Maybe we just aren't far enough in the vibe coding side of things and there are still too many people in the industry who still pay attention to details, so no major catastrophes haven't happened yet because of vibe coding. So the people who pay attention to details are still carrying their organizations, but I do wonder how long it is going to be sustainable.
When it comes to joy killers because of AI, then it is dismal how plagiarism (going by the definition of "presenting someone else's work without attribution") suddenly became widely accepted. When I see long lists of bullet points with interspersed bold text, I know that it is something the sender did not write or bother reviewing. Absolute cherry on top when in the end of that text you see the typical LLM suggestion that you can ask for more information, which the sender didn't even bother removing.
