Are you saying that because journalism is trash, that AI trash is okay?
AI generated "content" is just fulfilling the demand. Before AI we had army of human copywriters, the same person would write articles about movies and nuclear physics. And lets not forget SEO spam and SEO farms.
AI is just generating slop in a cheaper way, and much faster.
No, people will demand more of what they really know, if you feed them with better things they will demand more better things.
But the point is, the cheap news are related to junky ads and this is the point where it gets spoiled: selling shit is easier when is tied to spreading shit.
Fix the greed behind the news distribution and you will have better content plus a demand for a better content.
