As a boy, and a "nerd", I grew up on the VIC20 and C64 from grades 4 to 9 in the 80s, later to become one of the "Amiga generation" I guess. My friends were other boys who liked to tinker / obsess with computers. We weren't amongst the cool crowd then, but it didn't matter (too much). Number of girls I met who ever tinkered with one? None. It just didn't happen. (Asterisk: This was true for a sample size of one Norwegian school; YMMV.)

We would have loved it if anyone did, alas that wasn't the case. I'm glad things have changed and you're no longer an outcast if you're a geeky kid; I feel that I paid a big personal price for being that way inclined, but later on there was a payoff in that it was easy to get into programming as a career, when the Internet started happening in the mid late 90s.

If my next kid is a girl, she'll have no shortage of computer science ahead of her. My son's already way deep. :)
