This is a story about a man and his hopelessness. He is firmly convinced that knowledge is the key to everything. But every time he thinks that he has almost solved the problem, new inputs, new errors appear. His madness is endless. He has been in a confined space for many years, he has lost track of time, but this is not what worries him. The main thing is to solve the problem. Time after time, he starts all over again and cannot finish it. And it is always a path from hopelessness to deceptive triumph and again to hopelessness. This is a vicious circle that he cannot leave. Knowledge is the key.
