This is the near future. Gene-editing technology has developed rapidly. A scientific life form called “humanoid” has been created. The physiological structure of humanoids is almost the same as that of humans. The only difference is that the neurons in their brains have been gene-edited in a certain way. They have a sole initial obsession that must be obeyed. They can be loyal spouses until the end of their life. They can be meek and filial children. They can be employees loyal to their boss. These custom-made humanoids started to circulate as commercial goods in the worldwide. Even in some countries where production and selling of humanoids are illegal, there are still outlaws who bring humanoids into their country without permission and sell them secretly. Along with the wide spread of humanoids, their risks gradually emerge. More and more people started to be addicted to the fake emotions provided by humanoids. And for humanoids themselves, their thoughts and emotions are easily deformed under the restriction of the initial obsession. Many malignant incidents happened due to that. In the face of the more and more serious situation, the international society quickly held a meeting. The production ban and recall of humanoids were approved unanimously. According to the agreement, all nations will stop producing humanoids immediately. They should also recall and centrally manage all the humanoids in their country.
