Don't agree with that at all. If it were simply "repetitive and non-creative", why hire copywriters at all, why not just have the engineers or product managers write the copy? I've worked with good copywriters, and was impressed with the quality of writing they did. The point is that ChatGPT excels at the type of creative writing that previously we thought was solely the domain of humans. I think you are getting things backwards if you think that because ChatGPT can do it that it is repetitive and non-creative.
