What we actually have though are thousands (potentially millions) of well-fed human brains which are volunteering their downtime in a particular moment of their life to receive factual information of any kind (of the kind they expect to see on Wikipedia) in the hopes of getting something good. A system that chose the best possible article to present to them in that moment to bend the course of their life in a good direction or satisfy some need (or attempt/pretend to satisfy, as much as we can by shooting photons at their retinas) would be a better engineered system than one that randomly selects from its entire catalog of options correctly and efficiently.
