True, but I'm not talking about simple users. I'm talking about companies extending Kubernetes or building adjacent software. Even if their service doesn't necessarily integrate with Kubernetes, there is frequently a temptation to "follow your heroes".
Look at the whole Cloud Native Foundation thing, I think most of their projects are developed using Go.
So if you're using that stack, it's easy to assume that all new development everywhere is in Go.
It will probably balance out once the newness wears off Go (I think this is already happening).
