AI

Yesterday I watched a movie named "AI" directed by Steven Spielberg in 2001. It is quite a good movie. I was moved by the little robot named David who longs to become "real" so that he can regain the love from his human mother. He believed that the Blue fairy who exited in the fairy tale his mother told him could make him become real. So he tried his best to find Blue fairy with the help of another robot and his toy robot Tady. However, he failed because fairy tale was not true. Finally he found the statue of Blue fairy under the water and prayed to Blue fairy for thousands of years until he was short of charge and was freezed. The astonishing thing is that human beings had extincted after 2000 years. David was waked up by the new masters of Earth who look quite cute and thin. They were quite interested with human beings and surprised by the human culture,technology, and civilization. They got a lot of important information from David about human beings and they wanted to make him happy. So they promised to make his mother alive but only for one day. The reason for that is once an individual space time pass way has been used, it could not be reused. Anyway, David lived one day with his mother without anyone else which became the most happy day of his entire life. The story end with the sleep of David and his mother together. But my thinking has not stopped. I was wondering whether it was possible that the Earth's master is a kind of cycling replacement, which means that every civilization has a cycle. Human beings invented robot and were replaced by robot. Then robot tried bring human beings back and again were replaced by human beings. It is a kind of cycling loop until the end of the day. Although I mentioned robot here, I did not mean that it was definitely robot rather than other creatures. I find it is quite interesting to think like that. But the most interesting issue to me is the word mentioned in the movie that once an individual space time pass way has been used,it could not be reused. It really makes me a kind of confused but also makes me thinks a lot. I really want to know that whether the past can be bring back into present or even future and where is the lost information goes to and becomes what kind of state, energy or mass, or other kind of state which is not found yet. The world is really full of unknown.
