This is a short one, but here it goes.
The most common use of technology and the one that’s been told a thousand times in entertainment is the use of virtual reality; a world more immersive then the world we live in now and if we die in the virtual world, we die in real life. Big stuff. For psychological reasons, many of us want to escape. We do it every time when we return home from work, from a date, from a scary hospital and we want to look at kittens for relief. It’s popular, but it’s a suicide at large if you think about it. Whether you liked Sword Art Online or not and how it’s gaming references and love story experiments such a gathering, elements in the show portray a double jeopardy into how we see ourselves as different people and how we wish to spend the rest of our days.
The individual’s life serving in an alternate reality increases when they break limitations they never thought they could do before, gaining skills, dressing up, traveling anywhere, and fighting monsters. Using a helmet and connecting the consciousness into a video game where millions of others can meet up is a growing trend, but it also serves as a means of going to a world after death through means of killing the player (if the player has no desire to live in the real world and wishes to have more time to be in a world that's meaningful). Hence the story of SAO when the creator traps players in the game with no way of turning off the game or they’ll die. Many of the main characters and other players in the game, some of them are carefree of the idea, most of them question their lives of how they will adapt in a video game while their bodies in the real world decay slowly. Addiction, confusion, low esteem, anxiety, and physical and sexual behavior are signs of playing so much and the characters show these. Kirito is a loner in the real world and the virtual world and is scared easily when players ask him to join a guild and flirts with some of the women. Other players are at risk because higher leveled creatures and players roam around twenty four hours a day. Their personal heaven. And I don’t even want to imagine what happens to their blander and bowels in the game.
But even when the desperation sets in, Kirito and company still help players and not want any of them, who are weak to carry out their own lives while playing a game, to feel like they're scared. Kirito shows these signs very consistently, and he himself is someone who has had a troubled past and his two year coma is a way of going out. At least until he wakes up.
