Yes, those are the cold facts. I probably should have put superstar in scare quotes. But the con was that she was some sort of Stanford 'superstar'.
I looked over her bio on Wikipedia. Yeah, she certainly came from a rich + connected background. So she understood rich people and what they wanted to hear. However, I don't think her Stanford professors were implicated, at least as far as I've read. They didn't knock any sense into her but they also didn't co-sign.
But none of the adults raised alarm. I got into it once with a VC trying to say that Sand Hill was blameless. That was nonsense too.
