I remember at the time so many experts I knew in the field would say the Theranos claims were total BS and what she speaks of was tried and doesn’t work for X, Y, and Z reason. A science company board full of people without a science background was also a giant red flag. There were very much some she wasn’t fooling, but the broader media-sphere, PR engine, and high profile folks without a technical background bought the whole thing hook, like and sinker.

In that way it was a textbook con. Avoid those that would sniff you out and focus on those that will be gullible to your play.
