We'll nobody programmed in general since computing was so new. The industry is just significantly larger now. The trend though I think is that computing has gotten huge but actually developing that computing hasn't grown at all in the youth group, just the consumption of that computing. You lose a lot of tinker-ability when you move to GUIs and especially when you don't distribute developer tools or learning resources.
I mean, think of the generation growing on iphones. How would they ever get exposure to programming or tinkering on a device like that?
