As elegant as lisp is, I think the flexibility just kills its usability on teams, while more rigid languages like Java, Go or C see massive adoption. Language expressiveness is rarely a real bottleneck, compared to debugging and understanding program flow and getting new contributors up to speed.

Separately I think each lisp has an individual fundamental flaw that makes it unusable for production, eg clojure having terrible error handling, common lisp being case insensitive, scheme having a minimal standard library, racket being fairly slow, etc.
