I'm a vi(m) user, but I have to say - it's not a fundamental part of computing at all. It's just a very popular tool. A lot of people don't know how to use it and manage to make amazing things.

there's no better way to learn something difficult than to learn it when you're young

Hmm, define 'young'. I'm in my late 20s and I find it easier to learn new things more than ever - including things I failed to learn in my teens and early 20s. Maybe I'm just a late bloomer, and it took me a while to "learn how to learn". But maybe I'm still young in the eyes of someone who has been using vi for 30 years (:
