there'll always be idiots (Score 1)

I guess there'll always be idiots unless all 'advanced' civilisations 'out there' espouse eugenics and/or other self-limiting technologies. Religious beliefs also seem to be strangely resistant to logic.

So we might have expected a constant stream of idiots and religious nutters, from far away/the future/another dimension/angelic realms. Add to their numbers those utterly dull people interested in their genealogy (code for a ridiculous and pathetic search for an ancestor who actually did something 'unusual'; for example, being transported to Australia, inheriting a title, making a pile of money, or any other of the shabby claims to distinction our enfeebled moderns grasp at) and we should have been overwhelmed by visitors from the vasty depths of space and time, despite the very doubtful premise that in the future we will be much, much cleverer than we we are now, and, by analogy, so will be/are these posited 'aliens' who aren’t visiting.

On the other hand, maybe they are so sophisticated that they would no more consider introducing themselves to us individually, or even collectively, than the child with an ant farm bothers to make the acquaintance of the ants that make up her colony.

But if we leave aside the silly stuff and reflect upon the truly amazing size of the universe and the relative rigidity of the rules which seem to govern it, it doesn’t seem quite so strange that, so far, no one has called on us...
