METI (Messaging to Extra-Terrestrial Intelligence) represents a cardinally new kind of human activity. Some argue that the Search for Extra-Terrestrial Intelligence (SETI) also is cardinally new. Yes, it is new, but not cardinally so, because people have always passively surveyed the heavens in the hope of detecting something unknown, whether natural or artificial. However, a purposeful effort directed toward converting terrestrial civilizations into the object of detection by possible extraterrestrial civilizations, which is the focus of METI, is a substantially new activity.
The scientific program known as SETI endeavors as its main goal to search for any kind of electromagnetic radiation from aliens. In contrast, METI's main goal is to create and to send intelligent messages from humans to aliens. SETI scientists sometimes ask whether Active SETI (as METI is sometimes called) makes sense. Would it be reasonable, in the context of ensuring SETI success, to transmit messages with the express intention of attracting ETI's attention, thus eliciting a response?
Although this question is a valid one, the overall goal of METI is much broader: to overcome the Great Silence in the Universe by conveying to ETI the long-awaited news: "You are not alone!" Indeed, since a basic tenet of SETI science is the tacit assumption that civilizations transmitting interstellar messages do indeed exist, the scientists who are involved in SETI should unavoidably accept that messaging to ETI is a reasonable and fully complementary activity.
