AI is advancing so quickly that companies can’t afford to treat it as simply another productivity tool; it is fundamentally reshaping strategy. In this final episode of our special four-part series on how AI is changing leadership, Wharton professor and AI expert Ethan Mollick explains why leaders need to rethink what their organizations are designed to do—and how work gets done. He discusses how AI agents are changing the role of managers, why companies need to experiment rather than wait for proven playbooks, and how leaders can create competitive advantage when everyone has access to the same frontier models. Mollick is author of the forthcoming book Co-Existence: The Next Phase of AI.Plus:• Why AI-driven productivity gains can disappear if companies don’t change their processes and incentives• The four capabilities that will become increasingly valuable: deep knowledge, wide knowledge, taste, and agency• Why companies should build for what AI will be capable of, not just what it can do todayIn case you missed it, you can find the rest of our AI series below.How AI Is Changing Innovation: Why Speed Alone Isn’t a Strategy: https://hbr.org/podcast/2026/10/how-ai-is-changing-innovation-why-speed-alone-isnt-a-strategyHow AI Is Changing Communication: Weighing Efficiency with Efficacy: https://hbr.org/podcast/2026/09/how-ai-is-changing-communication-weighing-efficiency-with-efficacyHow AI Is Changing Talent, Not Just Tasks: Rethinking Where Human Judgment Matters Most: https://hbr.org/podcast/2026/09/how-ai-is-changing-talent-not-just-tasks-rethinking-where-human-judgment-matters-most
