As I often note when this comes up, I've never actually written a Rails app. I've been writing Ruby for about five years now. A huge chunk of the devops world is written in Ruby (probably about the same in Go, much less in Python). It's still the "Perl of the future" and you'll find it all over the place. Rails is still big, especially in America--but there's a lot of other very influential stuff to it. If you're doing web there are other (I would say better, unless you're making Basecamp) libraries that do very well, too. Hanami is cool, Grape is good, and I'm in the process of building a Rack framework called `Modern` that's intended to be a turn-key, OpenAPI3-compatible framework to make the creation of API clients on the other hand a trivial experience.
