One moment of incompetence can be fatal. - Frank Herbert

Beyond a critical point within a finite space, freedom diminishes as numbers increase. This is as true of humans as it is of gas molecules in a sealed flask. The human question is not how many can possibly survive within the system, but what kind of existence is possible for those who so survive.

I realize that humans cannot bear very much reality. Most lives are a flight from selfhood. Most prefer the truths of the stable. You stick your heads into the stanchions and munch contentedly until you die. Others use you for their purposes. Not once do you live outside the stable to lift your head and be your own creature. Muad'Dib came to tell you about that. Without understanding his message, you cannot revere him!

Be prepared to appreciate what you meet.
