Modeling Reality with Virtual Worlds

Virtual worlds can cater to many differing backgrounds and has many uses. Some uses these worlds simply as a way to get away from the real world, to play as something else. Others can use it as a fun new way to have meetings from people around the world. From "At Hearing, Real and Virtual Worlds Collide", even large companies and government officials could use virtual worlds to meet together and chat about anything. In their meeting many questions were asked because, "in an era in which technologies can catch on and become mainstream quickly, the subcommittee on telecommunications and the Internet wanted to know some basics."
Using the technology could be very useful because it can give a sense of presence being there in the virtual world with others. As if you are almost physically attending something. On the other hand, it could also be choppy, unrealistic, and might even get out of hand if people aren't even really at their computer screens.
I personally enjoy mmorpgs and the idea of a virtual reality. I have great hopes in its developments as both a great use to be used professionally, and recreationally.
