Elon Musk’s argument: “the probability that this universe is base reality and not a computer simulation is one in a billion” is quite right and logical.
He might be talking about the present or maybe be this argument fits the fact that we are evolving in such a way where we would ask the difference between reality and not real. Technology is being the fastest athlete in the world right now and the upcoming fastest thing sounds something like "Virtual Reality".VR is the next thing in the future. You'll probably never get the chance to go to Mars, swim with dolphins in the ocean, run an Olympic 100 meters, or sing onstage with Zayn Malik. But if virtual reality ever lives up to its promise, you might be able to do these in your dreams and reality as well—and many more—without even leaving your home. Unlike real reality (the world in which we breathe), virtual reality means simulating bits of our real world (or completely imaginary worlds) using high-tech computers and sensory equipment, like headsets and gloves, motion simulators. Apart from games and entertainment, it's been used for training airline and military pilots and surgeons and for helping scientists to solve complex problems such as the structure of protein molecules. How does it work? Let's take a wider look!
Virtual reality is an artificial environment designed with the help of many software and virtual reality devices. It will help the user to experience them the real environment due to the presence of graphics and interactive features offered by virtual reality gaming consoles. The easiest form of virtual reality is a 3 Dimensional image that is virtualized on a personal computer. Virtual Reality in gaming points to the use of audio and graphics technology in games where the users use head-mounted displays (HMDs), sensor gloves or glasses as part of their experience. It offers a simulation of a real-time environment for education, invention, training and desire purposes through a story or a game. In virtual reality gaming, products such as sensor gloves and head-mounted displays, sensors are being used that trace the movement made by the user/player and the data is fed back to the system which analyses the data output and transforms the virtual actions into a functional response on the screen.
With the advancement in this world, and tech things being the trendy motion, VR will have a great future and then we might be literally able to make our dreams come or feel true.
