I've used AI to re- create the voices of great writers (using their real recorded voices as training material), so that I could create audio books of works they'd written. I had to do a lot of re-runs and editing to make it sound decent.
I think that's a good use of the technology.
But this all-AI-generated content, deployed by people who are no more than money-seekers, is just garbage. Full of mistakes. But worst of all, it's mostly just full of whatever the "conventional view" is of whatever topic is being discussed. Less than worthless and a waste of time. Leads us downward in every way.
