We don't live in a post-truth world. We live in a post-truth culture. There's a difference. The real world doesn't give a shit what you believe, and that's exactly why inaccurate beliefs can cause so much pain. The good news is that a post-truth culture is in no way sustainable for that very reason. The bad news is that it's death and the filling of its niche with something better could be incredibly painful if we just let things run their natural course on their own.
