Isn't this supposed to be VIM vs Emac? What's is there point to be programming in the terminal anyway? Nano is good to fix some config files while your are in there, but if I needed to do real programming I'll be finding something that works in the GUI.
Oh it's about speed. What's the one that get your brain to be faster at programming? I use 4 fingers typing and am still typing much faster than I can think.
Definitely worth running through vim tutor at least once.
It's beyond typing speed, things like piping out strings to utilities is using one program to write another, you aren't just getting faster because of access, it's a paradigm shift.
Edit just for fun: im a non Dev dummy who happened to grow up in a Unix household. Even having dropped vim for helix and bounced around the MS admin/Apple IT space for 30+ years. When I switched to Linux I could still remember binds I'd set up and last used at 9.
It's speed, but it's also flow and a continuous stream of thought. If all your editing is being done with muscle memory and minimal thought, you can continue thinking about the problem at hand rather than interrupting your thoughts process to fumble through some context menu to make a change.
