We in fact thought of starting the "GoTechgirl" program. It was for exactly that reason. We produce T-shirts and graphics. It is positive, interesting and creative. Girls need to be in a special club for themselves where they can ask questions and get answers in a situation where they are just among themselves and not in competition with boys.
So we start in grade 7, talking to them about careers and occupations. It has to be positive. The competition works and is for all the people you talked about.
That is why I have 14 different hats in my office. Whether it is architecture or mechanical and electrical work, what is essential is to give the teachers, and most importantly the parents, the information to persuade them, for example, to let their daughters do what they want. If they want to do it, they have to be given the opportunity. It's positive and it is happening.
