Go doesn’t attract mediocrity it attracts pragmatism.
I worked on a Scala team for a couple years, had a lot of devs that were “smart”, problem was they wrote really fancy code no one could understand.
I then switched to a Go team and it was night and day. I was wildly more productive and the people in the community were not lacking intelligence.
Go prioritizes community, it believes that “us” is more impactful than “me”. This is its biggest strength, and is often lost on people looking in from the outside.
