Amusing Ourselves To Death Conclusion

The distinction he makes in the last chapter is the difference between laughing and thinking. He is telling us that the danger of the age of television is that we do not why we are laughing anymore, and we do not understand why we have stopped thinking. This distinction matters because it is the whole reason of the book, it shows us the true decline in the world caused by the age of television. That if we do not do anything about it we will keep being entertained by the mindless shows we watch and sooner or later lose the ability altogether to think for ourselves. In the end Postman is saying all these mindless entertaining shows will be funny to us know but they will control the way we think if we keep watching them.
