The interview she gave with NBC says she's a college student studying languages, so if nothing else, she could have a good life as a translator. And you don't generally study languages plural in college if you're not very smart.
She's Elon's kid, and she had to suffer through being trans in a society that doesn't broadly accept it (and at least one parent who doesn't), so she's got a lot going against her, but she sure seems to speak out with self confidence, so I hope she's one of those who was able to just grow from the hardships.
