Even before robots take all the jobs, we will see massive disruptions.
Agriculture in developing countries notoriously inefficient. Tiny plots of land, supporting more people than are needed to cultivate it. The land degrades, and will need modern techniques to rehabilitate it. This will entail rationalisation (to be able to afford the machinery and inputs), and many farmers will be pushed off the land, at a time when jobs in city factories are also being replaced by robots.
Implications of the Bell Curve: The combined population of India and China is 2.6 billion. The top 5%, in cognitive terms, is 130 million. China and India are producing at least twice as many smart, educated people as they can employ domestically. At the moment, they are constrained by lack of fluency in English. But in a few years this will not be an issue as Google and others perfect real time language translation. These people will be competing for jobs everywhere in the world.
