I think this equation completely forgets to take into account the power of the people you tell about your ideas. If you are studying in Stanford and can literally walk into the office of professor X and tell him about your ideas (which worked pretty well for Elizabeth Holmes and professor Channing Robertson but that's a different story) you have an enormous competitive advantage. And if you have a Stanford professor on your side, it's pretty easy to open doors to other influential people.

On the other hand, if you tell your idea some stranger on the Internet... chances are much lower that you will find the right people.
