I don't want to learn languages, I want to solve my problem.
The more languages you learn, the more problems become trivial. Well, if you're just doing imperative languages, you're not liable to learn much new stuff, but... learn O'Caml[1] and Haskell and you'll be all the richer (and more worried!) for it.
One particular aspect of Racket that is truly amazing is the modularized language support for macros. One would generally insert a caveat here, but I do think they are actually "best in breed" at the moment -- even going so far as: http://www.ccs.neu.edu/home/stchang/popl2017/
