It’s about 15 or so years ago I tried Prolog in an application for analyzing features of images. I remember two things from that – 1. Even though concurrency is elegantly described through guards, implementation turned out to to be not that easy, 2. You have to bypass the beauty of pure logical statements in practice (for example see the 'Craft of Prolog' by Richard O'Keefe on optimizing Prolog code). Once we get to this level of writing Prolog code, you find other standard languages and libraries more competitive and practical.
