After watching Project Hail Mary, Cal sees more than a sci-fi story about saving the stars—he sees a blueprint for how humans might survive the age of AI. That insight leads him to a real-life story even more extraordinary. When tech founder Sid Sijbrandij is diagnosed with a rare, aggressive cancer, the traditional medical system eventually runs out of answers. Most people would accept that outcome. Sid does the opposite. He treats his own disease like an open- source problem—gathering data, building a team, and chasing solutions across the globe with the same mindset that helped build GitLab into a billion-dollar company. With the help of AI, Cal translates this complex scientific journey into a human story anyone can follow. One that's filled with pancakes, partnerships, love, and a radical idea: What if the future of survival—against disease, against uncertainty, against AI itself—belongs to those who adapt fastest? This episode is about more than cancer. It's about how humans fight back.
