Relevant reading, especially the second article was eye-opening for me when I first read it. I think that partly also applies to you @robbie.morrison . Some people “just write that way”.
And I have come to this thesis statement: I don’t write like ChatGPT. ChatGPT, in its strange, disembodied, globally-sourced way, writes like me. Or, more accurately, it writes like the millions of us who were pushed through a very particular educational and societal pipeline, a pipeline deliberately designed to sandpaper away ambiguity, and forge our thoughts into a very specific, very formal, and very impressive shape.
