Ruby or Crystal?

Well ideally you wanna stay as far away from Ruby as possible, so in your limited choice scenario the answer is Crystal. If you go out of this limitation, use literally anything else.

Neither has a future, so Go

Go

It really depends on what you're doing. If you need performance and don't mind the lack of 3rd party libraries, Crystal is not bad. It's fast, uses green threads like Go, and the syntax is very slick. Ruby has nearly the same syntax, and a library for everything, so if you're doing a small project it'll be much easier. I wouldn't consider Crystal for anything in production until they stabilize the compiler and language features.

Ruby is fine if you are not going down the micro-services meme path, or don't need to scale to 100M users.
