Could you please check this short essay for me if I write it in a correct IELTs form and style? Title: Some people think that robots are very important for human's future development. Others think that robots are a dangerous invention that could have negative effects on society. Discuss both views and give your opinion. With the development of new technology, more and more robots are invented in recent years. Both positive and negative concerns for robots are rising as well. In my opinion, robots can benefit human's lives if they are used in a proper and effective way. The invention of robots is a great step for human beings, which appears in three main aspects. For the first aspect, robots can replace those people who participate in hard and dangerous work. For instance, most workers do harmful work in factories and touch with those poisonous products all the time. Secondly, robots with humans' appearances are going to become good friends accompanying with those lonely people and taking good care for them. For the last but not least aspect, robots can shoulder the burden of solving those important problems which require a large number of accurate calculations. There is no doubt that robots can deal with the complicated statistics much faster. However, negative effects should not be ignored at the same time. Some fiction movies talking about robots show that robots in the future are going to harm or even kill human beings, which is also true for the real world. Recently, a robot called 'Sophia' which looks like a real person as well as having individual emotions has been invented. The society will be disordered if robots are hard to differ from real persons in the future. In addition, though robots can take the dangerous job, an enormous number of them would lead to the unemployment which can make the social unrest. To sum up, although the invention and development of robots bring convenience to the society, it also caused serious problems if they were used without limitation in the future. What people should do is to take enough control of them from now on.
