"Don't trust what you see on the Internet. Trust instead what you read in a reputable daily newspaper, or Peter Jennings or Tom Brokaw on the nightly news, or BBC World News."
Today, the Internet, especially the part which is not trustable, has nearly finished killing most of the "trustworthy" news sources, by outcompeting them for ad dollars - by being way better at targeting ads (e.g. Meta) and by scientifically perfecting addiction (e.g. TikTok). What remains is mostly controlled by governments and has far from a perfect record of being fact-based and impartial.[1] There are a ton of independent people out there in good faith posting facts on the Internet, but we just agreed that we shouldn't trust what we see on the Internet.
So doesn't this become "Don't trust anything"? And doesn't that, in practice, get implemented as "Don't trust anything that challenges what you believe to be true"? This feels like a really, really bad change to our society - and I'd argue it's already completely happened.

Effective democracy requires an informed voter base. Society requires its constituents to be invested in its continuity. Neither of those is achievable when we completely discard trust.
AI kind of makes this worse, but also only barely. Because most people really ought to know by now that almost any content could be AI, a video of, say, Trump kicking a baby or violating a goat wouldn't convince anyone that those acts happened (unless they already believed they happened).
Thing is, we're so flooded in biased BS, and no one has any incentive to produce non-sensational, factual news. I absolutely see 'post-truth' as the inevitability. You can't "weed a garden" when it is 100% weeds. The term "news" will cease to mean facts, and just become a branch of entertainment. Kind of the way "Reality TV" went from being supposedly a documentary (e.g. COPS) to just being a flavor of entertainment, where nothing needs to be real.
