“There is no indisputable proof for the big bang," said Hollus. "And there is none for evolution. And yet you accept those. Why hold the question of whether there is a creator to a higher standard?”

“It is either coincidence piled on top of coincidence," said Hollus, "or it is deliberate design.”

“If theft is advantageous to everyone who succeeds at it, and adultery is a good strategy, at least for males, for increasing presence in the gene pool, why do we feel they are wrong? Shouldn't the only morality that evolution produces be the kind Bill Clinton had - being sorry you got caught?”

“He had a collection of science-fiction films on DVD and Blu-ray discs, and although he said he’d seen most of them before, Caitlin was surprised to discover how many of the cases were still shrink-wrapped. “Why’d you buy them if you weren’t going to watch them?” she asked. He looked at the tall, thin cabinets that contained the movies and seemed to ponder the question. “My childhood was on sale,” he said at last, “so I bought it.”

“And Wolfram knows about cellular automata?” “Oh, my goodness, yes,” said Anna. “He wrote a book you could kill a man with—twelve hundred pages—called A New Kind of Science. It’s all about them.” “We should totally ask him what he thinks!” Caitlin said.”

“All right,” he said. “Since you asked, Webmind is an emergent quantum-computational system based on a stable null-sigma condensate that resists decoherence thanks to constructive feedback loops.” He turned to the blackboard, scooped up a piece of chalk, and began writing rapidly. “See,” he said, “using Dirac notation, if we let Webmind’s default conscious state be represented by a bra of phi and a ket of psi, then this would be the einselected basis.” His chalk flew across the board again. “Now, we can get the vector basis of the total combined Webmind alpha-state consciousness...”

“Mr. Lockery—my biology teacher—says if dinosaurs were magically brought forward in time today, we’d have nothing to worry about. Dogs, wolves, and bears would make short work of tyrannosaurs.” She nodded at Schrödinger, who was now padding across the floor in the opposite direction. “Big cats, too. They’re faster, tougher, and brighter than anything that existed seventy million years ago. Everything is always ramping up, always escalating.”
