The use of robots
Currently, it is arguable that artificial intelligence is advancing by leaps and bounds. It is reasonable to believe that robots will be more and more like human beings, both physically and emotionally, hence playing an important part in the industrious field.
To begin with, robots will do the laborious jobs, such as delivering packages and other chores, thus let people do more meaningful things. Further, they can work continually if only they got enough power which means the huge boost of efficiency. Economically, they can save the cost of the industry as their production fees are way lower than the salary of workers. Moreover, life will be joyous with them. They know what their masters favorite, include songs, foods, and clothes, etc. Your daily life will be arranged properly by those robots based on your preference.
Granted, the use of robots has a lot of advantages, and we should be careful not to make them too smart to occupy the earth and turn us out.
