This feels apt in more than just science/technology. It matches my experience with culture as well, e.g. music and movies.
I knew I was officially old when I had to start trying to decipher what a teen was saying to me. All of the words were spoken in the language I speak, all of the words were heard by me, but their use of those words were not a use I was familiar.
I feel like many younger people still listen to music from the 70s, 80s, 90s, 2000s etc, as an exception (?)
It's way more apt with culture than with science or technology.
The lack of patience from adults for learning the byzantine interfaces companies were making in the last quarter of the 20th century got generalized to a ridiculous degree.
