The most important question in the world right now is: which generation will be the first to live indefinitely? It is clear to me that we are on a trajectory to achieve indefinite lifespan extension, but unlike Kurzweil et al I don't see a real possibility that it will happen soon enough for me personally. Maybe my kids, or maybe one or two generations further. Will it happen soon enough to prevent population collapse due to plummeting fertility rates? Will fertility rates go even lower or will the population start to rise again as deaths fall? Will we see stagnation due to older brains being stuck in their ways, or will we be able to fix that too?
