Nvidia CEO Jensen Huang told Time Magazine that he wanted to create a metaverse which is "a virtual world that is a digital twin of ours".

Huang credits author Neal Stephenson's Snow Crash, filled with collectives of shared 3-D spaces and virtually enhanced physical spaces that are extensions of the Internet, for conjuring the metaverse. This is already playing out with the massively popular online games like Fortnite and Minecraft, where users create richly imagined virtual worlds. Now the concept is being put to work by Nvidia and others.

Partnering with Nvidia, BMW is using a virtual digital twin of a factory in Regensburg, Germany, to virtually plan new workflows before deploying the changes in real time in their physical factory. The metaverse, says Huang, "is where we will create the future" and transform how the world's biggest industries operate.

Huang said that the digital world or the virtual world will be thousands of times bigger than the physical world.

“There will be a new New York City. There'll be a new Shanghai. Every single factory and every single building will have a digital twin that will simulate and track the physical version of it. Always. By doing so, engineers and software programmers could simulate new software that will ultimately run in the physical version of the car, the physical version of the robot, the physical version of the airport, the physical version of the building. All of the software that's going to be running in these physical things will be simulated in the digital twin first, and then it will be downloaded into the physical version. And as a result, the product keeps getting better at an exponential rate”, Huang said.

Humans will enter and leave the two worlds through wormholes which use virtual reality, and the objects in the virtual world, in the digital world, will come into the physical world, using augmented reality.

“Pieces of the digital world will be temporarily, or even semi permanently, augmenting our physical world. It's ultimately about the fusion of the virtual world and the physical world”, Huang said,
