Eek, A Male
If I had to choose one of the following, to improve society:  a). More women in tech
  b). More men in childcare/teaching

It'd be 'b' without a doubt. As said elsewhere, the complete lack of any male role models at a large number of schools is astonishing and very worrying. Is it any wonder girls are performing better than boys these days, as the number of male teachers has decreased to almost none?Great to finally see an article like this one.
