We're never actually going to win this arms race. We need a structural solution. Perhaps we could look into, maybe, decentralizing social media so no single algorithm ends up controlling huge chunks of it?
I support opposing misinformation directly. Hold the authors accountable by making them justify what they say against actual published science. Press them with punishment and make them change their tune. At this point they are a cancer killing humanity and we should have very little humanity left for them.
