  You have to unleash yourself from conventional thought. It's what's
holding us back technologically. If some scientist today comes up with some
radically new theory, the first thing other scientists do is rip it apart
rather that collaborate to get results. So long as that thinking continues
we'll never make significant progress into new technologies.
