Without death we cannot truly have life. As such, what a travesty of life it would be to achieve a machine-like immortality!
Gray writes the following chilling lines: “If you understand that in wanting to live for ever you are trying to preserve a lifeless image of yourself, you may not want to be resurrected or to survive in a post-mortem paradise. What could be more deadly than being unable to die?” (my emphasis)
Sounds like sour grapes. I'd heard of people holding such sentiments; this is the first time I've actually seen them expressed myself.
