Gotcha. No practical use of your work. You're like those pure mathematicians who just do math for the sake of math. I don't see a problem with that, it's just amusing you're trying to compare your field with deep learning. I'm a researcher too - I look for ways to build faster hardware for deep learning. But to answer your question - using deep learning I can classify objects, recognize speech, and translate language, as well as generate plausible text, nice sounding music, or beautiful pictures. Those are just few examples of what I can do with DL much better than with any other methods.
