Train tracks. Split decisions. And a philosophy humdinger worth debating. Dr. Joshua Greene is a Harvard Psychology professor, neuroscientist, and *actual* Trolleyologist. The moral humdinger that has been used in everything from Supreme Court decisions to board games looks at: What makes you a good person? How do you reason with people who make you scream into a jar like Yosemite Sam? How far would you go to save others? Which charities should get your money? What is active versus passive harm? And what would a monk do? Also: how neurodivergence influences moral decisions, religion used as a moral compass, and your new favorite skeleton on the planet.

We chat about the disappointing launch and critical reception of GPT-5 and what this massive claims-reality gap tells us about how an overactive industry, propelled by grand social forces of capital accumulation, are ultimately producing “normal” or “mid” technologies. Plus, we get into the productivity paradox that plagues AI. ••• Does AI really boost productivity at work?
