Haha I was actually on my way to become a german teacher for a while, either that or a translator as I was studying german in university. I decided though that with the rise in technology translation jobs would most likely go extinct eventually and being a teacher didn't sound as nice after having spent so many years in schools at the time. I hadn't even thought about AI at the time so maybe I made the right choice not to pursue it.
and yeah, it helps a lot being surrounded by a certain language to learn it easier.
