> Surely you would agree that hiring a white American as a waiter in a Chinese restaurant where only Mandarin is spoken by the kitchen staff (not uncommon) would hinder the effectiveness of the restaurant?
This isn't the position though. This is adding additional hypotheticals like language barriers. It would be more like hiring a white american waiter of a chinese restaurant, where both the white american waiter and the chinese kitchen staff don't have significant language barriers. In that case it might actually be helpful depending on the demographics of people eating at the restaurant.
Culture and language are inexorably intertwined. Just ask anyone who has tried to learn a foreign language. A cultural barrier is just a softer communication barrier, where language has to be much more formal than speakers are typically accustomed to, in order to be understood and not to offend.
When I'm speaking to people whom I relate to well (including colleagues), half of it is movie quotes, rude jokes, varyingly subtle digs, etc. I suspect most people are the same. In order to write for a wider audience, I have to add rather a few more layers of thought and consideration to what naturally comes to me - to formalize my language.
This burden of formalization is in fact exactly what Google is trying to help with. It is only required when people don't relate to each other well. Having a homogeneous team eliminates the problem.
