Humanity, collectively, has to see who these people are and what they are attempting, and that history needs to be recorded immutably for all time.

Excellent point. There has to be a pretty dramatic shift in the way people view things.

Your post made me think of what it must have been like during the Reformation. The Catholic church had a hold on everything. Their system of having to confess sins to priests gave those priests a psychological hold over everyone but only as long as people continued to believe. It must have been wrenching to discover that everything you had been brought up to believe in was so corrupt and self-serving. And the shift away to Protestant belief certainly didn't happen overnight.

We're taught about those time periods in a dry fashion and I think we really don't connect with what the normies of the time went through. But you can see parallels to today's events. The difference this time is the Internet and mass communication. Something that has global reach so that we're not depending on riders on horseback or sailing ships to bring new knowledge. It's going to happen much faster but it's still going to take time to get people on board. And not everyone is going to want to get on board. Reformation happened and the Catholic Church kept chugging on.
