Clearly, English is an inferior language :-)
And now we have once again two competing languages dominating the world stage, american English in the west and Chinese (or Mandarin I guess) in the east.
I can't imagine a future when these merge naturally, because they don't have any common ground to speak of.
However, realistically speaking... If we actually do manage to become a singular community, one language would win at some point. I doubt it'll happen while we're alive, but it'll surely be an interesting topic for historians of the future... As long as we survive long enough I guess
Surely Mandarin is not making much leeway into India, Korea, Japan, or most other countries in the east.
If not, I didn't claim it either.
But you already made up your mind in misinterpreting my message so I'll desist.
As far as merging, Mandarin borrows phonetically sometimes but isn't nearly as eager as Japanese, which has found quite a bit of loanword usage. Which is to say, I think it's possible.
English is my second language. At first I found English quite easy: non-gendered nouns, simpler tenses, etc. But, after 25 years of using it it still shocks me at times. If you see a word for the first time you can have a guess how to pronounce it, but you could never be certain without consulting a dictionary.
