text: A lethal autonomous weapon is a machine that locates, selects and engages human targets without human 
  supervision.[o] Widely available AI tools can be used by bad actors to develop inexpensive autonomous 
  weapons and, if produced at scale, they are potentially weapons of mass destruction.[248] Even when used 
  in conventional warfare, it is unlikely that they will be unable to reliably choose targets and could 
  potentially kill an innocent person.[248] In 2014, 30 nations (including China) supported a ban on 
  autonomous weapons under the United Nations' Convention on Certain Conventional Weapons, however 
  the United States and others disagreed.[249] By 2015, over fifty countries were reported to be researching 
  battlefield robots.[250] 
  
  AI tools make it easier for authoritarian governments to efficiently control their citizens in several ways. 
  Face and voice recognition allow widespread surveillance. Machine learning, operating this data, can 
  classify potential enemies of the state and prevent them from hiding. Recommendation systems can 
  precisely target propaganda and misinformation for maximum effect. Deepfakes and generative AI aid in 
  producing misinformation. Advanced AI can make authoritarian centralized decision making more 
  competitive than liberal and decentralized systems such as markets. It lowers the cost and difficulty of 
  digital warfare and advanced spyware.[251] All these technologies have been available since 2020 or 
  earlier—AI facial recognition systems are already being used for mass surveillance in China.[252][253]
