The reason to go out and talk to students (all the way from middle school to college) about tech is to dispel the myths that it is a tough field for girls/women. That there is no such thing as tech is for boys/men. All the way from long haired pretty princesses, the image is all messed up for girls! And it takes a lot to correct it really.
Legitimately, after showing the possibilities that tech can bring, if someone makes a choice it’s not for them, that’s totally fine. The point is not that tech is superior to any other field — it’s just that there isn’t enough talk about tech for girls and women to even form an opinion about it.
