The progress of medicine and biology offers us longevity and deludes us with the promise of immortality, thus rekindling an ancient dream. After illustrating how death is confronted, or not confronted, today, we analyze the perspectives offered by post–human technologies in view of immortality: hybridization with machines, transfer of the mind in computer progammes, merging or substitution of the human intelligence with the artificial intelligence. This is a surrogate and dislocated immortality, that favours the cognitive aspects and tends to neglect the ethical and social ones.
