I think this is really, really important.
We start teaching students the foundations of chemistry, physics, and various areas of mathematics as early as Sixth grade, but Computer Science is largely ignored. Hell, it's hard enough to find a decent CS curriculum in High Schools. Students who would never dream of studying computing might find that they have a passion for it if they are exposed to it early enough (in a kid-digestible way, of course) I remember reading a study (I wish I could find it to cite) that showed that students who were exposed to CS courses early were more likely to have a favorable opinion of the field ("it's not just for nerds")
Finding people who are capable/willing to teach CS is one of the biggest problems here, I think.
