This science fiction’s main idea is focusing on that people’s excessively depending on machine in the future leads to the end of human civilization. Vashti, the mom, is one of the most typical examples of people who are crazy about machine–staying at her cell house “where buttons and switches everywhere–buttons to call for food for music, for clothing”(4) underground all the time, having no interest in traveling even visiting her son Kuno. However, Kuno is an opposite example–a rebel who wants to visit the surface which is not permitted.
Human beings created machine. Machine obeys human’s order. But in that world, people worshiped machine as a god. On the air-ship, all the passengers were shouting “How we have advanced, thanks to the Machine!”(8) They completely forgot it is human who creates those machine.
It seems that Kuno is the only person who is clear about machine. He said “we created the Machine, to do our will, but we cannot make it do our will now. It was robbed us of the sense of space and of the sense of touch, it has blurred every human relation and narrowed down love to a carnal act”(13). Without machine, human has no longer any ability to survive. So the genocide of human is undisputed. Compared to other movies like I, Robot, AI, this novel gives us a deeper cautionary that in no way will human beings get advantages if we over depend on machine.
