"Google's mission is to organize the world's information and make it universally accessible and useful." -- About Google
Google is the most powerful nonhuman teacher ever known to actual humans. Implicitly and ceaselessly, Google performs formative assessments by collecting the following data: the content, genre and media that interests you most; when and for how long you access your external cloud brain; what your hobbies and routines are; with whom you work and communicate; who will get your November vote; and whether you prefer invigorating clean mint or enamel renewal toothpaste. By continuously refining the nuance of your sociogram, Google has already customized your next web exploration and taught itself to teach.
