There's this hypothesis that the front end workforce is much younger than the general IT workforce - years ago it was said the mean retention in the front end business was like five years (note I'm not claiming but merely citing this here). A high churn rate could then be a consequence of one generation trying to make sense of web front end work and inventing tools and frameworks seen adequate for the purpose, with some tools sometimes merely representing a trail of knowledge acquisition, with the next generation dismissing what came before and into the habit of carving their own niche, ecosystem, and peer group for their career.
