GPT is so far from threatening “every single person who writes words for a living” anyway. Unless you’re writing generic SEO filler content. Not sure who is claiming that but they don’t understand how it works if they do exist at scale.
Writing has always been a low paid shrinking job well before AI. Besides a tiny group of writers at the big firms. I took a journalism course for fun at UofT in my spare time and the professors had nothing but horror stories for trying to make a job out of writing (ie getting a NYT bestseller and getting $1 cheques in the mail). They basically told the students to only do it as a hobby unless you have some engaged niche audience. Which is more about the writer being interesting rather than the generic writing process.
While AI isn't going to put anyone out of a job immediately (like automation didn't), there are legitimate risks already in that regard -- in both fiction and nonfiction sites, folk are experimenting with having AI basically write stories/pieces for them -- and the results are often good enough to have potentially put someone out of the job of writing a piece in the first place.
