The closest thing I've seen is virtual drummers in Logic X which will follow along with the structure of your song and generate a percussive accompaniment. It's no substitute for a real drummer but it's serviceable.

No real clue how someone would use them for a more serious endeavor, only thing I could imagine would be to quickly iterate/prototype with song structures on a fixed seed to generate ideas for a real composition. Consider the case of an indie game developer or film maker getting some placeholder music to test the experience during early throwaway iterations.
