What would you do with such technology if you had access to it? What would you like to do with it? and would you still be interesting in traveling in physical reality?
Inside a future fully immersive virtual reality, you would be able to experience for example: Paris France in all it's glory and landmarks, you would be able to feel the wind blows, taste the food, the sound, the textures of the city just as if you were physically there. Computational power will reach a point in which you could simulate all of Earth's landscape and landmarks to of indistinguishable from the real Earth. You would have access to all these landscapes without traveling thousands of miles. You would not use a mouse or keyboard to experience it (although you maybe given such an option) to control you new body. You would control your virtual body just as you would control your physical body through physical reality.
Ray Kurzweil makes speculations about the future of computer/video games.
He speculates in the coming decades. This is just a prediction based on current and past technological growth, but he has made many accurate predictions in the past so he has a high case of credibility.
"we're going to put it in our eyeglasses, it'll be memory images right to a retina and put us in a three dimensional full immersion visual auditory environment so rather being in here it'll be three dimensional and all of three dimensional out there will be in this three dimensional environment and will be able to walk around and we're like, to feel like we'll be able to look at ourselves but wouldn't necessarily have the same body that we have in real reality and it'll become more and more realistic, "
few decades on " nanobots, these blood cell size devices will be going in our bodies keeping us healthy from inside. We'll have some go inside our brains to the capillaries not invasive, there would be interacting with our biological neurons so it'll extends our memory, our decision making faculties, put our brains on the internet and they also enable us to enter virtual reality environment from within the nervous system. So, for on to go in the virtual reality environment, the nanobots will shut down the signals coming from I realize in my real skin and create the signals that will be appropriate for the virtual environment and that will feel like I'm in that environment and I'll have a virtual body and those environment could be the same body I have in real reality, it could be a different body "
Essentially, he speculates eventually virtual reality will have the potential to be so realistic that it will be just like physical reality from a feel/sight/touch/sense perspective. But will experience custom made laws of physics and landscapes.
Inside such virtual worlds, we would be able to create land masses and planets that the laws of physics will not allow. such as floating land masses like the Outlands of World of Warcraft and the movie Avatar. We will be able to have a very realistic but different body from one of physical reality. Right now I am a 5 ft 8 male, inside such reality I could redesign myself as a very attractive female run-away model look for instance.
Video below sums up his prediction.
