I worked in a large company where clojure was used. After the original developers moved on from that project (they always move on), it was a giant struggle to get people who could work in the code base. They ended up rewriting it in something more standard. Whatever benifit clojure provided was outweighed by the high cost of maintaining the code base and the inability to find devs who wanted to work on it.
That’s my only data point with clojure.
