"So I think the way to think about it isn't whether it's going to help or not, or does it do something well or not, but does it do it better than what we're doing today? And I think that gets to deepest point of values. If we take a problem and we solve it and now it's 90% correct, well what does that mean? Do we only care about overall correctness, or do we care about how does it have disparate impact on different types of people? If it's 10% wrong, is it 10% wrong on everybody"
