Most bugs that are reported via AI-generated GitHub issues are edge cases, which are technically bugs, but not something anyone actually ran into.
Contributions are exclusively AI-generated, and it's much easier to just go off of a GitHub issue myself than asking the bot behind the GH account to remove the 5 redundant tests it added, or to refactor what has become a 3k line file.
AI doesn't care about code quality, maintenability, or long term goals. It's just a local maximum optimized with RL. Great for debugging, OK for reviews, but can't produce anything that's above average.
