The fact extensions in other editors are written in Java or TypeScript do not make it any easier to write them.
In any case, learning Lisp is useful, even if you never write an Emacs plugin.

Emacs is held back by not being easy enough to extend, because it uses Emacs Lisp? I don't see how. I'd expect learning to write plugins for some application to be harder than figuring out enough syntax/semantics of a language to call library functions.
