The Complete Model

It all started with an attempt to predict the outcome of coin-tossing. A complex model was developed. Give air conditions, mood and geometry of hand of tosser, the model could predict whether it would be a head or a tail. Accuracy was improved as years passed.
Now someone came up with this: why don't we enlarge this model to cover all of the world? A model was developed. A big computer contained algorithms of the model. It was a preliminary model. It needed a large amount of data to begin the process and accuracy was not very impressive. But both of the problems were getting solved as more resource flew into the project. The computer was getting bigger. Initial data requirement was coming down. Accuracy was improving. Computer getting bigger was a problem. So compact machines were developed, with greater complexity.
As time passed, beauty of the model set fire to men's hearts. At one point of time the model became indistinguishable from the world it was created to predict. And people never bothered to go back.
