Before English, German and French were the lingua franca's of the world. Then Hitler came along and fucked that up for Europe, the US took advantage and spread its defaults around the world, now Trump is here and it may be the end of that. If China's clever, they'll do more than just owning supply chains and actually try to spread their language and world view.

From the looks of it, that's one thing they haven't understood yet: you need a strong marketing and ad machine to really take over in the hearts of people. Material ownership can be reversed more quickly than cultural and mental. There are still lots of people who will continue to speak English, make English content, and spread US culture around the world long after the US hegemony falls. If China's only legacy is material and not in world-wide language and culture, it will be quickly forgotten.
