Have you tried looking for some ruby work?
Ruby is still a great, powerful language, but in the last couple of years I've started to notice that it isn't getting the tooling love that it used to from the community. I'd still work in it for the right job, just like most any other language. Because tools are tools.
Language shouldn't get as much emphasis as it does.
Note: Ruby is the programming language, but in the SaaS world that's usually coupled with Rails (the MVC architecture) and ActiveRecord (the database/SQL layer).
I didn't look properly or is Go's math scene not that great?
Possible - Absolutely.
