I always thought of Go as a middle ground between C and Python. From C it gets simple syntax, from Python - "batteries included" part.
Deserializing JSON and XML is a breeze from my experience. And it's available out of the box. But I guess C++ will get there with reflection having been approved in C++26.
So I don't think it will go away (in the coming years at least), since a lot of tools is written in it.
It's not that bad to handle some JSON in C++ or Rust. It can get annoying if you're doing it everywhere, but that's usually that's the kind of use case where JS or Python works anyway. Yes I get that some people prefer Go, but it's not necessary enough to guarantee that it'll stick around.
