I think that piece is half right and half wrong.

I think it's largely correct that hiring bad engineers is dangerous to the company. But that's always been true, especially those "hack out a prototype, get director applause, and leave it for somebody else to own" people. But management has usually chosen to keep such people around, because they can look good on paper (see how many tickets they closed?).

The question is really a management / business-owner question -- will managers/directors stop hiring yolo-engineers? Will they empower engineers to close PRs simply on complexity/size grounds? Will they fund refactors and simplifications as first-class concern? If not, it will be a problem, and I don't envy the engineers who try to be the glue at such a company.
