I think you are thinking of solomonoff induction, AIXI won't answer your questions unless it has the goal of getting reward from you for answering the question. It will do what it predicts will get it reward, not try and output the end of all strings given to it. "I propose prediction as a general test of understanding. For example, do you understand the sequence 0101010101010101 ? If I asked you to predict the next bit and you did so correctly, then I would say you understand it." What would happen if I said, "I don't have time for silly games, please stop emailing me". Would you consider that I understood it? "If I want to test your understanding of X, I can describe X, give you part of the description, and test if you can predict the rest. If I want to test if you understand a picture, I can cover part of it and ask you to predict what might be there." This only works if my goal includes revealing my understanding to you.
