It's because no matter how 'good' the AI output is, "vibe coding" is strongly associated with "completely unreviewed and untested". LLMs have brought the skill floor straight through the ground and into the depths of hell, so people are doubly cautious with it because there's a very good chance with any vibe coded app that there's not a single person in the world that truly understands what it actually does just behind the scenes. It could be completely fine, or it could be breaking your system or uploading your sensitive data somewhere because the vibe coder provided flawed instructions or the LLM decided to make an unexpected 'optimization'. Wanna roll the dice and find out which one it is?
