When journalist Sebastian Mallaby approached Demis Hassabis, Google's AI chief and a man with a lifelong mission to build superintelligence, about writing his biography, he made the following pitch: "If you're going to disrupt people from head to toe, you owe them an explanation of why you're doing it.
