If all of the claims from Chinese tech companies and research was half as good as they claim we would all learn Mandarin by now.
That is exactly right, and simplified Chinese is actually extremely popular yo learn here now. (Denmark)
And no wonder, they have become leaders of several key (future) technologies.
Counter point: I know exactly one person who learned Mandarin and several dozen who don‘t. Pretty much everyone learned english and (to a lesser degree) a third language that isn‘t Mandarin either. French, Spanish and Japanese are popular, though.
Have you heard of a man named Elon Musk? He's the king of over promising. US company's put out just as much garbage "look we solved X" as China dude.
Classic Fediverse. Can‘t have China critique without the token whataboutism response.
They teach Mandarin in more US high schools every year
