Pharrell builds to this closing formulation with the logic of a supply-and-demand argument. He acknowledges that a great education is harder and harder to come by, but reminds graduates that 'like anything in life, if there is enough demand, somebody will supply it.' The graduates' job after leaving NYU is to fuel that demand — not just by pursuing education themselves, but by being visible endorsements of what education makes possible. The two-sentence couplet — no humanity without education, no education without demand — functions as the speech's thesis statement, tying together everything he's said about service, visibility, and the responsibility of graduates to be walking proof that education matters.
