Wolfram | Alpha predicts from the previous human input, I am getting "Assuming 'the future' is a song" on request "What is the future". But even kids are better than Wolfram in answering such a question. They can tell you that the future is a grammatical tense used for expression about things that will or can happen.

And from this limitations of the predictive interface are clear. If it does not have enough candidates, it will bring user nothing but weak excuse.
