On 14th March, the Stockholm International Peace Research Institute published a report: Bio Plus X: Arms Control and the Convergence of Biology and Emerging Technologies, saying that advances in additive manufacturing, artificial intelligence and robotics could increase the possibilities for the development, production and use of biological weapons. The existing biological arms control and non-proliferation governance framework needs to be adapted to address these security risks. The report explores the risks and challenges posed by the interaction of developments in biotechnology and advances in 3 emerging technologies: additive manufacturing (3D printing), artificial intelligence and robotics. It says that all 3 technologies are difficult to control, particularly due to their digitisation and their dual-use nature. National governments need to monitor and assess developments in science and technology on a more systematic basis.
