Killer AI already exists in the form of drones, and every country is pursuing it.

The claim has two parts: (1) lethal drones with AI or autonomous targeting existed by August 2025; (2) every country, read reasonably as essentially all major military powers, is pursuing them. True: credible reporting (UN reports, defence ministries, major outlets, think tanks) documents that drones with autonomous or AI-assisted targeting have been fielded or used in combat, and that most major militaries have such programmes. Mostly true: both parts hold broadly, but the autonomy is mainly AI-assisted rather than fully autonomous. Mixed: one part holds and the other does not, for example AI drones exist but only a handful of countries pursue them. Mostly false: drones exist but have essentially no AI or autonomous lethal capability, so the claim stretches remote-piloted drones into 'killer AI'. False: there is no evidence of AI-enabled lethal drones and no widespread pursuit of them.

   “Documented cases of use are still rare, but the first was probably in Libya in 2020, where, according to a report by the UN Security Council Panel of Experts, a Turkish Kargu-2 drone allegedly attacked a human autonomously.”

   “As of 2025, most military drones (including unmanned aerial vehicles and unmanned combat aerial vehicles) and military robots are not truly autonomous, as they still require human control.”

   “The spread of decades-old precision guidance technology with advances in artificial intelligence and commercial manufacturing means that nearly every armed actor around the world now has access to rudimentary forms of AI-enabled strike capabilities.”

E2 cites a UN Security Council Panel of Experts report saying a Kargu-2 drone allegedly attacked a person autonomously in Libya in 2020, though it says documented cases are rare. E3 states that as of 2025 most military drones were not truly autonomous and still needed human control. E4 reports that nearly every armed actor has access to rudimentary AI-enabled strike capabilities, which broadly but indirectly supports widespread pursuit. The first part is supported by E2, which reports a UN panel finding of a probable autonomous drone attack; the second is supported only indirectly, since E4 speaks to access rather than active programmes; and E3 indicates most drones still require human control. The report judges this closest to the mostly-true criterion.
