“[The] main reasons that motivate editors to add AI-generated content: self-promotion, deliberate hoaxing, and being misinformed into thinking that the generated content is accurate and constructive,”

I think the main driver behind people misinformed about AI content comes from the fact that outside of tech people, most have no idea that AI will:

1. 100% make up answers to things it doesn't know because either the sample size of data they have ingested was to small or was bad. And it will do this with the same robot confidence you get for any other answer.

2. AI that has been fed to much other AI generated content will begin to "hallucinate" and give some wild outputs, very similar to humans suffering from schizophrenia. And again these answers will be given as "fact" with the same robotic confidence.
