We have a notorious junior LLM addict in the team. All experienced engineers are extremely annoyed reviewing his code due to endless stream of merge requests containing repetitive code which often plainly doesn't work in any other than the happiest of scenarios and the fact that it doesn't work can be seen from space (i.e. no testing needed, it's obvious while reviewing).
While every single developer now uses LLM, the outcome really depends on how one is using it.
