In the last few years, artificial intelligence has become a central focus of geopolitical competition, and especially of U.S.-Chinese rivalry. For much of that time, the United States, or at least U.S. companies, seemed to have the advantage. But Ben Buchanan, a leading scholar of technology who crafted the Biden administration’s AI strategy, worries that the United States’ AI superiority isn’t nearly as assured as many have assumed. In an essay in the November/December issue of Foreign Affairs, Buchanan, writing with Tantum Collins, warns that “the American way of developing AI is reaching its limits,” and as those limits become clear, “they will start to erode—and perhaps even end—U.S. dominance.” The essay calls for a new grand bargain between tech and the U.S. government—a bargain necessary to advancing American AI and to ensuring that it enhances, rather than undermines, U.S. national security. Dan Kurtz-Phelan spoke to Buchanan about the future of AI competition and how it could reshape not just American power but global order itself.
