I see the same trend in programming languages. Say a really solid career lasts from about 20 to 60, 40 years long. Say that halfway through your career, 20 years in, you're considered a respectable senior dev who gets to influence what languages companies hire for and build on.
So in 20 years in, the current batch of senior devs will be retiring, and the current noobies will have become senior devs.
*Whatever language is easy to learn today will be a big deal in 20 years*
That's how PHP, Python, and JavaScript won. Since JavaScript got so much money poured on it to make it fast, secure, easy, with a big ecosystem, I say JS (or at least TS) will still be a big deal in 20 years.
The latest batch of languages know this, and that's why there are no big minimal languages. Rust comes with a good package manager, unit tester, linter, self-updater, etc., because a language with friction for noobies will simply die off.
One might ask how we got stuck with the languages of script kiddies and custom animated mouse cursors for websites. There's no other way it could turn out, that's just how people learn languages.
