Unfortunately the majority of people are idiots who just do this in real life, parroting populous ideology without understanding anything more than the proper catchphrase du jour. And there are many employed professionals who are paid to read a script, or output mundane marketing content, or any "content". And for that, LLMs are great.

It's the elevator operator of technology as applied to creative writers. Instead of "hey intern, write the next article about 25 things these idiots need to buy and make sure 90% of them are from our sponsors" it goes to AI. The writer was never going to purchase a few different types of each product category, blindly test them and write a real article. They are just shilling crap they are paid to shill making it look "organic" because many humans are too stupid to not know it's a giant paid for ad.
