Artificial Intelligence (AI) is changing the international balance of power. In the field of defence, beyond weaponry, AI is instrumental for various Intelligence, Surveillance and Reconnaissance (ISR) tasks at the strategic, operational and tactical level, as well as automated reasoning, logistics, training, and much more. In this episode of The Sound of Economics, Giuseppe Porcaro invites Sarah Shoker to discuss the evolving role of AI in defence.  They highlight AI's role in foreign policy decision-making and prediction, but stress that balanced human judgment is crucial due to AI's limitations. Speakers urge caution in AI integration, complementing, not replacing, human reasoning. International cooperation for responsible AI norms and regulations is also needed.
