It is not at all dystopian which puts it out-of-style but it paints an interesting picture of a far-future where the population has settled and immortality is essentially the norm. I recommend picking it up as a quick short read.
Personally I find myself being more cynical about these kinds of things because I think all reality this will not be a good thing in the near future for all but a very small set of people who will (without changes to the system) be able to maintain wealth and control for generations and further imbalance our already imbalanced world.
My real hope is that this increased understanding can lead to increased quality of life for all people if not widespread immortality, but given our ability to disregard the suffering of other people already it seems unlikely. Those of us living in the first world will probably continue to lead longer, more comfortable lives at the expense of or disregarding that of the rest of the world.
