Back in the day, when wars were won and lost by whoever had the biggest stick, the US reigned supreme. Nowadays, however, having the fastest jet isn't much use when hackers can attack you on a whim. That's why the Department of Defense has opened its doors to pitches from those outside the defense community to dream up the next generation of digital weapons. The idea is to coax minds from academia and the sort of companies that you read about on a daily basis into coming up with smarter drones, cybersecurity platforms and better conventional weapons. The DoD is hoping that some technologies will be up and running by 2025, hopefully in time to prevent America's film industry being ruined by the targets of its satire.
