Yup, this was my first thought. Tell an LLM that there's a bug, and it will _happily_ add 200 lines to the project, usually wrapped in if statements so that it all interleaves with existing code. Then it will write twice as many lines in tests, run it all, and be done. Your bug is fixed. All the tests run, and test coverage went up. Now do that a couple dozen more times. :shudder:
