Then again, Mr. Perelman wrote the essay in less than one second, using the Basic Automatic B.S. Essay Language Generator, or Babel, a new piece of weaponry in his continuing war on automated essay-grading software.

For this essay, Mr. Perelman has entered only one keyword: "privacy." With the click of a button, the program produced a string of bloated sentences that, though grammatically correct and structurally sound, have no coherent meaning. Not to humans, anyway. But Mr. Perelman is not trying to impress humans. He is trying to fool machines...

Mr. Perelman’s fundamental problem with essay-grading automatons, he explains, is that they "are not measuring any of the real constructs that have to do with writing." They cannot read meaning, and they cannot check facts. More to the point, they cannot tell gibberish from lucid writing.
