Too Much Laughing

In the last paragraph, Postman is discussing how people are beginning to laugh more and think less.  This distinction is very important because it relates to the main point that he has been trying to get across the whole book.  People are thinking less which means that they are becoming less intelligent. They are laughing more and foucusing on technology as pure entertainment.  This will lead to a dramatic change in our society today and even more in the future.
