I’d just like to point out that no Lingua Franca has lasted forever. It was French before English, till post WW2. Also this doesn’t matter as much, but, English is one of the more difficult languages (compared to Spanish say) due to all of its spelling inconsistencies and large phonetic possibilities. I don’t know if a tonal, character based language will be any easier though. I say it doesn’t matter because it doesn’t seem to be the difficulty of learning the language that matters, only the strength of the language in terms of economic opportunities.
