Because if your older your going to die sooner and so these things you talk about are less likely to happen anytime soon and perhaps long after your dead.
What I basically believe in doing is creating an alternative society parallel to this one as it decays.
Nurture it, keep it small. Make it so it can survive anything. When this one starts collapsing the other one
goes into the ascendancy, outreproducing the dieing, warring masses of this civilization even under adverse conditions.
So why care that much about making an alternative society to survive this one whats the grand and noble purpose of it anyway?
