It already did, with Puppet, Chef and Vagrant.

Also, mruby is gaining adoption and Rubymotion seems to be in an interesting niche.

There's a lot of new projects currently (like Lotus), so I wouldn't as negative as this.

Also, don't ignore the foothold that Ruby has in the asian markets.

Puppet is only "escaping" in that it's implemented in Ruby. It's not people outside the Rails world picking up Ruby.

Chef, in my experience, is favored almost exclusively by people who are already Rubyists. The concept of applying The Power Of Ruby (TM) to system configuration is not attractive to non-Rubyists.

I don't see Vagrant much these days. I suspect Docker is displacing it.

The fact that Ruby is the language chosen to implement these tools is the proof it's not just for Rails.

Also, Docker may become more popular but I doubt it is going to replace Vagrant. There are just too many times where you need a full VM instead of a container process. Not every problem can be solved with containers.

Also where do you test your docker containers in?

Also, SketchUp. (http://www.sketchup.com/intl/en/developer/)
