Well educated people who can work on this problem are not minorities, i.e. they have access to education, higher social status, better starting point. While their color of skin might be different, they don't need to be aware of all the issues their race/sex faces. Example can be difference between treatment of certain minorities in US (where most of the science is developed) and the rest of the world. A scientist at Facebook/Google will develop something for the whole world having US centric view, without access to views from other cultures and their reqiurements for fairness.
