Go is designed to be a niche language. A very big niche, but essentially still a niche: service components in clouds, where computing efficiency financially trumps development times. Go is more productive than C++, but less so than Python or some other alternatives. Go's tooling, linking and libraries make it useful in the Cloud, less so on mobile or personal computers. And the lack of third party libraries, combined with a relatively slower speed of developing these libraries (again compared to Python, javascript and others) means that Go will have a hard time going beyond cloud services.
