I think she is indeed very bright, but sadly many jobs today, and nearly all high paying positions, require some qualification. It's so impressive that she has been able to get to that level of Spanish, especially from teaching herself. But if she ever wants a job in that field, then she'll struggle. In areas such as translation work etc., they are not going to hire someone based off that person saying "I am fluent in Spanish." They don't care if you don't have any qualifications to back your claim up. She would struggle a lot trying to get a job in the language field. Even to work in McDonald's you need GCSEs. It seems that her career goal is to just be a youtuber. I'm not really sure how long that will last. It's certainly not enough to sustain her for the rest of her working life.
