The way to become good at something is to do it for a long time and to be willing to think about what you are doing and continually improve.
There's much more to learning a language properly than just learning the language spec itself. Especially if we're talking about languages such as Java, where you have to know quite a bit about how the runtime works in order to be able to make good design decisions. And Go isn't really that simple either when we start to get into the weeds of performant concurrent systems that also need to be robust. It requires quite a bit of work to be able to make full use of what Go offers. It may look simple, but concurrency never is.
You're essentially arguing in favor of not being good at what you do, or at best being mediocre at lots of things. And I'm sure there are lots of jobs where that is okay. The thing is: why would you want to spend a lifetime being mediocre, to work on mediocre projects with other people who are mediocre?
