An analogy to pique your curiosity: I would say that if Java was a balloon, Scala would be a zeppelin, and Clojure would be a plane.
I would also say that the stewardship of Clojure is much saner than that of Scala, due to a strong emphasis on stability. Typesafe / Lightbend is bigger than Cognitect, but big does not mean reliable. One sign of this is that Clojure now grows via libraries, the core having reached stability. Scala is still figuring out its fundamental semantics.
