"I happen to be somewhat skeptical about the idea that there really is an objective way of kind of, I guess. graining information," he says. "Do we think that an alien species would be wrong for having some very interested in very different kind of coarse granings or would it be impossible for aliens to have interests in very different kinds of coarse graning?" He adds: "A thought experiment I'd love to do in reality is to take like a thousand births and have humans evolve intelligently and then let science progress independently"
