Extensibility is the reason for Emacs&#x27; power. Lisp is just an implementation detail. You could make an equivalently powerful editor in any high-level language.<p>There are other extensible editors, but the line between Emacs&#x27; kernel and its extensions is drawn at a different place in Emacs than in any other popular editor. It is more likely that any given feature you&#x27;re interacting with in Emacs is provided by its extension code than it would be in another editor.<p>Probably more important is the benefit Emacs gets from being one of the two major Unix editor projects. It has an immense community and user base.
