Reality is that a woman can do better than going into tech. Getting an MBA is easier than an MS in computer science, pays better and hours can be better too. More flexibility in case there is a second dotcom bubble.
Women engineers are underrepresented in every part of the world, and the problem has to be fixed by helping the (mostly female) teachers and counsellors from the primary school level so they can talk about the subjects to girls. The less they know about the subject, the more they'll talk about what they know.
