It has been ten years since the first season of Swordsman was broadcast. Time flies so fast. I have watched it many times over the past ten years, especially the first fifteen episodes of the first season. Looking at the sword once in the afternoon is simply a great happiness in life.
When I was a child, I always looked forward to the release of SAO in 2022. Now it's 2022, and I haven't even seen a single movie. But there's been a lot of buzz about the metaverse recently. In fact, the light novels of Sword Art Online that have been serialized since the beginning of this century have discussed this as early as 20 years ago.
From Descartes' "I think, therefore I am" to the gradual improvement of the concept of ontology, it is not difficult to find the world of Sword Art Online with thinking about the concept of ontology. The boundary between the real world and the virtual world is gradually blurred. The senses are subjectively "real" after full stealth. Although the world after full stealth is objectively false, the definition of falsehood is also derived from the real world.
But imagine, what if one was born in a world of full stealth from the start? What if the baby was born with the Nevergear? For him, the virtual world is the real world. It can be said that the world of full stealth is known and actively entered into the "brain in a vat". The Matrix discusses the authenticity of the objective world, while Sword Art Online gives great humanistic care in the virtual world. I think whether it is Kirito or Asuna, if there are no constraints in the real world, they will definitely want to live in Aincrad. Whether it is a movie or a novel, or a virtual world composed of numbers and programs, the emotional experience in it is always real and equal in weight to the real world.
As far as the metaverse is concerned, it may be that in the next few years people will enter a virtual world after wearing VR glasses. Although it is not completely stealthy, the principle is the same. Our perception of the real world comes from our senses. Although VR devices can only simulate visual and auditory perception, with the advancement of technology and the gradual improvement of technology, when all senses can be simulated in the future, how should the real world be simulated? What about the definition?
