Great to see my favorite language evolving! I also use various lisps, Java, Haskell, Typescript, JavaScript, Python, etc., but I am happiest when coding in Ruby.
Unfortunately, most of what I do now is machine learning, and Python wrappers for underlying C++ code have by far more support than Ruby. (Ruby does have some great ML projects and libraries though).
I'm on a similar boat, and am eagerly awaiting production-ready releases (and wider adoption) of both Crystal[1] and Julia[2] languages. Crystal for the Ruby-ish syntax, and Julia because it seems to be shaping up into a language I like even more than Ruby.
