Out of curiosity: has anyone ever tried to do a correlation about the performance of a hard-tech company vs the ratio of technical/political people in their board of directors? This is probably a strong prior on my part - but when I saw the composition of the board of directors of Theranos (secretary of states/generals/congressmen etc) I was immediately incredibly skeptical. It seems like the board was chosen to provide lucrative contacts instead of actually useful advice and supervision.
