"In the name of diversity, when we fill quotas to check boxes, we fuck it up for the genuinely amazing women in tech." Awesome. A plea towards hiring based on quality, rather than quotas. Towards a group that is judged by the content and quality of their character rather than some of the variation of an attempt to combat discrimination through discrimination.
So quotas are terrible, yes. But what if there are still biases in hiring? That someone sees a woman and assumes this or that about her based on gender alone?
