Just in renaissance? There is virtually nobody left in the workforce that can write JavaScript. Most of the old timers have gotten out, and the youngsters are an epic example of the article: the loss of perspective to self-reflect due to a machine (library) that does their jobs for them. Case in point: take React and querySelectors away and watch the sadness unfold like an apocalypse movie.

Yes, yes, I know there are still people who can/do write JavaScript... they just are not statistically represented in the workforce.
