“The stuff you dig out of the earth’s crust becomes, in an information economy, less important than the information that informs it, what you think about the stuff. Yet the more you ponder that information, the more you understand about that stuff, the more real the stuff becomes. To put it in terms of the art world Andy Warhol lived in, the more you see that style matters more than substance, the more you see the vital role, the vitality, of substance.”
