> Surely they are hiring world-class devs, so what’s holding them back? Facebook Engineering has a notorious "not invented by me" culture, it's not unique there but a lot of our "world-class" engineers are just acting economically rationally and hole-digging on some new bespoke framework or tool to cement their position in the company. You end up with a massive amount of churn and over-engineered vanity projects, and it's manifesting downstream in basically every product we've turned out for the last five years. That's why the applications bloated and terrible. The joke inside the company is that it used to be "move fast and break things" but now it's "breakfast, vest and move things around". It's really an engineering culture of decadence and waste these days.
