Learning new languages may be component of it, but I think more generally, different languages are suitable for different problems and different developers. Being free to use the most suitable or preferred tool for a task is undoubtedly desirable, rather than having JavaScript as the only option. And, while more of a personal opinion, JavaScript is not a well designed language - permanently shackling the web to it prevents progress forward.
