I can already spot GPT text, tbh. Not definitively, but you can kind of smell it.

recipe websites that use it all have the exact same type of format I've noticed - lots and lots of bullet points and subheadings

I feel this way about reading my students' essays. There's a lack of resolution to AI writing, it glides over the surface like grease

I have a hard time with articles where it’s either ChatGPT or somebody getting paid by the word. The weird extra sentence padding shows up in both.

It scans like an earnest 15 year old writing a class essay

Oh yes

It's uncanny valley but in sentence form.
