I see it in the sense of writing your game logic in Go using bindings for Unreal or one of the big ones. The real performance critical stuff will probably always be in C++. The popular game Rust (not language) uses Unity and the overall engine is pretty bad but it works and made them a fortune. By its nature it is incredibly extensible. You can mod it by dropping source files with hooks right into a directory without compiling anything. The ease of that kind of stuff draws people like crazy.
