My time to shine.

First of all we're seeing a decline in human population so don't worry about overpopulation when 2080-2100 kicks in.

The resources argument is good, but the real problem is the way we distrubute them, not how we consume. Sure it needs the change in global economy politics, now we're in agressive capitalism but its doable.

Sure, some people work at really awful places, but robotics and automation will absolutly change the labour, first in developed countries then in second and third world ones.

The fixing od aging also gives you a very important thing about place to live. You can't spoil the planet you live on right? And if you live for 500 or 1000 years better start caring for it.

Personally the endless experiences that fixing aging gives us have most meaning for me. Even these bad ones or problems you need to deal with. As long as you're alive you can do it, when you're dead well, nothing is possible anymore.
