I have two kids. The time at the computer is deliberately limited, so they aren't into games that much, although they like the online games, etc. Not into programming either, they didn't even pose a question 'how is this program made?'. To them it's more like a whole self contained thing. Like a car. You don't sit in a car and say 'I don't like the curve of this seat, I'll hack this afternoon and see if I can come up with something better'. I hope you get an idea. What they do like about computers, is that they can use them to create something - drawing, presentation, writing. In fact, both are really into writing - trying to write novels and short stories. So computer to them is like a tool, which you can use to create something, but not modify itself.
