The intro starts of by saying that before computers were seen as a big calculator and now it is seen by some as a way to talk, exchange ideas, and even assume another persona unlike the one we show everyday.  It discusses how the boundaries between real and virtual are breaking down and these forms of communication are being more widely used and accepted.  It then goes into Mud's and how people feel about them.  The book says that someone even says that playing a Mud is more real than real life itself.  This to me seems very disturbing especially when I read on and found out that there are people who spend in excess of eighty hours a week in these Mud's.  I personally feel that for these people to be doing this that there must be something wrong with them or they are missing something in their life.  It also says that on these Mud's people can pretend to be a male if they are a female or vice versa.  In fact they can be a dog if they want to.  This to me seems weird because you are pretending to be something that you are not.  Maybe I am jumping ahead of myself here but that is just the way that I feel.  The intro even talks about something called virtual rape where another player takes over your player and has total control over it.  There are also cyberpsychologists on a Mud not to mention robots who pretend to be real people that can actually carry on a conversation.  She says that we are moving from a modernist culture of calculation to a post modernist culture of simulation.  This to me simply says that we are using our resources in a totally different way.  The intro also talks about cybersex which is something I sure we have all heard of.
