Perhaps I'm overly an optimist, but I have a feeling we will develop the informational and psychological technology to combat the destructive misinformation campaigns that brainwash people into harming their children with anti-vaccine beliefs.

We are not there yet, because the destructive media forces are too new and we haven't developed defenses against information diseases like RFK Jr. But we will get there. Two steps forward, one step back.

Who is we, who will pay for it, and how will such informational inoculation benefit the rich?

The current media status quo, and its consequences does, which is why we get to enjoy it.
