history, while today's younger folks are…just younger folks.
Socially and culturally however I think they achieved many great things we take for granted (birth control access, environmentalism, civil rights advances, multiculturalism, the sexual revolution, etc).
Why do you think so?
PCs weren't really mainstream in 1985 (though C64s and the like were relatively common)
Hardly any consumer PC could connect to the pre-WWW Internet. And I'm not sure a lot connected to online services in general. (As I recall, a service like CIS had hefty per-minute charges at the time.)
So relatively few consumers had email or any way to get information online.
VCRs existed but I'm not sure how widespread they were; I know I didn't have one until the late 80s so there was relatively little timeshifting. Cable TV was fairly widespread though.
Few had mobile phones and air charges would have been significant. Answering machines were readily available but I don't know what the penetration was.
Anyway, my basic point is that the mainstream consumer would find the pre-eighties and the post-eighties to be enormously different world from a technology perspective, especially with respect to communications. I frequently think if I were to go back to my job in 1986, I'd throw up my hands in horror at my inability to do my work--given the difficulty of getting information and generally communicating (though we did have internal email).
A C64 was a PC (sensu latu) and the latest Dell/Compaq octo-core gaming rig is a PC, so same-same. Name hasn't changed, so the massive technical advance is hidden.
The BBS networks were networks and the Internet is a network, so they're the same. Never mind the fact BBS networks were lucky to get email across the country in a few days whereas Internet users can chat real-time with full voice and video around the world.
Cell phones existed in 1985. Cell phones exist now. Guess which devices can access global databases in a fraction of a second and which devices were bags which had handsets wired to them so people could make and receive phone calls from their cars!! Again, though, the name remains the same.
People in 1985 had cheap cameras. People in 2015 have... cell phones.
People in 1985 had little black books with phone numbers in them. People in 2015 have... cell phones.
People in 1985 had really nifty digital watches. People in 2015 have... cell phones.
(Really, though, the fact cell phones have kept the same name is pretty amazing, given how radically the devices themselves have changed.)
Now we think nothing of calling somewhere, as long as somewhere is "within civilization" - even if it's a materially poor, remote area. It's easy to find goods online, even relatively obscure ones. And if we have a question about a specialized field, we can usually find some online source that can point us in the right direction.
What we haven't really done yet is reorganize the economy to make good use of all these new efficiencies. We still manufacture and market as before, just using some additional channels.
...synced to really nifty digital watches.
But you just gave me a great product idea. Wifi accessible infra red remote controls that you'd mount in various rooms in the house that contain IR-remote controlled objects (TVs, ceiling fans, etc) along with an app to control them from your handheld.
Between 1955-1985 we had the civil rights movement, the moon landing, the Vietnam War, and the final decades of the Cold War. Between 1985-2015 we've had the fall of the Soviet Union and the Berlin Wall, the Gulf Wars and Afghanistan, and 9/11. I'm obviously missing some other significant events.
We also had technological shifts - 1955-1985 saw records -> tapes, but CDs and PCs were not quite massively adopted yet. 1985-2015 has seen CDs -> flash storage, mass adoption of PCs -> laptops -> smartphones, and social media apps. Much of the advances in technology have connected us geographically and temporally.
I feel like the significant events between 1955-1985 separated the youth of the 80's from the youth of the 50's, more than the significant events from 1985-2015 have. I also feel that many changes between 1985-2015 actually connected today's youth to people and events of the last 30 years.
