I opened up the link. It does all look fairly interesting. Could you elaborate on the virtual world thing. The thread on Reddit seems to just mention it as if we should already know what they're talking about. Is this something like the Matrix? People would just be connected to a computer and live in a virtual world? I don't really think that's a great idea. I think it could be cool to go to a world like that for brief periods of time, but it's much nicer to just live in the real world. I just had one idea though. Maybe everybody's homes could be in a virtual world. Then you would just require one spot in a chair per person, instead of actually building huge houses. That could be an interesting thing to explore.
