Are comments like this productive? What is the point of just vaguely guessing that someone used AI to write something, with 0 proof other than some dim pattern-recognition comment? Is it possible that the opposite is true, ChatGPT was trained on writing (like this) and now mimics how good writers speak?
This seems far more likely than anything else. Every technique in the article is practically textbook "writing". Very little personality, but a whole lot of "academic phraseology".
Comments like these are like hearing a baroque harpsichord and thinking "gee, that sounds just like my synthesizer..."
