If there’s one takeaway from the documentary The Internet’s Own Boy: The Story of Aaron Swartz, which debuted at the Sundance Film Festival last week, it’s the overwhelming sense of what could have been. Prior to his death a year ago this month, Aaron Swartz was facing federal hacking charges, but he was also a strong voice in political activism online. He cofounded Demand Progress. He helped stop SOPA. He warned people about government spying. And, as the film demonstrates, he was a young man with an uncanny ability to explain fantastically complex technological and political topics in layman’s terms — one of the best-equipped people to explain why the very laws used to indict him were so outdated.
