The parent I was responding to suggested that he might have openings at his company for which there aren't any "good" (or even any at all) female applicants. I find it absurd to suggest that there are zero qualified women existing in the world, so the problem is one of finding and recruiting them to apply.
EDIT: My mistake, that was a different user.
Making the effort to consider qualified women is part of actively working towards it.
Maybe it does cost some small amount of extra money, but if you refuse to make even the minor effort of, say, posting to a women's tech board[0] then you are part of the problem.

We should work towards being more fair individuals and looking at both genders with the same criteria in mind, gender aside while also tapping into female development resources like the one you mentioned.
I also believe we should introduce tech at an earlier age, say in high school, because right now tech is grossly misrepresented versus the other sciences which women have no problem going into.
