The system, lol, I mean our culture and society, is very resilient to change. If it wasn't, it would be a different system. A part of the resilience, the reason it doesn't crash down into chaos and anarchy is because it rejects and ostracizes people with new ideas. It's by design, how it evolved. However, it also needs to evolve and grow and the people who do that have to endure.
Not all people who are on this 'Hero's Journey' are correct. Disney isn't addressing whether the crazy new idea is good or not, although in their media it is always a good idea, which is what Paul Graham is writing about. Their stories are addressing the journey a person endures if they have any crazy new idea that challenges their culture and society, good or bad. Whereas, Paul Graham is looking to quantify signals that a crazy new idea is good, something he should invest in. To which, I'd add asking if the person with a crazy new idea is honest, not only to other people, but more importantly honest to themselves, integrity. If a person can separate delusion from fact except for that one idea, that's a signal.
