Computer Aided Catastrophe

We people are now experiencing a technological revolution, where computers are being used in almost every aspect of life. Some people think that it would be good if computers are used without any human touch in areas such as defense, among others. This will of course be more efficient but we should consider this; some people will always find a way to destroy what is good. An example ,in this case, is  some programmers making computer viruses in order to disrupt the daily activities of fellow human beings. With this Kind of people, we are warned not to entirely rely on computers to anticipate failure. There should be a human touch in every aspect of life where computers are in use.
