Anglo speakers! cool down
After many decades of sovereign in every kind of world-wide communications, the use of English is turning in to a needless enforce. Countries like China, India or Brazil are working hard to take the place of the first economical potency on the world, USA. And it looks like they are going to make it.
For example, the economic dominance of OECD countries (which has helped circulate English in the new market economies of the world) is being eroded as Asian economies grow and become the source, rather than the recipient, of cultural and economic flows. Population statistics suggest that the populations of the rich countries are aging and that in the coming decades young adults with disposable income will be found in Asia and Latin America rather than in the US and Europe. Educational trends in many countries suggest that languages other than English are already providing significant competition in school curricula.
The future for English will be a complex and plural one. The language will grow in usage and variety, yet simultaneously diminish in relative global importance. We may find the hegemony of English replaced by an oligarchy of languages, including Spanish and Chinese. To put it in economic terms, the size of the global market for the English language may increase in absolute terms, but its market share will probably fall.
