Remember that network power, the power that we’re trying to figure out how to bend and shape for our own security, exists in a kind of dynamic tension. It’s like a stretched, taut fabric spread between concentrated cores and billions of connected users or devices. The logic of spreading and distributed power, the force that makes the network bigger, is driven by Baran’s principle of open design, and by our own hunger for communications and connection and cool new devices. But there is another side to this tension. In a sense, over the years, a whole set of hot, infectious pressures descended on the network of values and friendships and easy cooperation of the Hack-Tic days. “Be generous in what you receive,” had let the networks of our age grow at an incredible pace, but at the price of vulnerability, of commercial ambition, and of an eerie technological lemma that what made the systems faster and stronger might also kill them. A change in culture of the digital elite, naturally, followed. The brutal, inarguable, profitable demands of power and politics had cracked apart the unique social webs of the HacTic era. I did not like watching this sad evolution; none of us did, but anyhow it has produced the world in which our new sensibility will have to operate. The openness that we loved and craved in so many areas of life, from our minds to our markets, had now become a liability. “I remember what the Internet was like before it was being watched and there had never been anything in the history of man that is like it,” Edward Snowden once observed, nostalgic for the datascape he saw melt away during his time at the NSA. 157 I realize now that there is a whole new generation of young programmers that won't ever know that original generous ethos of a place like Hacktic, a fresh cohort of the digital age that operates at levels of technical mastery far beyond anything we might have imag
