If a particular group is underrepresented there is a reason for that. It's not necessarily your fault, although unless you're very aware of ingrained sexist structures it's possible that you're contributing accidentally. It turns out that the reasons for the imbalance aren't good ones. It's not that women just love to do other things - there are pressures that actively dissuade them from pursuing technical careers. Most of this has happened long before they acquire technical qualifications and are applying for jobs. That IS sexism in our society, and it's not fair.

So where does that leave us white males working in tech?

1. We have to recognise that the gender imbalance is a problem and accept that it should be solved

2. We have to recognise there are ways we can help that are NOT simply "hire a weaker female applicant just to balance the genders"

3. Promote female participation! Sponsor school programs. Create female-only internships. Make sure that everybody in your workplace is actively educated about structural sexism so that things are as comfortable as possible for your female employees. Ensure salaries are equal.

We need to help send the signal to young women contemplating their careers that the tech industry welcomes them. Then, maybe 5 or 10 years from now, we'll be getting closer to equal applicants.
