Another problem I've realized today, is the proliferation of data that was originally hallucinated by AI.
I was discussing an issue on a software with a coworker and he asked an AI for help configure around it. He then sent me "apparently we can try changing this setting to this value". I told him to first validate if that setting really existed because AI tends to make up things like that when it's what you would want to hear and running a test would take us 20~30 minutes.
He found some discussions about that setting not working as people expected. "ok at least it exists then" and we tried it. It didn't work. I later cloned the source of that software and checked, the setting didn't exist - ever.
