Many don't realize or acknowledge the existence of these barriers, because they are not affected by them. When you have the wind at your back you tend to attribute your success to yourself.
This is the first time it's gotten any comments.
I'll guess the non-interest is due to some combination of HNer's being unaware, uninterested, and resigned. And a lot of folks just not wanting to go near a topic that often gets loud & divisive, but seldom seems to inspire any insight or progress.
I think most people here would accept that black people in America are systematically disenfranchised. But the entire onus of the article is on the failure stemming from within academia. This isn't an academic discussion board, and I never attended a computer science program so I can't speak to that either.
And again, the data they presented showed how overrepresented other minorities are within the programming profession. So it doesn't seem fair call the entire profession racist when it seems like the specific problem is that black Americans are disenfranchised across all spectrums of their life.
