The computer is the most important invention in last century.And a number of scientists,businessmen predicted that the computer would become more and more dependant in our life,and that this trend would last at least 5 decades.However,it surely has made our life easier,but in some ways,it makes our life no longer trustable,safe and simple.
Our life changed,for the internet has become dominant and crucial part of our life.We almost do everything with the help of the internet.We chat,read news,and even buy things on the net.Here is where the problems lie.We chat with someone,whose name,nationality,occupation is not known.We may not care about these,but if he or she is a bad person,a criminal,a terrorist or even worse,then how do you feel?Therefore,though we can chat with friends from all over the world,we just cannot believe what they tell us.Such unreal world makes you feel trustless.This uncertainty is a thief who steals the feeling of safety.
There are also some problems with what you might see on the net.Undoubtedly,you will see what you are looking for.But more often you might see something else,such as violence,sex,which is a trouble not only for you,but also for your children.These unhealthy information might have bad influence on the juvenile.In addition,sometimes,some kinds of eye-catching ads are,in fact,a swindle,or a virus,which rob your money or waste your time.Thus,you may lose your simple life.
Buy things without stepping out of home sounds fantasy.Now the internet makes it come true.However,can you then surf without alert in the brilliant pictures of the goods?I shall remind you,what you see are just some beautiful pictures,you cannot touch the articles; either can you know whether the quality is satisfied.We know that cheap things are not always high quality things.Even if some companies allow you to pay after receiving the commodity,and if you are not pleased with the real goods,even though you are lucky not to waste money,you still pay your limited time.Above are the disadvantages that the computers bring about.These cause the life to become complex,unreliable,and untrustworthy,which is not a right direction to go.So we should take these problems into account.Only if the laws and the system is well provided should the computer really improve our life quality.
