I tend to agree. From what I've read about her (and not in the puff-pieces at the height of the Theranos hype) she was indeed a much smarter than average young lady - but probably the team was not able to deliver on the original vision/ idea, and rather than admit defeat, they tried to cling on it for as long as possible.
No doubt she is a bright well-educated driven person. Zuckerberg-esque, no doubt. But zuck pulled it off because Facebook didn't need any next-gen tech to launch and get big-- just elbow grease and investment/marketing connections. You can't wing it to launch a new blood diagnostics.
