I had one contributor who would submit hundreds of lines of disconnected changes. One of his PRs was isolated as being the source of the bug.

After some hours of work, I discovered that his actual semantic change was one line of code, and was the source of the bug. The rest was just reshuffling code around with no apparent purpose.

At a recent meeting, the agenda was generated by LLM. About 20% of the action items were hallucinations.
