...in what sense has Clojure actually won over Scala?
I see way more Scala in companies last ~5y and have the impression of its ecosystem being more robust. Not uncommon for greenfields. It's longer than that I even encountered an active Clojure codebase. This is from a data-engineer perspective.
Clojure may be more popular for some niche of app startups perhaps? We are in different "bubbles" I suppose.
I can't really speak to modern stuff, and it is certainly possible my memory is faulty. Scala was a PITA in the early 2000s and you were generally better served with something else if you could move off the JVM. Clojure came in about mid 2000s and seemed to be what a bunch of people stuck on the JVM but doing data processing were desperate to find.
My feeling was that a lot of Clojure folks moved on as the data processing stuff moved on from Java/JVM.
My impression has been that JVM-based languages have effectively been on a steady general decline for a while now. Java has fixed a lot of its issues; Kotlin gave the Java expats somewhere to go. And Javascript/Node along with Go drained out the general masses who didn't really want to be on the JVM anyhow.
However, it is interesting that Clojure has effectively disappeared in those rankings.
