The general scam of unrealistic promises then under-delivering is such a well worn trope that while gender surely played a part in it (as it is a big part of social perceptions in general) I hesitate to blame it here. I think for anyone who has been in tech for a while it doesn't take an imagination to picture a man doing pretty much the same thing
Yeah, the same is maybe more obvious outside of HN, but engineer/tech companies often play the same trope but on "brilliant and smart people but bit naive/rose-tinted views that couldn't unintentionally harm anyone even if they tried", like how media showcased Zuckerberg initially, before everyone realized his true colors.
I mean, plenty of men have done the same thing. No imagination required.
Gender etc provided a new vector.
The lack of awareness was the prof not realising corporate and upper class women are just as capable of being con artists with a dysfunctional grasp on reality as men are. (Other women are too, but they don't get the opportunities.)
It's an ironically sexist assumption.
Although at the same time men are less likely to face consequences - unless they defraud big-ticket investors without prior permission. Which was the true crime here, and the only one that matters at these levels.
