But that doesn't mean that the solution is to do nothing.
The solution is to higher more women and at the same time taking steps to destroy the gender roles that stop them from going into STEM fields and encouraging them to join STEM fields.
There is a very good reason for at least part of this (read the tables not the titles):

By the time we finished the degree, there were no women.
And yet tech companies are now being told that in order to bring about equality, they must hire the comparatively tiny number of women making it through these courses over similarly qualified men, simply for the sake of doing so.
In my time at university, I have never seen a female computer science major have trouble finding opportunities, even if they were miserable coders. The fact that they bring "balance and diversity" to a team apparently is already enough of a qualification for some companies.
That being said, I think the undersupply of programmers is so severe that even if this subconscious bias was corrected it wouldn't increase the supply of people enough that it would necessitate "hiring less men as a result."
