And who else is in a similar field? 3% of all programmers? In that case, fine. But most people I see raving about Go can afford the performance hit any time (if there is any).

PS: Coding go is my day job.

The systems community is quite large, consisting of probably around 30-50% of the dev jobs in companies like microsoft, Google, Facebook, Apple.

Go was designed as a system's language, I think it just eventually went in a different direction when people realized it would never match C++ or even Java in performance.
