- Why does everything the politicians do with the time visor fail, while what Jennings does actually works? Because of the way they think. Politicians see what is going to happen, and immediately act to prevent it, without thinking on the consequences of their actions, while Jennings is used to reverse-engineer everything, and as such, whenever he used the machine to see his future, and saw something bad was going on, he was able to think of a way to reverse it with small changes.
- Also, the changes caused by the politicians are at a very large scale, so they don't realize how much those changes can affect everything.
- It is really amazing that as intelligent a person as Jennings had to resort to the microfilm placed on a stamp to get to think of such a simple thing as "Whatever future this predicts, we make happen. We give over control of our lives completely." Did he think that the machine was intended to be used by Karma Houdinis like himself?
