In Milan Kundera's "Immortality," the protagonist grapples with the concept of usefulness in society. He questions the true meaning of being useful, reflecting on how the contributions of people throughout history shape the world as it is today. This introspection leads him to a profound realization.

He concludes that perhaps the pinnacle of morality lies in embracing a sense of uselessness. By suggesting that the ultimate value may reside in not being bound by utility, Kundera challenges the conventional belief that one's worth is solely based on their contributions to society, opening up a dialogue about the deeper significance of existence beyond practical measures.
