Modeling Reality with Virtual Worlds

These different virtual worlds can be used in a few atmospheres such as social, gaming, and healthcare.  In the New York Times, Dave Itzkoff says he was able to leave the jam-packed club and enter it virtually when he arrived home, almost like Grand Theft Auto, except its way more realistic.  One problem that I foresee is that virtual reality becoming too addicting for introverts or those who are just lazy to go out and enjoy the natural sunlight, which would then lead an even higher increase in obesity.  However, there are some benefits to virtual reality as well like connecting with an old college classmate that's now in Europe while you're still in the U.S.  In addition, this might be good for disabled people who don't have the mobility to travel from place to place. I think that in the future virtual worlds will accommodate us individually, such as our room, right now we see 4 walls made up of sheet rock, concrete, and wood behind all of that. Instead, our walls will be built in a technological way where most of our tools like computers, tv, a mirror, or even a view of the outside will all be embedded into the wall itself with tiny circuits running behind the screen wall.
