In fact, without disaster, human beings can destroy themselves

With the continuous advancement of science and technology, many scenes that could only appear in movies before appeared in more and more of our lives.

The "metacosm" of the recent fire has brought virtual reality closer and closer to us. Will humans live in the virtual in the end? Could it be that, like science fiction, humans only have consciousness in the virtual world?

Human beings have all kinds of desires, food, sex, violence... In reality, because of legal and moral constraints, a person will reasonably control his desires within the rules he formulates. What if it's in the online world? There's no death in the network, and everyone is playing some other role. You can do whatever you want in the game, because you can do a lot of things in the game that are impossible in the real world without paying too much price.

If technology really gets to that point, in the virtual world, it can simulate all perceptions, so that you can't tell which is virtual and which is reality. Will you still be obsessed with everything in the real world? In the virtual world, you don't have to learn, you don't have to exercise, just a little bit of you will master a skill, run never tired, and even fly around. Are you still willing to choose to live in the real world? The food, the beauty, the beauty in the game... It's all the same as reality, and you only need to enjoy the benefits of your quests with monster fighting. Are you still willing to work hard in the real world?

Maybe then everyone only needs a cabin, and then the nutrient solution is constantly infused, and the human bioelectric power supply machine (picture in the Matrix). Or you don't need a physical body, just upload your consciousness to the server (a certain episode in Black Mirror).

It seems that there is no need for the end of the earth, the invasion of alien civilizations, super viruses... Something like that, humans themselves can play themselves to death. Look at the history of mankind, as long as you can make money, you dare to do anything.
