An estimate says that there at least 361 intelligent civilizations in our galaxy and possibly as many as 38,000. I wonder how many of these inhabited worleds are cut up into arbitrary borders with nations bombing each other to get at fossil fuels. At any rate, I keep hoping we'll discover such a civilization in my lifetime. I think it would have a profound affect on our thinking. The odds are that anyone we discovered would be vastly smarter than us and hopefully much wiser.
