"It's the economy, stupid", said a former US President. It's the economic attributes of a language that contribute to its market share. Go is a very good language from an economic point of view. (Java was also a remarkably good language, from an economic point of view.) As to the your specific point, I suggest a sufficiently large slice of software workers will include the sub-set that write long articles defending their theoretically so-so but economically superior languages: Those blog posts are a feature, not a bug, of economically viable programming languages. The bottom line is no one has proven that "the bottom line" is positively affected by use of sophisticated languages. The killer app of ho-hum languages is their demonstrated economic value.
