I do. While I cannot speak for Clojure and Elixir, I can speak for Haskell, which I have moved to from Rails.
10x for me is:
1. A 70MB all-in binary to deploy, using 1-3MB of memory when running (has a build in HTTP(S) server), responding in 2-10ms to my requests. Compare that to 700-1500MB of gems, using hundreds of MB while running, serving requests in 50-200ms... More then 10x! And my framework of choice (Yesod) consists of 23kLOC, where Rails has 210kLOC (source: openhub.net)... Another 10x!
2. Less bugs when growing the codebase; "strong compile time guarantees" is now my main weapon when fighting maintenance curve.
Back in my Rails days I'd say "typing is a very narrow form of automated testing", which given my exposure to C++/Java was defendable opinion.
Now I say "strong typing is a wonderful test suite you get for free and automatically stays up to date". Not that it replaces tests; but it literally a wonder how Haskell's HM-typesystem it rejects broken code at compile time.
TL;DR: I believe 10x frameworks are out there.
