I'm not confident that's an issue. The press usually takes the party line anyway. In any case where the press feels compelled to not take the party line (it's happened now and then), they've spoken out. I think if the press felt it necessary, they could do a "special" presentation when they feel necessary.

Honestly, I don't see a lot of difference between them and the way Sean Hannity blatantly takes the Trump line. The difference is that in the US, there's diversity of press and so diversity of opinions. I'm not confident there was ever diversity of press in China in the first place, so I'm not sure how much this changes. Maybe if the entire press cycle gets completely automated with no human oversight at all, OK. But I imagine there will always be human oversight, just because they don't want things to go off the rails. That's what happens right now.

And if we reach the singularity, I'm sure an AI would have more guts to stand up and say what's on their mind than a human would.
