>In an AI future, mediocre anything will not exist anymore.

Right! Aren't we all mediocre before we're excellent? Isn't every entry level job some version of trying to get past being mediocre? i.e. Isn't a jr developer "mediocre" compared to a senior dev? If AI replaces the jr dev, how will anyone become a senior dev if they never got the chance to gain experience to become less mediocre?
