Earlier quoted context omitted.
I don't! That's just a dumb joke. A thing that I semi-seriously think: modal editing is not some uniquely interesting or advantageous way to navigate and edit text. A thing that I mostly-seriously think: most more recent methods for editing and navigating code are a lot better vim-style modal text editing.
The only thing what makes modal editing bearable (from UX PoV) is the unlimited undo. e.g. Would anyone take a plane that has modal cockpit buttons?
The big thing that classic vi got wrong with modes from a usability perspective is that changing modes is mostly invisible. In vim, however, you can configure it to change the cursor shape in different modes, and this is a pretty effective cue. (It's also the default behavior in gvim.)
