Answer 1

because some are geostationary, and others are orbiting, so sometimes there are plenty in the sky above you, and other times there are only a few. In order to stop them hitting each other when they are bunched up they need to move in a synchonised pattern (XRD) of superlatticing and interweaving their trajectories through the crowded field. Eventually society will determine this method is inneficient and put a ceiling on the sky, engulfing the earth in a thin layer of high tech equipment, and this dome ceiling will write the history books as the first major internationally organised and build space structure, paving the way for a human society in space. One day earth will be gone, but humanity will live on.
