As a POC, it bothers me that someone from the "corporate(or educated) class" of POCs always coming in to criticize those POC who have a legitimate concern about some injustice they are seeing. In this case Timmits concern is entirely valid and does not have a solution currently other than do not use ML for some applications. We benefit from Timmit and others voicing these valid concerns. Engineers always want to base everything on the data to take themselves out of what is being asked of them. It is not always possible to reduce problems to "the data". POC in particular should not be quiet when it comes to some of the issues around the questionable use of ML in relation to race and issues that are ultimately surrounding race.
