In the reading piece migartory city，the most significant difference between city in real life and the scifi-city is that the migartory cities are not considering enough real life problems. A city in real life needs to consider energy, water and other problems, as a stationary city it is quite easy to get consistent souces. But in the passage, the migartory city can move with huge legs, wheels, and even monsters leading the city. Therefore in conclusion, real life city needs to consider many aspects, city in scifi-novels ignores many physical principals and other problems. It only focus on maybe one aspect, in this piece is that whether the city can move.
