[space] Greetings, E.T. (Please Don’t Murder Us) … Steven Johnson on the Pros and Cons of attempting to contact Extraterrestrial Civilizations. ‘Drake leaned forward, nodding. “It raises a very interesting, nonscientific question, which is: Are extraterrestrial civilizations altruistic? Do they recognize this problem and establish a beacon for the benefit of the other folks out there? My answer is: I think it’s actually Darwinian; I think evolution favors altruistic societies. So my guess is yes. And that means there might be one powerful signal for each civilization.” Given the transit time across the universe, that signal might well outlast us as a species, in which case it might ultimately serve as a memorial as much as a message, like an interstellar version of the Great Pyramids: proof that a technologically advanced organism evolved on this planet, whatever that organism’s ultimate fate.’
