The first thing I thought of when I saw this is that some mid-tier dictatorships could replace a lot of their newscasters with this approach. Can always guarantee they’ll say what they need to say, and a lack of emotion is a plus maybe? Except with the dear leader passes then you bring out a real person for the emotions.

Well if the article is to be believed, they actually can't guarantee they'll say what they need to say, but I think your larger point holds.

AI's not mandatory for that
