There is no journalism.

It is, and for a long time has only been, about controlling the narrative.
So, an AI is quite easy to write, it just has to use certain key trigger words in a word salad.

No news or information really has to be conveyed.

Besides, most pieces published in the "news" are carefully crafted by the corporations that benefit from the news. They are just advertisements masquerading as news. Being able to blame this, if ever called out, on an AI will be totally great scape goat.
