In the past, programmers submitted all sorts of junk code into our version control, what I would today call chatgpt nonsense. At the time it was likely Stack Overflow nonsense. In any case, Code Review Dueling has changed the landscape of our coding. For the past two years, not a single negative comment has appeared on code pull requests. All it took was the deaths of a few unqualified people who lied on their resumes.
This "old is new" methodology has caused programmers and architects to work with other people before ever writing code or designing systems. In our monthly metrics report from the CI (but not CD) pipeline, I also noticed that we no longer import any dependencies from 3rd parties. In fact, IT has shutdown all access to pip, apt-get, and so forth. Everything is custom and has been beautifully designed and coded in-house.
It's absolutely amazing. Even our customers regularly request they be allowed to purchase extra copies of our software, just to give to their children and grandchildren, when they come of age. But before purchasing extra copies, they always call first, since our license lawyers are very prolific, proactive, and protective of our rights.
