I don't see why sex matters. Women are already preferred 2 to 1 over men with exact qualifications in STEM roles. Equality means that gender should not be considered. We are individuals. There are plenty - and I mean plenty - of fields where women dominate and we see no diversity programs. Teaching, nursing, child care, human resources, administration, and dozens more. 

Guys get ahead in tech because they are willing to sit there for five years in front of a computer to get stellar with code. Much fewer women seem to WANT to do this. It's not whether they can, but the interest is less. There are women tech leaders by the way.  However companies that hire women CEOs because they are women usually fair pretty poorly with shareholders. Companies should just hire the best CEO period. The one that will deliver shareholder value. That could be a woman or a man.
