I could see living longer and healthier being a benefit, but infinite life span could retard human development in some ways. To me, the old dying out is often how the zeitgeist changes in a culture. Most people I know above 50 are deeply entrenched in their beliefs and struggle to understand new ways of thinking. It is an interesting question how much immortality or even living to 500 would change the way we perceive ourselves. If anyone has dealt with the generation gap of say a grand parent who comes across as racist or xenophobic, just imagine how odd it would be to talk to ancestors 10 generations removed one way or the other.
I would say not sure humanity is ready for such an advancement yet given our often short sighted views. Maybe others are more optimistic and think if you had to actually worry about 2200 you would live differently and utilize resources and spending habits accordingly.
