ExistenZ-Thoughts?

Today in class we watched a movie called ExistenZ. This 1999 science fiction thriller starred Jennifer Jason Leigh and Jude Law. Wow was it different. The basic plot features Allegra Geller, the greatest video game designer in the world, testing her new virtual reality game called ExistenZ. Testing the game, a group of people are chosen from an audience. The movie quickly takes off when a man tries to kill Allegra and Ted Pikul protects her bringing the plot to an intense journey to win the game.

In order to play the game each person must have a bioport. This was a plug placed into the bottom of each players spinal chord. An umbilical looking chord was extended with a controller at the end. The game was powered by each player's nervous system essentially. When playing, each player becomes fully engaged in the game. They can call for a 'pause' or a 'stop' from inside the game. Then, immediately the players pop back into reality. I was thinking throughout the movie I know they can 'pause' or 'stop' the game at any point, but if an outsider, for example, came into the room and needed to ask one of the gaming participants a question would the characters inside the game ever hear them calling? 

I also thought about if this were real life could any of this ever be possible? Could virtual reality and actual reality ever merge?

When I started to actually question whether or not this could ever be possibly I decided that certain aspects could most definitely become possible in the future. Whether or not it is a near future or far I have yet to determine. The progression of entertainment has led to more stimulating gaming experiences already. This has been enabled through the use of physical technology, the gaming controller. This controller has allowed the player more control of the game, and this is stimulating their brains. So, it's probably safe to say that one day technology will progress to the point of a more enhanced stimulating experience that could likely enable the actual gamers to use their brain to control the game. Basically, I guess I'm also trying to say that I do believe certain aspects of virtual reality and reality could merge, but some things are just sci-fi!
