I agree that it is not to sit at the computer all day. Controlling it's use is necessary. However, banning the computer is definitely not a solution. What if a student has to submit an assignment within two days? How will he/she gain instant access to reference through ebooks and from websites?
What about the industrial sector? Imagine the situation if the computer is banned for two days. Business, trade and commerce today are dependent on fast-track communications.
Industry will slow down if computers are banned. The stock market will plunge. The economy will suffer.
Imagine being cut off from your friends or relatives for two days every week just because you are not allowed to send emails or indulge in chatting for two whole days. Unthinkable! Unreasonable!
We will just have to live with the fact that computers are here to stay. There is no way we can do without them. As students, all we need to do is use the computer judiciously and sensibly.
