1) This is an ego problem. Whoever is doing the development cannot handle being called out on certain software architecture / coding mistakes, so it becomes "nitpicking".
2) The software shop has a "ship out faster, cut corners" culture, which at that point might as well turn off the AI review bot.
I’ve found it’s nice to talk to an LLM about personal issues because I know it’s not a real person judging me. Maybe if the comments were kept private with the dev, it’d be more just a coaching tool that didn’t feel like a criticism?
This goes both ways. I worked for a company where the majority of PR comments were of the "Well, _I_ wouldn't do it this way." form. In some cases, the "way" they were complaining about were direct versions of examples in the language library docs.
One specific case was a PR was held up from merging because I used the plural of "regex" as "regexen" and not "regexes". IN A COMMENT. <eye roll>
