Is that a thing? Say you have this immersive VR game. You are ...Adam. There must be a first and you are him. You poke around for a few hours interacting with your environment when suddenly you meet someone.

Surprise! This is a new user and all of their state started out as a fork of your state. You and user number two, Eve, are a "bifurcation" of your experiences and feedback. They are a fork of your game state.

In practice, when we're ready to onboard Eve, we just take you, make a clone, transport to where ever Eve spawns, and Eve takes over the controls (she is born!)

Eventually she wonders around and meets you. You oddly seem to have a lot in common. Via some algorithm or whatnot, either your or Eve are cloned to create user number three (Like, one or the other. Not a combination. You're thinking of sex.)

And so forth. The n-thousanth user has a world that is the result of the path taken all the way back to Adam. So you have a unique path through the tree of life. You have a lot in common with some and less in common with others. People lump into identifiable tribes and "know" each other in a way that is integrated into the game state.

As the number of leafs in this tree grows, the more next-user bandwidth there are (i.e. any one of all users can be selected.)

Profit?
