When we talk about the medium or long term, we should also start to consider the impact of life-extension, and more importantly, youth preservation technologies; the entire issue of "young supporting the old" disppears if people stop aging. There is virtually no government support for research to support this, even though we should consider it one of the most important issues in history (and many diseases simply a subset of the "disease" of aging.) Perhaps trends like the ones discussed in the article will get governments thinking about it (and having Google investing in this area is a nice boost.)
