More info in this article: "The system, he argued, is still more objective than the flawed metrics used by human recruiters, whose thinking he called the “ultimate black box.”" I guess if we compare humans vs. machine its ok to have black box? https://www.washingtonpost.com/technology/2019/10/22/ai-hiring-face-scanning-algorithm-increasingly-decides-whether-you-deserve-job/

I don't like it when humans don't provide explanations for decisions. I'm definitely not going to accept it from a black box algorithm.
