From a cynical point of view, the biggest problem with life extension is that you usually end up extending the worst years of life rather than the best. The article somewhat covers this, but if anti aging treatments only manage to keep people alive who are barely functional, you've actually made things worse for society as a whole instead of better. We need ways to extend productive years of life and potentially keep people in the workforce (or at least the socially contributing force) longer. I'm hopeful for some of the treatments mentioned, but I think a lot of them are going to fall into the "we managed to keep people in a hospital bed for an extra year" category. On a side note - has anyone heard anything from Calico recently? I seem to remember a lot of hopeful statements when they started up years ago with the intent of doing a lot of the research mentioned in this article, and then they went silent.
