Understood. But the Earth doesn’t exactly hide its sand, the source of silicon. Liu’s doctoral research at UC Berkeley in the 1970s was on the serendipitous ways that ions behave when shot into silicon; he means it’s _atoms_ that God has secreted away. These indestructible treasures have always been buried in matter, awaiting the invention of scanning electron microscopes and scientists with enough assiduity to spend decades on end peering into their atomic eyes. “There's no way out,” Liu tells me. “You always feel you are scratching the surface. Until, one day, it’s revealed to you.” His guileless manner and expansive sense of wonder must be unique among CEOs of global megacompanies. Nothing about him comes off as shady or cheap like Elon Musk or the Overstock person. I remember a phrase from the liturgy of my childhood church: gladness and singleness of heart. That is Liu.
