I'm learning a language and I'm supposed to start a new level today. The school's kind of chaotic, so they just sent the link for the virtual classes today along with the name of the teacher. Googled them and found out they're a) not native speakers of the target language and b) they learned it in their 20s, so when science tells us we can no longer learn a language to a native level.
Even if this person were the exception, they're still not native to the country. So the cultural aspect, no matter how much they love this language/culture, is also not the same. Language is more than just grammar and vocabulary.
It's annoying me that the school is trying to pull this kind of switcheroo, with zero transparency to boot. I'm paying good money for allegedly native speaking teachers.
