From Google's POV, Go is the future, not Python 3, they created it for this reason. As mainly a sysadmin these days, I tend to agree with them for their use-case. For deployment, performance and overhead, Go is great for system tools, which is reflected in the new toys in the "sysops" toolbox. Pretty much every-one of them is written in Go these days, where that used to be Python or for a brief period Ruby or C/C++ for the more performance sensitive stuff.
