Simplicity in design is still a panacea, only good programmers can do it on non trivial systems. Go will allow for better clarity, but beautiful code will not write itself.

Low cognitive overhead is also good for your future self, that will have to maintain the 'clever' mess which you wrote in a hurry ... In my experience so far, the abstractions that Go offers for writing concurrent code are very nice and easy to understand, and deploying it is really good - it generates static binaries, which you simply upload where you need them. It is a very practical language.
