Using gptel? Or something else?
Emacs was literally the sanest option unless you could bribe the sysadmin into installing "joe" or similar. ("pico" and "nano" came later).
The other thing is back in the day emacs was often a good option for running clients to connect to things like IRC or MUDs or MOOs, and even Gopher and the early web. It was also an excellent news and mail reader!
And so I used emacs as a general text editor and MOO and IRC client long before I ever used it for writing source code really (for which it was also obviously very good).
It's a holdover from the days when people used to type without looking at their keyboards or waste time and effort taking their fingers off the home row to find and stab around with some kind of multi-axis valuator device sitting on their desk somewhere.
I trained in touch typing in the 80s/early 90s in typing classes, on Selectric typewriters. Beautiful keyboards.
