Im considering spending some serious time learning one of the above. Two principle engineers I work with exclusively use them, and watching them work is incredible, the speed they move and get things done is pure wizadry. Can anyone learn this skill? For what it’s worth, the alternative is learning VScode. I’ve exclusive used Android Studio in my career.
Vi, yes, it’s on about every distro especially server one without X.
I used exclusively emacs last century, even in DOS/Windows, but not anymore, vi or nano are ok for simple editor.
