I get you want to compare with Go, let have some benchmark. Despite V being new, the difference is quite insignificant for short-lived process in most case. You are more likely use Go for production at this time.
And, its not necessarily an "either or" or "us versus them" situation, people can use both or whatever else "floats their boat". It's a bit disheartening to see programmers that fall into being so closed-minded or disparaging to other options or something new.
