We are currently witnessing an unprecedented proliferation of emerging disruptive technologies (EDTs) in the cyber-physical battlefield. This is coupled by the increased weaponization of civil commercial technologies and the prioritization of high-tech solutions to mitigate international security and defence challenges. Game-changing technological advancements in fields ranging from artificial intelligence (AI) systems to big data, additive manufacturing to autonomous robotics, quantum-enabled to cyber defence technologies, have important dual-use and civil-military applications and are expected to radically transform warfare, human security, and human-machine relations. Great Powers such as the United States and China, as well as commercial technological giants, are currently engaged in an evolving (arms) ‘race’ to harness their strategic and economic potential. The Course contributes to the understanding of the technology-security research nexus, special consideration being given to the impact of high-tech-powered and mediated security and defence practices. This Course will highlight various interconnections between technology, power, human agency, and security, as triggered by new and emerging technologies. By focusing on historical and theoretical insights at the intersection of International Relations, (Critical) Security Studies, and Science and Technology Studies, as well as concrete empirical examples, the Course provides a critical overview of integrating various security and defence technologies in contemporary warfare. The course will also engage with broader ethical, (geo)political, normative, and governance concerns related to the use of such technologies in the conflict management cycle.
