Nothing to Do in the Future

In a future where everything is fulfilled, a man uses his mother's death to design a mystery for himself that can never be solved, because only in pursuing it can he escape the freedom of having nothing to do. This is not a "beat the system" story. This is a story of "living with the system because the system is you". The protagonist's victory is not liberation, but acceptance; it is not the truth coming to light, it is living with the mystery; it is not "I am free", it is "I know I am in a cage, and I made the cage." In a future with nothing to do, perhaps the last thing to do is: know you have nothing to do, but continue.
