Without echoing the other responses to your comment, I must add that I think "solving" death is just another technological milestone, just like interstellar travel, required for any intelligent species in this Universe that wishes to make its mark beyond its home planet.
One of the things that are necessary to attain the next level of civilization, or perish. Yes, achieving a post-scarcity industry/economy is also necessary, and goes hand-in-hand with sustainable immortality.
At a certain scale, those that don't have these technologies may be seen as primitive.
I suppose there'll some kinds of biologies where immortality won't be necessary, like a insect-like hive-mind species, where each member is more or less already a copy of each other, but in species that have concepts of individuality and value them, achieving immortality is inevitable.
