Or maybe you can just accept it as something other people might enjoy
even tho you don't ;-)

Yet, as a teacher, I very often am exactly in that situation, where
either the student or I write slowly on the board to try and express
visually what we want to say.  Now, "plain text" like we have in Emacs
buffers isn't quite the same, but now that I have to teach via
video-conferences, I regularly share my Emacs frame over Jitsi and they
watch me slowly type code (and erase and retype) while explaining out
loud what it is I'm doing.

It may sound slow and painful, but the low speed is actually useful to
give them time to understand, and the fact that it's done "live" makes
the feedback loop much more effective when it takes several back&forth
between the students and I before we come to an understanding.

And of course, all that applies as well sometimes when discussing
research ideas among peers.

Yes, we *also* do that (using Git, typically to share a TeX document or
source code) and that's where the meat of work takes place, but at times
the fast back&forth of "live editing" (or just talking) is very helpful.
