Is it worth living for more than a hundred years? Will artificial intelligence be used to prolong human life and aspire to immortality? - Today, artificial intelligence and new technologies are rapidly changing our daily lives, how we relate to each other, and our rituals, symbols, and expectations. It has provoked great interest and a cross-impact of societal enthusiasm and fear. - With exceptional clarity and lucidity, the novel THE BRIEF, with suspense, tension, and unexpected twists and turns, addresses a crucial and borderline concern that many readers question: the tantalizing pretension of using artificial intelligence and biotechnology to prolong human life and delay the arrival of death as long as possible. It invites the reader to reflect on a profound and defining theme of human beings: their finitude. - The plot deals with the emotional journey of the protagonist, Pedro Romero. His psychological arc through the experience of living as a refugee with his parents on Icaria, a Greek island, during the Tragic Decade and the Absurd War; the three decades of research on how to delay cellular aging; the death of his wife for having applied the first version of his Youth Injection; his parents' trip to Antarctica; his ambition to have the formula for eternal youth to win the Vanguard Award in Biomedicine; the commercial dispute of the regional blocks to control his discovery; the harassment and accusations of corruption and murder of his wife by prosecutor Leo Soto; the trial and sentence of a robotic judge with artificial intelligence; the rejection of his daughter; the platonic love of his assistant Lila; his seclusion and the gradual acceptance that the Youth Injection he discovered is limited because there are a thousand ways to die and that life is finally beautiful, but fleeting.
