Found this at TUAW (a Mac site) today.
Also to be found within the exhaustive look at Siri's backstory is the tale of how the concepts behind [the] software got their start as a project of the US Department of Defense. Only instead of finding nearby restaurants and setting alarms, the goal of creating a military-grade virtual assistant was to aid top brass in day-to-day base operations and other important tasks. We can't help but shudder at the idea of it interpreting a general's request to "order some flowers for mom" as "deploy all our nuclear bombs."If you've interacted with Siri, you know how frightening that prospect is. The software is easily confused. Siri on the battlefied? Horrors.
