I think in the near future we will see how companies that are engaged in virtual reality and the development of the virtual world will unite among themselves. Since this world is unlimited and 1 team does not really realize everything properly, everyone should contribute to the development of this industry!
I do not agree with your idea that companies that are working to create a virtual reality will unite. I do not see practicality in this association. In addition, I'm more attracted to diversity than monotony.
