Purposefully ignoring the second part.

First, what really matters is the vi part of vim, i.e the idea of commands, text objects, motions,... The rest are very useful features that are nice to have especially in a programming context (quickfix list, makeprg, window and buffer management, macros,...).

The first part makes editing text so much easier. Even in the day of prompting, they're still useful to have in any text editor. It takes typing text from a chore to a fun activity.
