I wonder at what point we're just going to see people writing like AI because they read it so much? That said I'm fine with companies saving money on copywriters
I don't think this is true. Someone probably had to write like this, but a base model has to be able to write like anyone. The specific mannerisms of AI appear in post training, either as things that are rewarded or as mode collapse artifacts. ChatGPT didn't get obsessed with goblins because that's incredibly common among humans.
