I don't mind interacting with LLMs myself and find they increase my productivity a decent amount. I just can't stand dealing with other people's slop.
Getting sent IM responses that are copy pasted LLM nonsense. Getting a massive PR to review that was generated overnight and the author didn't read it first.
So annoying, I'm dealing with a client that just constantly feeds my responses to their question into AI. Which of course just asks more questions and tells me how clever I am. I also know the client isn't reading because in many spots I put "[Client Name] you need to answer this directly as we need to know the actual real business detail" and its ignored or the AI provides a detail I know is made up.
