Who can really say until we know how this system works? I mean, everyone knows that spellcheckers aren’t always right because they don’t understand context, so how will this computerized grader know how to go behind grading usage and mechanics. A good essay involves so much more than that and I don’t know how a computer can understand smooth transitions or a clever turn of phrase.
Students love to gripe about how long teachers take with grades but instantaneous is too quick. How can an essay be properly graded so speedily? This is not a math problem that has only right answer. Also, how can the feedback a computer gives match the carefully considered comments a teacher leaves in the margins or at the end of your paper? I very much doubt that a computer analyzing my use of grammar will make me feel warm and fuzzy the way my english teacher writing “a pleasurable read” or “interesting and effective” does.
Silas Beane and colleagues at the University of Bonn in Germany considered other testable deviations along these lines (including some anomalous behaviour by the electron’s heavier cousin, the muon). However, there are several possible ways their scheme won’t work. Whoever wrote the simulation might not use the same type of code nuclear physicists do, meaning that the predicted deviations won’t show up. The deviation might also happen at such high energies that we won’t discover them in the foreseeable future. Lastly, spacetime might behave like a lattice for reasons other than living in a simulation, a possibility seriously considered by a number of physicists.
