Robograding?

I read the outline of an article on the idea of robograding which means using machine programmed intelligence to grade papers. It explained what robograding meant to imply and then it talked about why it is so far away from being realized. I remember when early adoption of computers in the classroom led to some believing they would eliminate teachers and I retorted that there would always be a need for teachers. Same thing applies with this concept. We can program machines to mark simple examples where there is no thinking involved, only choices. But as soon as thinking which means emotions become involved, it is much harder to do in the best interests of the students. Only a good teacher can see into the mind and thinking of a student and it is in that in between place where sometimes we have to assess fairly what a student is trying to say and show.
