Why DON'T we teach computer science earlier?

As Gail mentioned, we got to chat with the girls@vv girls this morning, and they had some really interesting stuff to say about why girls aren't interested. Here's a teaser from my post:

So it got me thinking, why don't we start earlier? I taught my sister how to program when she was in elementary school.

My brother and I learned at 13 from a book for kids. So why don't the schools teach it?
