I'm going to date myself here but I remember a time when I was teenager, and the software functionality in the PC-era was advancing at such a rapid clip that it was next to impossible to keep up.
Windows would have tons of new features every year, browsers advanced, email clients advanced, photo-editing tools advanced, etc.
I don't know why my physician parents bought a computer but I'm really glad they did. I made sure I knew about every single feature / option across the hardware (I'd open it up and upgrade RAM, sound cards, etc.), operating system and apps.
That was a time when you could buy books to learn Lotus 123 or Photoshop or whatever. And the books were super useful but also stale by the time you finished reading them.
The mobile / Internet cycle for some reason felt slower to me.
The AI cycle feels similar although maybe faster. Back in the PC era, my ability to use the new thing came down to my having the time / budget to go upgrade my hardware / software.
Every time I log into Claude / Chat, there is a bunch of new stuff I haven't tried yet, new offerings weekly, etc.
And it's all immediately available for basically free.
This is a worthless comment but that "real functionality advancing far faster than adoption" was a 1995-1997 feeling, not a 2000 feeling.
And there will be a time when Office kills off Lotus 123, Windows NT kills off Novell NetWare, Access kills off Borland, Adobe kills off QuarkXPress, etc. But maybe that's a handful of years out?
