Junk like Buzzfeed news and similar sites that just regurgitate other content existed before ChatGPT, I guess those serve some purpose, though I've always thought they mainly exist to host ads and to trap people in a maze of links and pop-ups. ChatGPT can write that junk just as well as a person.
At this point LLM-produced "writing" sticks out because it has no voice, it just repeats and walks around some point derived from the prompt, like someone summarizing Wikipedia articles. I will just click off of that stuff until I find something written by a real person. I hope more people do the same. The novelty will wear off sooner or later and we'll recognize LLM-generated writing as nothing more than vapidly useless filler. In a culture schooled with writing presented as a chore, where the number of words in an essay matters more than an original thought, LLMs promise to relieve a lot of people of the burden of thinking and writing.
