I went over to a friend’s house the other week for dinner. When I got there, I saw something that amazed me. At the kitchen table, there was his three year old son, on a MacBook, watching YouTube videos. It seems that his son figured out that clips from all of his favorite cartoons were online at his disposal. I asked the father where he had learned how often he does this, and he replied we can’t get him off of there, he’ll be at it for an hour.
