I would imagine it is like transcribing, an industry I was in for a little bit when I was younger. I saw the same transition there and imagine it will be elsewhere. First it's a bunch of people saying "AI can't take our jobs, our jobs are thinking jobs." Then it's "Sure, you could use AI, but there's no real advantage to it because it makes so many mistakes."

But pretty soon after that it's "Why am I paying a transcriptionist $3/minute when I can just have the machine auto-transcribe it and then my admin assistant can just scan it for mistakes."

Even if there still IS a quality difference between great writers and AI product, "good enough" is good enough for most customers, especially if you have to pay professional rates to get better.
