AFAIK FFI and use of existing JS libs is a pain in both Elm and ReasonML (that is my subjective, empirical observation). Purescript is nice, but what would you use in the back-end? Haskell? Or would you target nodejs? Deploying and maintaining nodejs clusters is not fun. Using Haskell in the enterprise could be fun, but getting to the level where it is fun is extremely hard. Finding and hiring people is also difficult. Searching for a Haskell job is difficult.

People often dismiss Clojure for being dynamically typed, but it has Spec and Spec is awesome.

People dismiss Clojure because it's JVM based, but they missed the fact that JVM actually is pretty robust and very nice piece of tech.

People dismiss Clojure because "all the changes to the core have to be approved by Rich Hickey", but they miss the fact how stable Clojure is. It is hard to find a language ecosystem where you can pick any library written years ago, bump versions of major components and expect everything to work.

I am not even talking about how people ignore Clojure because it is a Lisp. That's just outright dumb.

There are no silver bullets. Any language ecosystem has its own limitations and incur certain degree of frustration. Clojure nicely minimizes frustration. It doesn't get rid of it completely (otherwise they wouldn't call it "work", they'd call it differently and I wouldn't get paid for it)
