To begin with, computers can be used in performing daily chores at the house. For instance, cleaning of the home can be done with the minimum effort and time with the advent of robot maids. In addition, teachers can use computers for teaching their students by staying at their own place. In other words, tutors can arrange multiple classes in different cities at the same time by the help of this tool. Thus, it is obvious that the computer can be used in household work as well as for teaching purpose in the coming future.
However, inordinate usage of this tool has many disadvantages. First of all, human beings will be replaced by this machine leading to the increase in the unemployment which is intrinsically tied to the rate of the crime within the nation. Furthermore, the absence of physical presence of teachers in the classroom can raise the problems of discipline within the students. In other words, social development of these pupils will be harmed and thereby, will cause a hindrance in the nation's social growth. )))
