This is why in order to inspire change most people truly do not matter. I know it sounds awful to say, and it is, but you can safely ignore 80% of the world. 

If you're building something revolutionary you need to convince the top 20% of the 20% of people that are not NPCs. As soon as change happens it will propagate up to the NPCs, it has happened time and again in history. 

To me, this is a liberating perspective. Trying to convince 8 billion people of anything sounds like an impossibly daunting task, who could possibly do that? While convincing 300 million people is still impossibly hard but much much easier. And this scales, convince 20% of them and it slowly propagates down the chain, eventually reaching the NPCs who just do what everyone else is doing.
