We, as humans, are well beyond being mentally ready for the internet and social media alone. Most of the key communication of the 20th Century was based on a tradition of duty and service in reporting and, generally, leadership. The Natzis of the 40s died not because the idea was 'wrong' (which it was) but because bad leadership and greed caused extinction. Before Poland, Europe was plenty happy letting Hitler be. Why was Hitler successful? Because he told people what they wanted to hear. You are better. We are better. We deserve more. It's their fault we are like this.

Self bias is the critical failure of the human mind. Tell someone that they deserve more and that they are better than others and they will believe you.

In a world where politicians and companies (same thing really) can use AI to collect your online persona and then fill your day with advertising designed just for you, telling you that you are right and it is 'them' who are wrong will work on nearly everyone. It already does. People watch news channels and follow influencers that make their feeds echo chambers, it drives extremism. How does a society tell you that you are wrong, that the other person is right?

Humanity and humankind made Hitler. Humanity and human kind will make tools that succeed at their goals to make others do what they want. We are already in freefall, this is a rocket booster on our back.
