What does a Nobel Prize-winning economist think about AI, research, and rational expectations? Professor Thomas J. Sargent, a 2011 Nobel Laureate in Economics, joined PHBS students for a lively roundtable at the “Dialogue with a Nobel Laureate” tea talk. During the conversation, students raised questions spanning AI in research, career planning, innovation, US-China relations, and the PhD journey. Professor Sargent shared his insights: AI should complement our thinking instead of replacing it. The true value of AI lies in helping us deepen our grasp of fundamental principles, rather than simply generating outputs. He also explained how rational expectations theory evolves alongside AI, and reminded young researchers to focus on timeless core principles, not just trendy topics.
