The U.S. Defense Department has updated its guidance on autonomous weapons to take into account AI's "increasing role" in warfare.   The policy directive, "Autonomy in Weapons Systems," now includes some clarifications and changes to account for a "dramatic, expanded vision for the role of artificial intelligence in the future of the American military," according to the Pentagon's Director of Emerging Capabilities Policy, Michael Horowitz. The update, which is the first to the policy directive since 2012, cements the U.S. military's aim to incorporate more advanced AI and review that technology before it's used. According to Horowitz, it lays out the responsibilities and guidelines that the Pentagon should consider when developing and developing autonomous weapons and other systems. In the case of AI, it includes some updates regarding the future of ethical AI and the need to additionally test and review AI systems before deployment. It also calls for the creation of a new senior-level oversight group, chaired by the undersecretary of defense for policy, that would oversee autonomous weapons systems. "The directive now makes explicit the need for an autonomous weapon system, if it's approved, to be reviewed," Horowitz said.
