not only that, but the two main editors people fight over, emacs and vi/vim, have existed for that entire time, (though these days iirc microsoft's visual studio/visual studio code is more popular than either of them).
but they both retain a devoted following. emacs is known for being *very* customizable, and vim is known for being lightweight, available on basically any unix system, and having a unique control scheme that allows very fast text manipulation.
both are community-driven projects as opposed to the corporate-driven development of most other major editors, both are still in active development, both will probably last another 15 years easy.
