Clojure's first stable release was in 2009 so it's either very young or very old, depending on how far you zoom out. Rust is exciting for use-cases that are very different from Clojure's, and the only thing I can say for Swift in this context is that I prefer it to Javascript, which I in turn prefer to other C-style languages. I'm currently working on a single-person (but expected to grow) project in Clojure and really appreciate the concurrency and state primitives, the functional standard library, the ecosystem and community of high-quality standard tools and packages, and (while I seldom write them myself) macros, which enable you to you write amazingly readable code. The community has a strong preference to functions over macros, but used judiciously you can get things like Clojure's core.async. So you get the benefits of a Lisp without a lot of the drawbacks commonly pointed out regarding other Lisps. I enjoy it a lot.
