To suggest finding nothing is somehow interesting enough to warrant the yearly cost of SETI is internally contradictory.
In nearly six decades of listening, we've not heard a single thing which would suggest any life form capable of transmitting information detectable b ...[text shortened]... ction.
Sixty years of nothing.
The only thing learned from that is man's general stupidity.
It's a big galaxy and a bigger universe and we know if OUR equipment was on the other side of our galaxy we could hear it if the signals traveled to us in time for us to hear it.
So far we have only scratched the barest surface of the stars out there and have come up empty.
The thing is, a negative just shows how big a volume we need to cover to have a chance at an alien signal.
Of course there may NEVER be a signal but maybe that would suggest there is only one high tech culture in a typical galaxy at a time, so maybe a billion years ago there was one but of course any signals from that bunch would have gone way of of the galaxy and no longer be present to be detected at all or maybe the next high tech culture comes about 100 million years from now. Either case we find nothing.
That is still usefull information, at least it would say we wouldn't have to fear much some hostile alien space navy coming to Earth to decimate us.
But if we actually DO detect some proven alien signal, that would be VERY big news, saying we are not alone in the universe and it would say perhaps at least there is room for 2 high tech cultures in the same galaxy suggesting there may be 2 in Andromeda galaxy and 2 in the Sombrero galaxy and so forth.
It is still an interesting pursuit because you never know when a development will have some major discovery, perhaps curing cancer, perhaps eliminating war, whatever.
Just saying we don't know where ANY research will lead so there is room for all kinds of real research.
