You're both right - I did make quite a bit copy-editing for some minor journals published by Japanese scientific societies. But I also experimented a bit last year with using ChatGPT to correct minor spelling and grammatical errors, and it did a credible job. With the right ptompts, you can even get it to do a line by line explanation of the logic behind each of its edits, so it could probably serve as a free, instant and personalized writing tutor as well. I guess its especially well-suited to highly formalized writing styles like those used in research articles.
