I get you. Emacs is one software that you must invest some time to get the famous ROI. The promise is one unified interface for all the tools you may need (editor, tasks runner, shell, spellchecking, file manager,...). But the learning curve is there, although not as steep as some would make it appear.

One of my major motivation for putting in the time is that Emacs is very stable. You can coast for decades on a configuration. I don't mind learning new stuff, but it's grating to for it to be taken away, especially if there's no recourse (proprietary software).

Well, that's ironic. I actually do spend all day, every work day, in a piece of software which unifies most of the tools I need - editor, file manager, make console, find/grep frontend, etc. It's as stable as can be, since I'm the only person who maintains or even uses it, and it's as simple as can be, since I don't bother to write features in unless I really want them.

I've always supposed that emacs was for people with inscrutably complex text-editing needs, far beyond the bounds of my "nano is plenty" imagination, but if my cozy little coding environment is the kind of thing people are doing with emacs, I can understand why they would like that.
