Yeah, were finding many more planets, but it's bewildering how many more ways they can turn out unpleasant than may have been appreciated in the early 80s when Sagan (and others) were discussing odds and probabilities of all this.
Something does not even have to "go wrong." There could be another planet a few light years away which developed intelligent life exactly as we did but started 200 years later. For them it is 1817. How exactly would they pick up our radio waves? How would they transmit them so we could hear them? For all we know there could be planets around younger stars who are just now reaching the Homo Erectus stage. Let's hope for their sake that they get it right this time and skip all the stupid god shit.
