The Brexit circus and the unpopularity of U.S. President Donald Trump are causing apprehension about the future of the Anglosphere, the cultural, intellectual and political influence of the core English-speaking nations: Britain and the United States.
As a non-native English speaker who works in the Anglosphere, though, I'm not worried about that; Americans and Brits are merely facing increasing competition from within their accustomed domain rather than from without.
The English language, which has just 379 million native speakers, is spoken at a useful level by some 1.7 billion people, according to the British Council. That has long ensured that U.S. and U.K. voices are heard louder than any others.
