The artificial intelligence (AI) community has a clear message for researchers in South Korea: Don't make killer robots. Nearly 60 AI and robotics experts from almost 30 countries have signed an open letter calling for a boycott against KAIST, a public university in Daejeon, South Korea, that has been reported to be "develop[ing] artificial intelligence technologies to be applied to military weapons, joining the global competition to develop autonomous arms," the open letter said. In other words, KAIST might be researching how to make military-grade AI weapons.
