Do you have inside information that we do not on how this technology works? No offense, but your degree means you know a certain determined extent of human knowledge of a subject. It does not mean you know the secrets of the universe, including every human invention that can and will exist. If this was the case, your rockets would be landing themselves instead of SpaceX. I'd also like to point out the quantity of PhD holders that stood in the way of SpaceX and many other revolutionary companies that have brought about technological change. Let's see the data first, or did they not teach you the scientific method while you were obtaining that fancy degree?
