And by background I surely mean gender, but also things like educational background, nationality, personality etc.
Nobody should brute force for gender diversity just for the symbolic victory. Diversity done right has its benefits, but like all paradigms you have to use your brains when implementing it. Refusing to do so and then after a half assed attempt declaring it doesn’t work, is what you sadly witness quite often.
I know multiple women in tech and every single one of them had their gender used against them many times during their careers. Hiring men and women like in regular fields won’t hurt tech at all. I don’t really get why it has to be a big thing at all.
If you want someone who can contribute to a team in a certain way, then hire for that.
To my mind, this is the key point. It may be likely that a team with e.g. diverse skills/personalities will end up being gender diverse. But to assume that it has to be gender diverse, or that you can achieve a diversely skilled team by enforcing gender diversity seems to lapse into lazy gender stereotyping about how e.g. women's skills/perspectives are limited by their gender.
