Tech giant Google, who have been caught in the past helping the U.S. government spy on innocent people, has has quietly secured a contract to work with the Defense Department on a pilot, dubbed “Project Maven.” The contract is aimed at helping the U.S. military use artificial intelligence to target drone strikes, and analyze the massive trove of video collected by surveillance cameras on the U.S. government’s fleet of more than 1,000 drones.

Targeting lethal military weapons with artificial intelligence is reckless. Artificial intelligence algorithms have been shown to be inaccurate and exhibit bias. On YouTube this might mean that you just end up watching a weird video. With Project Maven, it could mean the death of innocent civilians. And once the government has this technology, they’ll inevitably use it for mass surveillance and other programs that undermine civil liberties and human rights.

Sign the petition to tell Google: “What happened to ‘Don’t be evil’?! Drop your Defense Department contract for Project Maven. Don’t help the government make algorithms that decide who lives and dies.”
