NASA has had some projects to try to notify ETs of our presence on Earth. AFAIK they’re still doing it? They should have asked transhumanists what the expected value of being contacted by ET is.
People are still doing it, not NASA though. Their rationalizations can get pretty funny. It seems stupid but rather harmless; it’s hard to find a set of assumptions under which there’s a nontrivial probability that it matters.
