So are you saying that we should do as little as possible? And to ensure just that, we should have stayed ignorant as long as possible?
Well, if the message IS true, we WILL go extinct no matter WHAT we do. It doesn't sound appealing to me to know exactly when and how you're going to die. So if nothing can prevent it anyway, I'd rather not know.
If the message is a joke, then it is obviously unnecessary to let it have any influence.
