Emacs is often confused as being an editor, but it's not.

It certainly houses a few different editors, including Vim (as people will often point out eVil is Vim inside Emacs)

Emacs is basically a text centric computing platform, built with a flavor of Lisp.

At this point there's several thousand apps / packages.

It used to be a joke that Emacs is an Operating System that lacks a decent text editor. These days it has several.

The joke now should be that it lacks a decent logo and marketing department.

Or perhaps the joke should be that Vim users are terrified they're missing out on something they don't get so they use snark as a defense mechanism.
