Emacs lolz.
"GNU Emacs is an old-school C program emulating a 1980s Symbolics Lisp Machine emulating an old-fashioned Motif-style Xt toolkit emulating a 1970s text terminal emulating a 1960s teletype. Compiling Emacs is a challenge."

@cheesegrits til I learned that I am old enough to have seen some shit
@aparrish yeah, I felt kind of old when I realized I've used all of that tech, starting with actual honest to ghod Teletype 33's, although we didn't have Emacs on those. And they were old tech when I was using them in the early 80's, to generate patches (literally) on paper tape for a military avionics testing rig. Along with a manual hole punch and mylar adhesive for patching the patches.
