If someone is that frustrated with AI, do they not just … switch to not using AI and doing it by hand, asking simpler next-step questions and hand-coding, instead?

But it is futile to get frustrated or annoyed by an LLM. I do get frustrated, too, but I do not "yell" at it hoping that it will miraculously do what I want. GPT (again, free tier, so no wonder) got me frustrated too because I felt like it just would not listen, no matter how specific I was, so yeah I did experience what the author intended to show.
