I think you're missing the point, which is not calling you racist, but opening your eyes to the fact that much of what you have achieved (and I don't mean you specifically, but the class of people the article adresses) is not a direct result of your effort but largely due to privilege. Thus, as a person of privilege you should use whatever political power you have - and you have quite a lot of it - to help rectify the situation, or, at least be constantly aware of it.
Merit does not require effort. I haven't heard anyone claiming that their ability to program is a measure of their worth as a human being. It is, however, a measure of one's usefulness to a development team.
Ok, but isn't it in the interest of all software employers to use their political power to create more capable developers? This is simple economics; I'm not even touching ethics or justice here. And isn't it the immediate interest of current developers to maintain their value by blocking others from entering this profession? Sometimes we adhere to hidden interests without even realizing. Let us first open our eyes to how society works and how we may, inadvertantly, keep others down.
