Oh come on, are you 12? Real life doesn’t have narrative arcs like that. This is a real problem. We’re not gonna just sit around and then enjoy a cathartic resolution.
Anyway I think GP has a point worth considering. I have had a related hope in the context of journalism / chain of trust that was mentioned above: if anyone can produce a Faux News Channel tailored to their own quirks on demand, and can see everyone else doing the same, will it become common knowledge that Stuff Can Be Fake, and motivate people to explicitly decide about trust beyond "Trust Screens"?
