We've got used to 'reasonable' society and politics in the last few centuries, but check out politics in developing nations or dictatorships, or woke, or Trump or places like pageantry. All fake news and gossip and performance, and AI just makes this potentially much much worse.

It already has a name in academia I think, post-truth, or post-reality or whatever, I think it all started with the French post-modernism thing, then critical theory, etc.

But I'm not sure it's a post- 'advance' at all, but more like a rejection of the enlightenment and a return to the tribal village.
