A strong editor is able to overcome this anchoring bias, imagine alternative approaches to the same problem, and evaluate them against each other. This is not easy and requires experience and practice. I am starting to think that a lot of people who "co-write" with ChatGPT are seriously overestimating their own editing skills.
But then again I’ve found a lot of people are not bothered by overly convoluted code that is the equivalent of using a hammer for screws either…
You have to nitpick everything, because there is no actual meaningful aim that is consistent.
I ran across an outsourcer that did the same thing about 20 years ago (near as I could tell he was randomly cutting and pasting random parts of stack overflow answers until it compiled!). We got him away from the code base/fired ASAP because he was an active threat to everyone.
