Yet you're arguing that people should hurry up and die so 'we' can move on and not stay 'mired in the past' and 'wasting time'. What do they matter? Where are we moving to that's so important?
If we can live until we choose to die or die by accident, feed everyone, keep the planet in good condition, hit virtually 100% nanomechanical recycling / construction and have enough resources for people or virtual people to set off exploring the universe, what else matters? Why do we need everyone to be young? And we might be able to step usefully close to those things in a thousand years or so - and if you agree with Kurzweil, 1000 years of progress will happen in much less than 1000 years. We might even live to see it.
