Have you ever thought that people would keep their relationships by the internet one day? Now, do you imagine that people will just keep the relationships with robots in the future? Anything is possible! Recently, I notice a stange online phenomenon about the posted videos. Among a variety of online videos, one kind of videos are really popular. All these videos have a same background: the end of the world. At that period, it's either very hot or freezing outside. So, people prepare enough food and other essential items for the living, and then hide in a cave until the outside world turns habitable again. The indoor live is really simple which just contains Eating, sleeping and doing chores. All of them smile and enjoy their cave lives. Phones and the internet are just used to monitor the outside. Though these videos are created by AI, the popularity of them reflects that nowadays, people are deeply confused by AI and really want to have a simple life like their ancestors . If there is something you don't like it, but can't leave it, everything becomes complicated!
