We imagine "pure" cybernetic systems, but we can prove only that we know how to build fairly dysfunctional ones. We kid ourselves when we think we understand something, even a computer, merely because we can model or digitize it.
We already knew that kids learned computer technology more easily than adults, It is as if children were waiting all these centuries for someone to invent their native language.
The mass culture of childhood right now is astonishingly technical. Little kids know their Unix path punctuation so they can get around the Web, and they know their HTML and stuff. It's pretty shocking to me.
