I remember reading Popular Mechanics mags in the late 60s that told us by 2000, we would have colonies on the moon and maybe Mars, underwater cities, flying cars, and whole meals that could be taken in pill form. Lots of other neat shit, too. None of it has happened, and probably won’t.
Some of it has happened, but we either don't notice, or don't quite use the things the way the 1950's authors envisaged that we would.
I have hand-held access to pretty much the entirety of human knowledge, and am currently using it to discuss seventy year old sci-fi, as a short intermission from tirades against a literally insane former US President, who is running for the office a second time.
My Kindle would have fitted in very well, if it only had interchangeable tapes, with which I could load into it one book at a time.
We have permanently crewed space stations, but our radio and TV relays don't go via them, and our astronauts don't act as microgravity telephone exchange operators and maintenance crews.
We have computers with over a megabyte of storage, but rather than housing them in big buildings in secure defense facilities, we wear them on our wrists.
Much of the technology they predicted to advance rapidly - such as manned spaceflight - has stagnated; While the little stuff they didn't pay particular attention to - such as materials, batteries and communications - have in some cases advanced beyond their wildest dreams. And stuff they took for granted as ubiquitous and enduring symbols of high-tech have become laughable oddities - such as sliderules.
Some stuff has gone backwards. Golden Age Sci-Fi correctly depicted supersonic intercontinental flight as a part of the future; But never anticipated that by the C21st it would be history, except in those stories where the world succumbed to an apocalyptic doom that took out all technology more advanced than a pencil.
