As someone working on LLM-based stuff, this is a terrible idea with current models and techniques unless they have a dedicated team of human editors to make sure the AI doesn't go off the rails, to say nothing of the cruelty of firing people to save maybe a few hundred thousand dollars with a substantial drop in quality. They can be very smart with proper prompting, but are also inconsistent and require a lot of handholding for anything requiring executive function or deliberation (like... writing an article meant to make a point). It might be possible with current models, but the field is way too new and techniques too crude to make this work without a few million dollars in R&D, at which point it'll probably be completely wasted when new developments come out nearly every week anyway.
