ENIAC, “the first programmable, electronic, general-purpose digital computer” was built to calculate ballistics tables. The Defense Advanced Research Project was the funding behind the first great age in the development of computers. The Internet was designed as a way for computing infrastructure to withstand nuclear attack. The great engine behind the early development of computation was war - cataclysmic, all-burning, 20th century great-powers war: the coming war that no one would win.
We continue to try to hammer these swords into plowshares and cellphones and video games, but the legacy of war is part of every bit of computation. To build computation for peace we have to encounter and work around and subvert and rewrite the logic and history of war.
Confront the dark parts of your history. Build good things, and admit and work with the possibility of their bad beginnings. Put down your shoulder and push away from the trajectory you have been given, towards something new, and something that is yours.
