If you want to hear the opinions of younger Taiwanese people this is probably not the place, this forum is mostly populated by middle aged westerners. The only poster that I know of that might fit into this demographic is @Gain, and it’s not really a discussion if there’s only one person stating their opinion.
I know a handful of young Taiwanese who work in factories in southern Taiwan who prefer Hokkien.
Edit: I just noticed you asked “ONLY Hokkien”. Obviously not. How is it even possible to only communicate in Hokkien? Lots of people don’t understand it (including me).
Really depends here, don’t discredit hokkien/taiwanese. The southern u go, the more local u get. Have a few under 30 friends of my wife from the south who mostly speak taiwanese/hokkien among themselves, they r all uni graduates and not from the countryside
Taiwanese is already taught in school. It was mandatory for many years, but I believe now the options are Taiwanese, Vietnamese, Indonesian, and a couple of other SE Asian languages.
Students are encouraged to pick the one that is spoken in their home.
It’s not actually assessed on the report card though, right, so I am guessing that quality varies dramatically. My kid has been in the class for years and asking him now he can’t say a single word, not even Hello.
