Those mid 80s high temperature superconductors are now mass produced for NMRs and fusion startups.
I don't think it's given that all superconductor breakthroughs will require 40 years to get to that point and there's good reason to believe they won't (startup penalty, industry bootstrapping, market finding, etc. have all been completed).

As alluded to those same pop science magazines promised a fusion future too. Here we are, magazines extinct, with fusion startups using LN2 superconductors. Also: no quantum computers, no space colonies, no flying cars (or even supersonic planes), and twitter/reddit/facebook are worse than Usenet.

I get it ...
But how many of them predicted their use in ~36,000 advanced medical imagery devices world-wide?
I'd love fusion power (and flying cars), too, but there's a whole lot of interesting technology between "check out my shiny new super-conductor" and "let's use it to contain plasma that's hotter-than-the-core-of-the-sun-kind-of-hot[0]" that we do benefit from[1], today, to not be too disappointed that we haven't quite reached the greatest potentials.
I don't know enough to speak intelligently on any of this -- who knows -- maybe fusion won't be a possibility until even higher-temperature super-conductors are created ... or maybe there's some other "not possible" in the way (until another discovery is made).
[0] And (if I understand things correctly) it's probably really unfortunate that they traditionally require extreme cooling, likely made more complex given the heat involved and almost certainly requiring far more power than would be required if said super-conductors worked at much higher temperatures.
[1] Myself, personally -- and I have a pretty cool 3D file of my brain backed up to my server as a result.

Absolutely right. People generally understand that "collective human knowledge[0]" grows but they think of it as a linear system. The speed at which knowledge grows accelerates -- not at an even pace -- but I'd wager somewhere near exponentially in a lot of places.
And each discovery can change our understanding of other things/accelerate discovery in other areas.
