I believe the world is more biased towards men and against women because women are capable of creating offspring and so if they have children they will have to take breaks periodically to take care of and raise it. Whereas the father won't have to stay at home and is able to go to work. Google and other enormous companies don't have the time for their women employees to take "vacations" in order to nurse their child so they will hire the father, or the man, because he usually does not need to take breaks as extended as a woman's. This doesn't mean that every woman has a baby, but the companies will just assume that because this woman is young and a woman that she will have a baby, but it doesn't apply to everyone.
In the article, it is explaining how Google is trying to create a more diverse community within the company, although they don't have any evidence of them making an effort. The article is focusing on Google specifically choosing the majority of the male gender, but what if the majority gender of employees at Google are males because more men were intrigued by the subject of technology than women. The article doesn't really explain this topic because it is not a major contributor of the bias.
I believe everybody in the world contains bias in them. There will always be bias in the world as long as people have opinions for things. The issue with Google, i'm not sure how they will "solve" their issue of no/low diversity, I believe they will at least improve the diversity, but it might be impossible for Google to be symmetrically diverse between men and women.
