"The language of the National Designated Other is bound to switch to Chinese in a couple of years" I assume this in reference to the predominant 2nd language for most people? If so, something I've always struggled to agree with is the implication that English is the second language for so many people only because of some fortuitous timing on the part of the British Empire. Technological advancements have certainly helped, as has the fact that as the British fell from their peak the US (also English speaking) came to take it's place. But is it really just a matter of timing within a generation or two most people will be expected to be somewhat fluent in Mandarin? Maybe I'm a bit naive because I was raised speaking English, in an English speaking country, and only fumble my way through a couple of other languages enough to not get entirely lost as travelling. And I can understand the reasons why English can be so difficult for foreigners to learn because, even moving to the UK I discovered entirely new ways to pronounce words I thought I already knew. But... and I think it's a big "but"... something that has always seemed almost unique to English in my limited experience is that you can speak it badly and still be understood. You can speak it really badly, and while people might chuckle at the way you've turned a phrase you'll still get help. When I compare that to my experiences throughout south-east Asia, Italy, France, and Spain nothing further could be from the truth. Inflections or emphasis on the wrong syllable can have drastically different meanings that elicit confused looks or something altogether wrong. I just don't see Mandarin doing the same. But maybe I discount the importance of the economy as a driving factor too much.
