Predictions

Can we make useful and reliable predications about future events? First yes we can make predictions, we do it all the time for ourselves. So called experts make predictions too, should we listen to them? More importantly should we act on them? Useful predictions are one thing, what is useful? Reliable is another thing. How reliable can our predictions be? What about the Black Swans? Those unpredictable events that change everything. Is the world understandable by humans to a degree that would allow us to make reliable and useful predictions? Or is the world (universe) too complicated for us to understand to a level that would allow us to make useful and reliable predictions? I predict I will drive to work tomorrow and spend the day aggregating and correlating useless information that I will use to make predictions. Will any of them be useful or reliable?
