TIOBE is garbage but I would not dispute that Scala use is higher today. However, Scala and Clojure use both continue to rise. Well-written Scala and Clojure can provide comparable (ie Java level) performance. Clojure has tools (like core.typed and Prismatic's schema library) to optionally provide you with static typing where you want it, without the burden where you don't need it. Clojure does regular releases every year (that continue to be high quality and maintain backwards compatibility) and now has paid developers and support that will continue to accelerate progress. Because of the flexibility of the language, a great deal can be done outside the language in libraries (such as the entirely new concurrency paradigm in core.async).
