Turns out also that, from an organizational perspective, it can take a lot to support n+1 programming languages. A codebase with 10 languages is more difficult to maintain than one with 2 or 3. As a result I think there is large benefit to having a language like Go -- it satisfies many overlapping needs, and organizations can avoid adopting too many other languages that fulfill niche areas. At Google there are only (5) core / officially supported languages: Python, Javascript, Java, C++, and Go. Python is generally applied in a scripting context. Javascript in frontend context. Java / C++ where you'd expect. Go for writing servers, application infra, tools, scripts, etc.
