Elon promotes this idea and people believe it to be possible, then suddenly it becomes possible. It makes me wonder how many breakthrough ideas are out there, that are undiscovered.
Clearly Elon is a genius. How much more of a genius would he be if he knew this principle of human nature, and used it to find the solution to a problem that he hasn't figured out. He would use the collective intelligence of the world to solve the problem.
He probably has a reasonable idea that this can be done, but what if he were to use this power he has to essentially scale his genius by harnessing the imaginations of people like you around the world?
