I'm not a graybeard, I'm 28 and I've been using Emacs since I was 15. In that time, in my circle, I've seen notepad++, sublime, atom etc. all come and go. Of course everyone at work uses VS Code, in 2 years it will be New Editor by XYZ Corp.

Being old doesn't imply something is bad. Should we be asking what Emacs and Vim have done right so that they're still being used 50 years later?
