We are living in a world in which cows send texts to farmers when they're in heat and the most valuable real estate in New York City houses computers, not people. Robots are delivering cups of coffee, and some of humanity's greatest works are created by crowds. We are in the midst of a networking revolution set to transform the way we connect with one another. Studying biological systems is perhaps the best way to understand such networks, and nature has lesson for us if we care to listen; bigger is rarely better in the long run. The deadliest creature is the mosquito, not the lion. It the quality of network that is important for survival, not the size, and all networks the human brain, Facebook, Google, even the internet itself eventually reach a break point and collapse. That's the bad news. The good news is that reaching a break point can be a step forward, allowing a network to substitute quality for quantity.
