I'm looking forward to reading Bruce Schneier's latest.

"My central metaphor is the Prisoner's Dilemma, which nicely exposes the tension between group interest and self-interest. And the dilemma even gives us a terminology to use: cooperators act in the group interest, and defectors act in their own selfish interest, to the detriment of the group. Too many defectors, and everyone suffers -- often catastrophically.....

Also -- and this is the final kicker -- not all defectors are bad. If you think about the notions of cooperating and defecting, they're defined in terms of the societal norm. Cooperators are people who follow the formal or informal rules of society. Defectors are people who, for whatever reason, break the rules. That definition says nothing about the absolute morality of the society or its rules. When society is in the wrong, it's defectors who are in the vanguard for change. So it was defectors who helped escaped slaves in the antebellum American South. It's defectors who are agitating to overthrow repressive regimes in the Middle East. And it's defectors who are fueling the Occupy Wall Street movement. Without defectors, society stagnates.
We simultaneously need more societal pressure to deal with the effects of technology, and less societal pressure to ensure an open, free, and evolving society. This is our big challenge for the coming decade."
