How to convince people that this system works without to test it first? I can't accept a theory without evidence. This is not the scientific way.
Have you tested to see if jumping off a cliff will kill you? What evidence do you need? RBE has a plethora of evidence. The difference is, it won't kill you if you try it yourself.
Jumping off a cliff is a poor analogy, it's both intuitive and has been tested. Proof of concept is important.
