While relative immortality (i.e. no death of natural causes) holds many opportunities for positive change (such as eliminating a short-sightedness and 'repetition'[0] of history due to our individually limited perception of history with a ~70-year horizon), I can only seem to imagine a world where death can be overcome as a dystopia rather than an utopia. The same forces that drive human conflict now will still exist and I think worsen. If it's a procedure and not inherited, either it goes along with technology supplying humanity with cheap nigh-unlimited energy and thus space travel, uploading of minds or it's a two-caste world in which the same immortal persons hold the mortal masses at bay with any means necessary. If it's immortality for all (say through a virus that spreads naturally), it's a world where people have to be naturally sterile and only the priviledged get to have children, you get to wait thousands of years before you can procreate due to a place being free because of accidental deaths or no one gets to have children (but a governing body through technical means, arifical wombs). Also, I can imagine relative immortality would render global nuclear war an inconvenience, with proper protection you could maybe wait out the aftermath and start again?
