Are these the future of modern warfare and how concerned should we be? There are efforts to limit the development of these weapons. More than 50 nations met at the UN in Geneva this month to discuss a possible treaty. But neither Russia nor the United States have expressed any willingness to support the treaty. Ed Butler speaks to Professor Noel Sharkey who's been campaigning against the development of these weapons for 14 years and asked him how close any type of agreement was. Evanna Hu, CEO of AI firm, Omelas, and a senior fellow at the Atlantic Council in Washington, says this technology is now at the forefront of many countries' weapons development. And George Rey is a retired Lieutenant Commander in the US navy. He now works with private sector defence contractors supporting the development of autonomous weapons systems for the department of defence.(Picture credit: CARL COURT/AFP via Getty Images)
