Advantages of such weapons were discussed in a New York Times article published last year, which stated that speed and precision of the novel weapons could not be matched by humans. The official stance of the United States on such weapons, was discussed at the Convention on Certain Conventional Weapons (CCW) Informal Meeting of Experts on Lethal Autonomous Weapons Systems held in 2016 in Geneva, where the U.S. said that "appropriate levels" of human approval was necessary for any engagement of autonomous weapons that involved lethal force. In 2015, numerous scientists and experts signed an open letter that warned that developing such intelligent weapons could set off a global arms race. A similar letter, urging the United Nations to ban killer robots or lethal autonomous weapons, was signed by world's top artificial intelligence (AI) and robotics companies in the International Joint Conference on Artificial Intelligence (IJCAI) held in Melbourne in August.
A coordinated international coalition of non-governmental organizations dedicated to bringing about a preemptive ban of fully autonomous weaponry -- The Campaign to Stop Killer Robots -- was started in April 2013. A breakthrough was reached in 2016 when the fifth review conference of the United Nations Convention on Conventional Weapons (CCW) saw countries hold formal talks to expand their deliberations on fully autonomous weapons. The conference also saw the establishment of a Group of Governmental Experts (GGE) chaired by India's ambassador to the U.N., Amandeep Gill. According to Human Rights Watch, over a dozen countries are developing autonomous weapon systems.
