5.Robots

Several individuals believe that finally all occupations will be operated by robots that have intelligence equivalent to human workers. Yet, from my point of view, this prediction is not realistic and my reasons will be discussed in this essay.
First of all, it is undoubted that robots are acquiring great progress in terms of their intelligence. With the high capability and network systems, smart robots would be able to deal with varied works instead of human beings in the near future. However, even if there would be brighter robots than human beings, we should be responsible for some critical jobs considering some disadvantages of robots. By way of an example, consider the role of politicians. Robots are often threatened by hacking. While politicians have to make important decisions for the country, robots can be manipulated by enemies such as terrorists on account of their network systems. Given by this, it is needless to say that robots cannot be in charge of political works.
Moreover, we also need to consider about our emotional matters. Although high class robots can learn and express emotions like human beings, quite a few citizens would still hope to communicate with real human. Accordingly, replacing all employment with robots should be difficult. For instance, the aged who are in a nursing home sometimes suffer from feeling of lonliness or alienation. The thing they want is real interacting and meeting with real humans, not human-like robots. Thus, working robots probably cannot fully help them.
In conclusion, considering the reasons mentioned above, I suppose that we would need human workers in the future as well.
