No. I don't see any benefit of using it over java or JVM languages like clojure/Scala which have huge ecosystem attached to them and now even clojure supports Go like concurrency too.
I've actually seen more Scala adoption than Go. In my experience Scala is getting used in production whereas Go is something people play around with from time to time.
Because there are multiple mature web frameworks for Scala, I think. Go has yet to produce one (Revel? I think is coming close). I think web frameworks help drive adoption. I see that happening with Haskell too (as web frameworks mature more people get into it through that).
Compare Go in early 2014 to Scala early 2006, that is when they were about the same age.
If it really is set to "take over the world" it will need to be growing subtantially faster than 2006's Scala.
One major obvious benefit Go has over Clojure or Scala is simplicity.
One major obvious benefit Clojure and Scala have over Go is having features developers need and want.
