I am guessing that everyone who reads this blog subscribes to the idea of living past 100. Well, if/when we succeed, things will be changing.

Population aging is likely to boost medicine, nanotechnology and robotics, but increase political risks, according to the National Research University Higher School of Economics.

The UN estimates that the number of people aged 65 and older will have reached almost a billion by 2030. The proportion of those aged over 80 will grow at particularly high rates, and their numbers are expected to reach 200 million by 2030 and triple that forty years later.

Due to a combination of an aging population and declining birthrates, the demographic structure of most countries will change towards lower proportions of children and young people. As a result, the global division will no longer be between first- and third-world nations, but between old and young ones.
