So they try to make the least-worst JVM environment which is great if you're dead-set on using the JVM, which has a lot of pros.

For most people Python/Javascript also does the job and you don't need to learn another paradigm — a Lisp — to code for it, which also makes sense.

However, learning a Lisp also makes you a better coder because of immutability and less side-effects. Hence why Clojure is still around.
