Lagarde structures her entire speech around Homer's Odyssey, using the ten-year cycles of Odysseus's journey as a framework. After looking back ten years to the Class of 2008 who graduated into the financial crisis, and forward ten years to the Class of 2028 who will inherit whatever world the graduates build, she arrives at this pivotal charge. She tells the Class of 2018 they stand at an inflection point — their decisions in government, finance, tech, and academia will determine whether technology companies are regulated, whether inequality fractures society further, and whether climate change is confronted. The line is her call to authorship: you don't just live history, you write it.
