This entire article is about the fact that the codebase deteriorates over time when you work this way. If they are correct, it will take longer and longer to develop PRs, and more and more cycles to QA them. Eventually the code will be unsalvageable and it might get there before anyone notices a problem. I don’t know if they are right but I know codebases can get there with humans at the helm - and the humans can adapt and learn.

This is not a certain fate but it sure looks likely and is a serious risk. Some software is so low stakes that you can get away with it I’m sure - there are always trade offs.
