Critical precision in grading is only necessary in competitive high-stakes academic environments where everyone is striving for excellence (or at least a shot at belonging to the social or technical elite). If you consider an environment where the point is simply to train a crowd of semi-skilled workers to a level of basic white-collar functionality (which is what most mid- to lower-tier colleges are approaching, and what MOOCs will probably become), widespread use of this technology becomes much more plausible and acceptable.
