We walk a delicate line, perpetuating Atreides (Siona) genes in our population because that hides us from prescience. We carry the Kwisatz Haderach in that bag! Willfulness created Muad'Dib. Prophets make predictions come true! Will we ever again dare ignore our Tao sense and cater to a culture that hates chance and begs for prophecy?
