Guest: Bonnie Hammer, former Vice Chair, NBCUniversal
Timestamp: 03:56

• Understanding these patterns can shape prevention strategies and reduce catastrophic damage.

4. Technology, Screens, and Human Connection

Guest: Christine Rosen, senior fellow, AEI
Timestamp: 08:11

• We're spending less time together in person; technology mediates more of our relationships.

8. Polarization in America—A View from Abroad

Guest: Zanny Minton Beddoes, Editor-in-Chief, The Economist

12. The New Era in Medicine: AI and Genetic Data

Guest: Dr. David Agus, Professor of Medicine, USC

Guest: Thomas Chatterton Williams, writer
Timestamp: 30:40
