If I was going to go out on a limb, I'd say a large part of the reason women aren't drawn to tech at a young age is because it requires you sit alone in front of a computer talking to it for long stretches of time instead of interacting with other people, but I have as much evidence as you do that it has to do with a lack of role models. (I got into programming well before I knew any famous programmers.)
