Emerging technologies such as artificial intelligence, machine learning and the Internet of Things are shaping every aspect of modern society, including national security. The current pace of technological change, especially in the form of emerging and disruptive technologies, is unprecedented. The geotechnological revolution is fuelling global competition, in particular the great power rivalry between the United States and China. Areas of competition include cloud technologies, semiconductor chip technology, hypersonic and new missile technologies, and space-based applications. Canada and other industrialized nations are incorporating many of these new technologies into their national security strategy. As this decade unfolds, AI is expected to transform modern warfare through advances in military technologies, fuelling a global arms race that will redefine the way Canada defends itself.
