"You never understood games. Maybe that's why the world was such a mystery to you." — Daniel Suárez

He was beginning to feel the rush now. This wasn't a game, and it was clearly designed by a well-funded and technologically capable person. He had always sought the edge—and this was it. This was as far from Main Street as he'd ever been. This wasn't the tattooed, pierced, neo-tribal rebellious bullshit of his generation. This was a quiet demonstration of networked power. This was it.

"Sexual reproduction exists solely as a means to defeat parasites. By mixing male and female genes, sex produces offspring not exactly like either the male or female—making each generation different from the last, and presenting a moving target to intruders intent on compromising this system. … Even with this variation, parasites continue to pose a threat... and parasitism evolves and moves through any system—not just living things. The less variation there is in a system, the more readily parasites will evolve to infest it..."

"Let me tell you the story of the most successful organism of all time: this is the story of the parasite. … Early on, evolution branched into two distinct paths: independent organisms—those that exist on their own in the natural world—and parasites—organisms that live on other organisms. And it was, by far, the parasites that proved the more successful of the two branches. Today, for every independent organism in nature, there exist three parasites. … These two strains of evolution have been locked in a primordial arms race, constantly evolving to best each other for supremacy of this planet. As parasites evolve to perfect their systems against a species of host, the host evolves to evade their attack. Scientists call this theory of an eternal genetic struggle the Red Queen Hypothesis—a name taken from Lewis Carroll's Through the Looking Glass."
