Station Eleven

This is a disaster story. In my opinion, the story is nearly a disaster itself. The chapters abruptly jump forward and backward in time. Although most of the people on earth die, I believe that the author overestimates the negative impact this would have on humanity. It is as if any survivors lost most of their intelligence in the process. You could argue that we only get a glimpse into the lives of a few people in a small area of the world. However, it is very difficult to believe that no survivors in the world, knew enough technology to keep some communications going. An amateur radio station doesn't need much power to reach the world. Alternative power sources for radios are relatively common. Wouldn't some dictator in oil rich lands, seize upon the opportunity to conquer the world? Any number of possibilities suggest themselves - but I just can't imagine why the author wants to believe that all the survivors would be shell shocked for a couple years, and then be stuck in the technology of the middle ages.
