So iv been watching a few episodes cause it was recommended to me. I feel as though the show kinda goes downhill and becomes uninteresting. Many plot holes and time skips. Also Kirito has no personality. The full dive system is badass I admit. The thing about this show is that full dive technology was released in 2022 which is literally impossible to have full dive in 7 years from now. Another reason this game won't ever become real is that this game would take years to develop and many more to test for bugs which I'm surprised that the show never encounters any bugs in the game. That is a huge mystery. A game of this caliber would have bugs to an extreme amount even through many betas which the game had 1 beta which would not bring the game to perfection or close to it. If anybody thinks this game will come out in our lifetime then it won't for many reasons and also due to extreme research through the brain and be able to be put in a dream like state and control avatars through the game with our mind and be able to replicate senses from the brain and transmitted to the game which like I said earlier is impossible at this point in time but will improve over time. If this game were to come out it would also cause a very bad addiction but on the positive side it could be very therapeutic in many ways for people stuck in hospitals or something like that. Not to mention Lag would be horrific in a game like this if occurred. Anyways that's just what I know and my dad is a neurologist so he explained this stuff to me since he's also a gamer on the side. Not trying to be a killjoy but take it from someone who's been researching brain development and senses research for 10 years.
