The knowledge and technology to be gained from interaction with extraterrestrials is potentially limitless:  Humanity has built, in the relatively few millennia since formal writing was invented, compiled a truly gigantic quantity of information and knowledge, to which it is constantly adding, at increasingly rapid rates. To imagine the treasure trove of knowledge and experience that would become available to humanity in the event of contact with intelligent extraterrestrial life of similar, or even greater, technological and social development is almost impossible1. The wisdom that could be gained, especially considering that alien life would likely have evolved along very different lines than humans, could be of a kind that mankind could never have conceived without such contact. This great potential for the gaining of knowledge is reason enough to devote resources to the effort of making contact. 1 Sagan, Carl. 1973. Communication with Extraterrestrial Intelligence.
