In a sense I'd argue that this has been happening ever since the advent of the Internet. It's just becoming easier to coordinate as hardware and software continues to improve. For example, I haven't worked from an office in 4 years and my current company is about 80% remote and distributed all around the world. I consider myself a member of dozens of different communities that are running on different platforms. With the advent of virtual reality and projects like Decentraland, visualizing these communities may be taken to the next level.
