I know a person. Ex-Googly. Doing his startup. Spent one year on a crazy complex product. Investors do not get it. Users do not get it. He spends 99% of the time explaining why his ideas are so good. You ask to try the product, weeks pass and just slides and video demos. When you eventually try it, it's so confusing and nothing really works. I tried to make him understand that the constraint he needs to fit is users being able to understand rapidly why it's useful to them and that it should work. He does not care. He says it's about the story, and that the story will drive millions unlocking a super big team building his idea. I said that's cool but why in the meantime you don't just go with one thing that is useful and works and then procedurally evolve to your vision while you interact with the user and discover more about their problems. The answer was a one-hour speech on Google leveling system. Maybe he is right. Time will tell.
