"There is a very significant skill gap, often driven by enthusiasm"

Honestly I think its more down to experience.

I know relatively inexperienced developers chasing every new tech on the hype train. And I know others that have been around a while and recognise the new tech as a rehash of something from 20 years ago, with some new marketing.

(To be fair I think you need some enthusiasm as well as the experience otherwise you get the "1 year of experience ten times" developers).
