The lies fuel untrust which causes people to seek alternatives. Expecting that people are going to just start trusting those who have shown themselves to be untrustworthy is naive and arrogant which isn't a great combination.
LLM AI, like ChatGPT, will make this problem worse because it is based on information on the internet, which means it has a positive feedback loop towards information that is popular with no ability to fact check. And journalism is being replaced by ChatGPT, so we're headed towards Idiocracy.
