Ok, but how do you do that? It was easy in classical music; they just started doing auditions behind a curtain, without any verbal Q&A, and suddenly a field that used to be dominated by men became pretty much 50/50, and all the people who said that men were better at the highest echelons of musical achievement had to shut up.
But tech companies want to talk to the humans they're hiring, so race and gender are (almost) always available as information inputs during the hiring process. There's no equivalent to the curtain to remove the possibility of bias, so you need to look at alternate methods. Setting hiring targets is one way to do it. If you're going to complain that the targets are unfair, you can't just say "Well shucks, guess we have to stick with the system that produces massively unequal outcomes." You've gotta propose a system that's less unfair than the status quo.
