However, polished to a point that we humans start to lose our unique tone is what style guides that go into the minutiae of comma placement try do do. And I'm currently reading a book I'm 100% sure has been edited by an expert human editor that did quite the job of taking away all the uniqueness of the work. So, we can't just blame the LLMs for making things more gray when we have historically paid other people to do it.
Even if the text is a simple article, a personal touch / style will go a long way to make it more pleasant to read.
LLMs are just making everything equally average, minus their own imperfections. Moving forward, they will in-breed while everything becomes progressively worse.
That's death to our culture.
