Vi(m) favors “easy to use” over “easy to learn” - which is the right tradeoff for a tool that one can use for hours a day for decades.

Though I always liked the line, “Vi is user-friendly - it’s just picky about who its friends are”.

(BTW, “ZZ” is usually the right answer to quitting/exiting - still funny to see, decades on, people teaching “:wq<return>”.)
