When I did a comparison:

Crystal has 1,209 repos https://github.com/topics/crystal

Ruby has 19,721 https://github.com/topics/ruby

For those who needs performance for specific tasks, the option is easy since it’s a small investment to learn Crystal but Elixir is mature.

If we are targeting DevOp, other languages has several advantage like Go for microservices and could be work within mobile app.
