Apple isn't exactly a portrait for employee diversity
You could say that about the whole technology industry in general... When you look at the tech industry it is pretty much white and asian guys and it goes all the way to the education. There's no bias in the university selection process and despite this were not even making progress in this area.
In the 80's as many as 37% of those receiving an undergraduate degree Computer Science in the U.S were women, but these days that number is down to 18% (14% for the better universities). Mind you, Computer Science is the computer related field with the highest female representation, women are even more rare in fields like Electrical, Software and Computer Engineering (which is what I'm majoring at).
I don't think any sane person can from this draw a conclusion other than that women and (other) minorities simply aren't as interested in this field and the inevitable end result is what you see today. Just look at Liberal Arts fields, those are the same thing except in reverse, so women are getting into higher education, it's just that they're not going into the same fields as men and somehow them being overrepresented isn't an issue.
The only way you're going to see any short term change is by giving women and (other) minorities an unfair competing advantage, but that's just idiotic and goes against the basic idea of equality. You simply can't have half-and-half without some serious favoritism when the other group that's supposed to represent half is less than a fifth of the workforce.
Despite being white and male (apparently the worst combination today according to some) I'm not against minorities and women in technology. I've worked with both and never had any issues with the people I've worked because of gender or ethnicity. However what I am against is trying to boost their percentage by giving them an unfair competing edge and filling companies with employees other than the best ones they can find.
However I guess it's probably going to be inevitable that we're going to see women and minorities getting an edge over equally qualified people who don't fall into those categories. One thing modern day feminists have already taken as their target is a concept called a "Meritocracy". What does it mean? It means that people are judged by their merits, i.e their skills and experience, not their gender, age, ethnicity or sexual orientation.
Sounds like something feminists would line up to get behind right? Well apparently not. The idea of a meritocracy used to be something social programming platform GitHub believed in so much that the carpet in their faux oval office read "In Meritocracy We Trust" (as in a play on "In God We Trust"). Then feminists started rallying around the idea of equality being a bad thing because women somehow can't be expected to put in the same amount of work and to silence them they actually had to remove the carpet. The new one reads something like "In Cooperation We Trust" if I recall right.
