I thought this internet application created by http://lindenlab.com/" [Broken] was interesting: http://en.wikipedia.org/wiki/Second_life http://secondlife.com/ It takes the idea of a video game to an extreme. Video games normally either capture some specific portion of real life (i.e. life car-racing, or war, or airplane flying) really well or try to introduce like a complete fantasy world. "Second Life" attempts to reproduce the entirety of the real world in a video game with little embellishment or anything. This has been done before in games like "The Sims", but I think the scale on which "Second Life" tries to capture normal human life is new. People are using Second Life to actually replace real-world interaction. For example, businesses are holding meetings in the Second Life virtual world, educators are having classes there, etc. I'm sure they save tons of money doing that. It allows people to create an identity as a character in a virtual environment. For people who are physically handicapped, this might be an amazing opportunity for them to experience normal lives. But, there are really a lot of philosophical issues involved. Should we be worried about people getting so absorbed into their "second life" that they forget about their "first life" in the real world? I don't know whether I should be scared of Second Life or consider a innovative and beneficial use of technology and the internet. There is always the Matrix scenario lurking in the back of my mind...I am not really sure whether Second Life is a step towards that or not. There are also some interesting economic issues this raises. Apparently, people are making transactions on Second Life and converting that to real world money at "several thriving online Linden dollar exchanges". I would be interested to learn more about how that works. Does anyone here have a "Second Life" account? What do people think of this?
