Hundreds of academics have urged Google to abandon its work on a U.S. Department of Defense-led drone program codenamed Project Maven. An open letter calling for change was published Monday by the International Committee for Robot Arms Control (ICRAC). The project is formally known as the Algorithmic Warfare Cross-Functional Team. Its objective is to turn the enormous volume of data available to DoD into actionable intelligence. More than 3,000 Google staffers signed a petition in April in protest at the company's focus on warfare. We believe that Google should not be in the business of war, it read. Therefore we ask that Project Maven be cancelled. The ICRAC warned this week the project could potentially be mixed with general user data and exploited to aid targeted killing. Currently, its letter has nearly 500 signatures. It stated: We are ... deeply concerned about the possible integration of Googles data on peoples everyday lives with military surveillance data, and its combined application to targeted killing ... Google has moved into military work without subjecting itself to public debate or deliberation. While Google regularly decides the future of technology without democratic public engagement, its entry into military technologies casts the problems of private control of information infrastructure into high relief. Lieutenant Colonel Garry Floyd, deputy chief of the Algorithmic Warfare Cross Functional Team, said ... earlier this month that Maven was already active in five or six combat locations.
