Same here! Aside from the basic unix tools in /[usr]/bin/, there is very little software with the longevity of emacs. I fully switched from vi to emacs in 1992 and been using it heavily every day since then. So good.

(The only other program I can think of from that era that I still use is trn to read USENET)
