I got accused (more as a joke, but c’mon) by my boss the other day for using GPT to write a document. His justification: the grammar and spelling was too good. I had no idea that good writing was now a “tell” for generated content for some. I I just write good, honest!
However, I understand that you do not know me and that you are describing a hypothetical person who writes carefully about bland subjects.
Overall, I am sure that you are correct and that this is one metric used for identifying AI-generated content.

Seriously, though, I feel like the words "however" and "overall" will be tainted for years.
