Back in 1963, I was tutored in calculus by a 15-year old who won that year's Science Talent Search for his research in nuclear magnetic resonance. He had completed essentially all of undergrad math and physics. I think you have a badly warped view of what is possible for smart people, whatever age.
No, I think there's a reason she recruited a professor in that industry who had well over 30 years of experience.
That doesn't detract from her intelligence, but I think it's safe to say she would have simply done it herself if she could have.
I think simply describing her as an "idea person" is also missing the mark, but so are you. She isn't a magician, she's just a person.
And considering she was 19 and in a normal college curriculum, it's very likely her talent is not in being super smart, but in being able to come at a problem sideways.
