I agree but my conclusion based on this is that, for the foreseeable future, we'll need hybrid systems that can merge expert knowledge with machine learning.<p>In the coming weeks there will be a lot of hand-wringing about Watson's performance on Jeopardy and what it means for humanity and jobs and so on.. I think it's important to remember that the last mile in many tasks will still require humans and that AI should be seen more as human augmentation rather than replacement.
