It has nothing to do with intelligence. vi and emacs are just rote memorization and also endless installation of plugins and configuration. They are slow to pick up, but very powerful and also ergonomic once you know what to do. A modern GUI like CSCode is faster to pickup and immediately very powerful. A good emacs or vim configuration tailored to your needs can stay with you for decades. It’s stable, reliable, and does everything already. vim has released less than one point update per year for more than 2 years. During that time Sublime and VSCode had dozens, if not hundreds. For most people the choice of editor doesn’t make a huge difference. They spend far more time reading than writing code. Nano is the right choice for you.
