As I said that doesn't matter if you are being paid by the word. If the goal is to be paid, who cares where the words come from if the reader laps it up. But if you enjoy writing for it's own sake, and if you are doing because you've found the discipline involved writing something down in a way others will understand is an excellent way to sharpen you're own understanding, then the less a AI is involved the better. Sadly I need a proof reader, an AI does an acceptable job, and they are free, for now.
