Maybe I'll go watch the video, but here is the problem with QT.
For anything you can calculate with Quantum Mechanics, the opposite can be calculated with as much enthusiasm. It's rather like the ancient engineers. They built methods for kingdoms to conquer other kingdoms. Then they went to the other kingdoms and built methods of defense against their own armament.
The greatest advantage we have with Quantum is that it shows us how to be believers in whatever we are doing. The way it does this can be rather complex at times. But it is the complexity that strengthens our belief.
