There is a point to be made that fewer and fewer people are ready to die - eventually.
However, it arguably is the natural course of things, and the only thing more certain than taxes. I'm not saying this because I cannot imagine a world in which death was switched off. Instead, I would argue that it is also a GOOD thing that death exists, as it makes one's lifetime more precious knowing your days are counted (it's also good not to know how many of them you have left). There is space made for new generations, and their different (hopefully eventually better) ideas.
