This is nonsense. > It is almost certain that if someone is smart enough to build a search engine while living off of ramen, they also know more about what Google is capable of. Well then they should be able to see an argument that comes from someone who doesn't understand the problem space for what it is. If a founder is going to second guess their life's mission because someone said they didn't think it could work, that founder is not very likely to succeed anyway. It boils down to "don't criticize peoples ideas" and it is a terrible idea. Even if you're wrong in your criticism, that's up to others to weigh. I want to hear the bad arguments against me, it helps me articulate to myself more clearly why it would work. And I want to hear good arguments against me, I might learn something.
