I think you are omitting the main reason why Clojure never succeeded: it's dynamically typed at the core.

It's on the wrong side of history in that respect.

I know it's trying very hard to catch up to statically typed languages now by retrofitting some type system, but it's too little, too late.

Static types are where the current state of the art is, and we're not going back. Clojure missed that train and will never catch it now.
