Go wins over Ruby and Python for many people due to it's speed, tooling, and trivial deployment. A language is more than just expressive power.

I personally don't find Go to be that interesting, but the number of Ruby and Python people who are making re move and are happy with it indicates that I'm an oddball.

What I think is that many moving to Go, do so without trying out other runtimes/compilers available for the said languages.
