But, my point is that my kids lose all their confidence and all their patience, and they become tentative and fearful. They show all the same symptoms that were mis-attributed to age in the above comments.
On a game console, my kids are not afraid to explore every menu and push every button. In a text interface, they are lost and they don't try things. They seem to learn slowly and they don't seem to listen to instruction because of how different text UIs are from the GUIs they know. When I get a new text interface, I know all kinds of things to try, and I do so without much fear.
