Do people still use Clojure? For a while I was really hot on Clojure ... but then I haven't had a project in ten years where it even makes sense to introduce it into operations ... generally I've got Python or Go on the server and some mix of JS, Dart, Objective C, or Kotlin on the front end depending on the client platform.
Maybe someday I'll be responsible for writing a system back end from scratch and I can take off on a flight of fancy like this.
