I sometimes in the past have wondered how boring it must be to grade papers that all follow the exact same patterns... But I must admit I didn't think we were quite that close to having software that can grade papers...
(It's worth pointing out that this program apparently only supplements human grading, to give student feedback before handing the paper in, and to help the academic staff get a quick assessment so they can focus on detail).
I'd really love seeing a proper paper on the accuracy compared to having the same set of papers graded by different humans.
