What does it mean to see a rather promising Lisp-like language not getting traction, for the the future of Lisp(s)?
I think this sentiment ("Clojure is dying") has kind of become a Hacker News meme at this point.
Clojure basically came out of nowhere and pretty much displaced all other Lisps in about a decade. It is definitely not dying, it's just an opinionated, fairly niche language - it's not Go or TypeScript. It solves certain problems well and has some uses where it really shines. It's not a silver bullet, though, and it definitely requires serious learning/unlearning to get really good at it if all you know is the mainstream imperative/OOP style.
Clojure works well for those who buy its rationale: https://clojure.org/about/rationale
