Facebook is betting that we'll want to go fully into a virtual world sometimes, maybe when the realr is it as compelling. A part of this is also bringing it into the real world, the ar component of it, that's augmented reality. That's graphics overlaid on to the real world around you. And i think it'll be a hybrid of both. But what's important note here is that facebook doesn't really care if you or i are into this idea. They care that the kids are. I mean, i think kids have shown that they do love these three day worlds like row blocks and fortnight.
