This happened to me. Uber-qualified graduate came in as a decision maker, fucked a load of stuff up, then left. Then the tenured devs gradually started leaving in revolt. Then the product died.
Sounds familiar. I worked at a bank once that had the brilliant idea of swapping out Angular with Polymer, because an early 30s guy with Google in his CV became the new CTO and Decided that it should be Polymer / web components.
They were just about finished with making their Polymer 1.x components ready for Polymer 2 when the Polymer project once again did an overhaul and split off to lit-html or whatever.
I mean they picked an experimental / in development project that was best known for running McDonalds menu displays. We had to fix basics like memory leaks because it didn't have proper routing - it wasn't a web application framework, but they tried to use it as such.
