I think there are different levels of "learning" or "knowing" a language. I can write some code in almost any language within a few hours but it will basically be C/C++/C# code with a different syntax. This level works for a lot of purposes. But really understanding a language and its ecosystem can take many years (with C++ several lifetimes. I wonder if anybody really understands C++). I used to be really excited about learning new languages but nowadays I try to keep it small, focus on a few and get really good at them. Constantly switching languages feels shallow.
