> prediction doesn't and can't contain information (in the technical sense) from the future, since by definition it's based only on what we know in the present In the technical sense the future _is_ driven purely by the information available in the present. It’s a function of t-1. The only reason future should be different from prediction is if the set of information available to the predictor about the present is different from the actual set of information about the present.
