Deep learning can expose hidden non-linear relationships in the data. It's state-of-the-art in applications such as object recognition from images and voice recognition. There have also been promising results in the natural language processing field. What all of these have in common is that they are "real" artificial intelligence, i.e. teaching computers things that they have been historically bad at compared to humans. Search for a talk by Geoffrey Hinton if you are genuinely interested.
