That is the novelty:) Don't worry; we'll tire of Go in 1-50 years;)

It’s so that we, hackers, can see if it’s worth looking at the source. Personally I look at the source of Go or Rust projects because I’m not top proficient in the languages and it’s a way I can learn idioms.

In fact, since this is for a developer audience, I’d wonder why you wouldn’t say what language something is in.

I don’t think your question has any sense in a forum with the word “Hacker” in the title.

Once we've rewritten everything in go. More realistically, once the language is stable and known enough that these things become uninteresting.

Could you elaborate? I don't understand what you are implying

When you cannot do X in language Y stops being an issue.
