I think it is true that there is a diversity problem in SV, just like there is a diversity problem in medicine. It’s a problem, because there is no a priori reason for women and ethnic minorities to be less prevalent in our high-paying fields. But that’s probably the only point that resonates.
The criticism of Juicero and Theranos being emblematic of focusing on the wrong problems is not sensible. Companies fail, sometimes spectacularly, sometimes due to dishonest behavior, etc. If Theranos had the tech they claimed to have, it would have been richly rewarded (outshined only by the consumer surplus it would have created).
The oddest turn is that of blaming the global rise in income inequality on SV, and then to lambaste SV for trying to come up with solutions to ameliorate that problem as it proceeds to its logical extreme.
