Sorry, but I have to be honest:
in my opinion most of the replies you got to this comment are extremely misleading.
As a user of Go and Ruby I can tell you that: Ruby is an awesome language, and there's nothing else that beats it at getting things done quickly and painlessly (unless you have a mathematical mindset, in which case nothing gets shorter and more elegant (at least the day you write it) than functional programming). It has many other defects, like safety in larger codebases, speed, some weird quirks, etc., but it's an awesome language, don't expect many other languages to be less painful than Ruby (on small programs at least).
Don't listen to those that say professional programmers won't use Go. The only reason a professional programmer will say hard no to Go is for extremely optimized or mission critical code that can't tolerate garbage collection (even though the GC in Go is very low latency) or need a more sophisticated type system, or numerical applications for which Go isn't really well suited.
If you compare Ruby and Python to Go, the transition might be hard if you haven't studied computer science formally. That said, it's a matter of making the switch, understanding that all those objects (boxes to put data in) that you had in Ruby, now are statically typed; this means that a box is of exactly one type and can't change midway (and even subtle changes need explicit casting/conversion). You also need to learn the difference between composition and inheritance, which might be tricky depending on how you learned to program... but beyond that, Go is a very small and easy-to-write-code-in language. You might like the syntax more or less, but it's easy to write good code in Go. It has many other gotchas and hoops you will need to jump through (var initialization, error handling, new vs make, weird append/len, learn to printf, learn pointers, etc), but it's a good step after Ruby / Python, if you need things bigger than what Ruby / Python allow you to comfortably manage.
A hello world might require defining a package, importing another package, and a more verbose print statement than python / ruby, but those are all great (and minimal) appliances when developing at a larger scale.
