There are some unsolved mysteries in the real world that people find difficult to understand, such as the double-slit experiment, you observe it, it comes according to your ideas, you don't observe it, it comes according to its own ideas. This experiment, which was many years ago, has not been solved by our scientific and technological progress, but has become more and more incredible. It is precisely because of these inexplicable and strange phenomena that some people have proposed that our world is a virtual world.
We can enjoy it, if we have enough room to run, and then create a world in the virtual space, the NPCs in it have programming with autonomous AI, do not make specific specifications for their behavior, then what will we find when we observe this virtual world, will the NPCs in our virtual world study the bugs in our virtual world, will they feel that their world is virtual?
After the development of NPC AI in the virtual world to a certain extent, will it create a smaller virtual world? If we transplant the AI of mature NPCs in the virtual world to reality, does it belong to the trans-latitude "flying immortals"? Zhuang Zhou Mengdi or Butterfly Mengzhuang Zhou, whether we are npc or protagonists.
Human beings always face the unknown with countless problems, these problems are also the basis for guiding our continuous development and progress, in fact, whether our world is real or virtual, we do not have to worry too much. For this kind of problem that plagues all mankind, we need to think, but we must not fall too deeply, and we must learn to withdraw our minds at any time, just like a grain of sand thrown into the sea, if it is not withdrawn in time, it will be lost. Each of us is real to ourselves, and family, friends and other people are also real to us, so whether you think you are npcs or protagonists, please be kind to everyone around you and cherish the moment.
