If you want to see if this is likely to happen, look at recent developments in the military. That is a place, if anywhere, where we would say that we should get the people most qualified for the job without worrying about gender. And indeed most people will say that standards should not be lowered to allow women into the military. Even people who support female soldiers will generally do so only on the condition that they meet the same grueling standards as men.
But what happens in practice? When the standards
are uniformly applied, very few women at all are able to meet them. If people were honest in being able to ignore gender in the decision, that would be the end of it. We allow women only if they meet the grueling standards most didn't, so there aren't many female soldiers.
Instead while the standards were previously held up as fair and essential, they are now criticized as unfair precisely because few women meet them. It is said that if men can do something better than women, on average, and the standards require those skills, then the standards aren't really anything important and are only there to weed out women. Nevermind that these were the very same standards previously thought to be essential, now they must be eliminated in the interest of having more female soldiers. The talk of women meeting the same grueling standards was nothing more than a polite fiction that nobody really took seriously in the first place.
You can see how thick the double talk is by looking at
reports on current changes to standards. (A nice drinking game for that article is to take a shot every time the article directly contradicts itself, such as by saying that the changes aren't about accommodating women and then saying that they were made as part of an effort to adopt gender-neutral standards. Or don't, if you are worried about your liver.)
And that's just showing what happens when there is a difference in
ability, which is relatively easy to test (until the tests are dismissed as bigoted for getting the wrong results). The primary problem in the tech field and many other places is a difference in
interest. That is, it simply doesn't matter if women and minorities are capable of doing just as good job in the tech industry if not enough of them are interested in the field to study the necessary skills. Either way you end with a limited pool of applicants from those to draw from, and of course any search that merely looks for the most qualified candidate will come up with fewer from those groups. But while people claim to understand that and support getting the most qualified candidates, in reality that's just a polite fiction. What they really believe at the end of the day is that numbers should be equal across all groups, because it
must be true that there are equal numbers of qualified candidates from all possible groups.
