One of the most important changes can be found in the fact that we now routinely experience simulation confusion, in which we mistake realism for reality and think some of these fakes and simulations really are what they imitate. We experience simulation confusion when we receive an advertisement in the mail that is disguised as an official notice, and, at first, fall for it and assume it is an official notice. And we experience simulation confusion by accident, rather than by other people' s design, when we make a telephone call and speak to a voice on the other end of the line, only to realize a moment later that we are talking to a recording on an answering machine that reproduces the qualities of a live voice. There is no question how so many simulations came to fill our surroundings. They are made possible by technology as well as by human ingenuity, and they are being brought into existence to fill a multitude of needs and desires.
Simulations provide the military with new and more effective forms of camouflage.
Simulations make it possible for children to collect their own imitation children, in the form of lifelike dolls that imitate an increasing number of human behaviors. And simulations provide all kinds of opportunities for consumers to enjoy the taste of sugar without the calories, to enhance attractiveness through cosmetics, to own replicas of works of art and to experience the fictional characters and situations provided by the imitation realities of television and film. In the kind of economic and personal calculations that go on today, the simulation is often more appealing than the original. For example, homeowners who would like the benefits of a watchdog without the bother now have the option of buying Radar Watchdog, a home-security device that plays barking sounds whenever someone approaches the house. In place of a dog, they get bark masquerading as bite.
