Enabling developers of different talents and backgrounds to be productive and contribute successfully, and to scale up in number of separate teams, is a hard problem and doesn't deserve the kind of dismissiveness you give it here. More powerful languages enable talented developers to be more productive individually, but it's hard to teach all the other developers about the new and interesting abstractions that the powerful languages enable, and it's impossible to hire for them directly. This limits velocity. And it's not just huge corporations, it's any company which is trying to scale from 10 to 100 developers; where you're hiring continuously, where there are too many other developers to efficiently rely on ambient learning.
