Growing up watching shows like "Dexter's Laboratory" and "Jimmy Neutron Boy Genius" definitely shaped me as a child into the tech freak I am today. Girls getting barbies thrown at them when they are 12 does not help put girls into the tech sector. We need television shows like "Diane's Laboratory" or "Jennifer Neutron Girl Genius" to get girls interested in tech. Hit 'em when they're young.
Girls don't get barbies thrown at them, they beg for them. The are expensive, too.
What we tacitly expect of kids does shape them, to an extent.
