The battle's already been lost. Mandarin might well be the most widely-spoken language on Earth (mostly thanks to simply the size of the Chinese population), but it's going to take more than that to topple English as the language of science (and aviation). I'll be the first to admit that there's no logic as to "Why English?": it's just a combination of Empire, America, pidgin English (plus some linguistic things about the ease/lack of conjugation, genders and declensions).
The place to promote niche languages isn't going to be through science. There are far better vectors. It is a worthwhile cause.
I thought that the mantra is that language is fluid and changes?
I can see the world becoming bilingual (English and Mandarin) in my lifetime. If I live as long as I hope.
