Vibe coding was something silly and scary about a year ago. Even then it was a conversation mostly held by people that have never actually worked in software development professionally. Most of the risk with it was associated with junior devs or non-devs vibe-coding and committing crappy code. However that has not really been an issue in the professional world, because there are processes to prevent it and people (for the most part) are much more responsible. People do their own reviews and everything typically has to go through a PR process.
