What Will Computers Be Like in the Future?

Now computers are developed very fast. Also, in the future they would be more useful.

For example, I think computers will be able to talk with people; for example, computer will be able to write writing without typing. If so, blind people and elder people can use computers. Also, they will do housework instead of mothers.

Moreover, I think textbooks will disappear, so students bring their personal computer in the school, and they will study as watching web site like our computer class. If so, waste of woods and paper will disappear. On the other hand, people who sleep in the class will increase.
Development of computers is very good, I think. However, if it continues as it is, I think culture and tradition will disappear, and all countries become the same. Is it good? When I watch movies like X-Men and i, Robot , I felt future was horrible. Therefore, I think we need to think it seriously.
