A coworker is trying to get everyone at work to just vibe code everything and today in a meeting he said something along the lines of "I know today that we rely on internal expertise, but I don't think we should do that anymore". Buddy if we can't rely on internal expertise how the fuck are we supposed to validate the output of these LLMs? We can't trust the LLM to validate itself. It was faking the tests in his PR. It wrote dozens of tests that asserted nothing, but he didn't see a problem with that because the test coverage was higher than average.
