AI-written articles tend to be far more regurgitative, lower in value, and easier to ghostwrite with intent to manipulate the narrative.

Economic value or not, AI-generated content should be labeled, and trying to pass it as human-written should be illegal, regardless of how used to AI content people do or don't become.

My theory is that AI writes the way it does because it was trained on a lot of modern (organic) journalism.

So many words to say so little, just so they can put ads between every paragraph.

That is low quality articles in general. Have you never seen how hundreds of news sites will regurgitate the same story of another. This was happening long before AI. High quality AI written articles will still be high value.
