I've occasionally came across some thought of this large metaphor which search engines are in.
Human race since the beginning of times, tried to find answers, to their inquietude and with it, go further.
So it makes the web based search engines, the human extensions means to get the answers, of such unsatisfactory endless search.
Actually someone could name search engines, Dissatisfaction Repository (DIREP) .... not quite appealing though.... 😏.
