I think SETI is really a waste for a completely different reason. And it's basically this: what should we do if we actually did find life out there? And the sensible answer is: hide. Seriously, the chance that contact with space aliens will bring us benifits is tiny. If they have the ability to visit us, then the far more likely scenario is that they will exploit/conquer us. You just have to look at our own history of contact between various cultures to figure that out. And in this case, it would be far worse, because the difference in technology, culture would be far greater than that between say, Europeans and indigenous people in North America/Australia.
So, is it sensible to spend money looking for creatures which if we find them, we should ignore? Better to spend the money figuring out how to hide!

The pragmatist in me says that SETI is a curious way for a few people to spend their time looking for signs of life 'somewhere out there' in the Universe, but it has no practical use.
I mean, honestly, let's assume that tomorrow, we capture a signal from an alien civilization. Finally, the answer to 'Are we alone in the Universe?' is answered, great. Then what? Chances are that the transmission is (by the time we received it) hundreds or thousands of years old. During that time, the civilization that sent it could have vanished for a number of reasons, of which we'd have no clue about.
If anything, such a discovery would only lead to more problems, since in one single swoop, a number of major religious beliefs would be shattered, therefore leaving a bunch of pissed-off fundamentalists in a tizzy. The best and brightest would be infinitely pleased with such a discovery, but unfortunately, they're a nearly insignificant minority compared to the idiot masses.
The bottom line is that if the SETI folks want to spend their time listening to space static or looking up at the stars, let them. It's their project, and if they can find the people to fund them, more power to them. If someday they find messages from 'little green/alien men', great.

Nothing. All the folks who say "a super advanced civilisation will have evolved beyond a need to eat us" are basing that view on absolutely nothing. If we ever find an advanced extra terrestrial civilisation, it will quite possibly be so alien as to boggle the mind, so making declarations about how they couldn't behave in some particular way is pretty dubious. The could literally be so alien that it may be impossible to ever really communicate with them. Aside from eating us, they may turn out to have a fondness for geometry, and decide to reshape our planet into a perfect sphere using quantum high energy death beams for purely aesthetic reasons.
The good news is that odds are quite good that we won't be both tasty and nutritious for aliens. The biochemistry would likely turn out to be really quite different. It's even possible that exposure to our atmosphere would be instantly toxic to them, making human hunting a bothersome affair which can only be done in a bulky and cumbersome space suit. Of course, being tasty would give them some reason to keep at least some of us around for breeding stock, so as it happens, being tasty might be a best-case scenario for humanity's long term survival!
But, in my own arbitrary guestimation, I'd expect that a really advanced civilisation would have relatively little interaction with us. There are probably nearer sources of minerals and water and whatnot than flying all the way to the sol system. They'll be so far ahead of us that we won't have any scientific information that intrigues them enough to come and steal it. If they have the sort of inclinations which would result in them wiping us out on contact, they probably would have done it to themselves before becoming so advanced. We'll probably only ever see them in person if they are interested in linguistics and anthropology and literature, etc.
As for the question of funding SETI, I don't think we'll find anything, but the potential payoff is worth the cost. Continuing with my arbitrary guesses, if there are advanced civilizations out there, they are talking to each other using either very directional signals which won't ever get to us. OR, they have invented some sort of sub space radio which is completely unknown to our understanding of the universe. In either case, we won't hear anything. What's worse, if you plug what I think are plausible guesses into the drake equation, any civilizations that are out there are probably very few, and very far away. But, there is still that chance of the biggest disovery in human history. I think that's worth something.

The same way you detect an intelligent civilization that does NOT use radio. You literally look for them. What if you took...

Given the technology, why couldn't we see if life exists elsewhere. I think we have a much better chance at finding a planet with oceans of green algae than one that watches TV.
Or, like I said, we travel in our own solar system and check here. There is much more life in the universe than intelligent life.
How long ago did Humans discover fire? When do you expect us to stop using it because we are "too advanced" ??
Not all at once, no. Currently, we use fire to heat water that turns turbines and produces electricity. It is inefficient and dirty. It is slowly being replaced by wind, solar and nuclear. So, eventually, we won't use fire to generate electricity.
We currently use fire to drive the internal combustion engine. Eventually, we'll all have electric cars (or something) that doesn't use fire to make it go.
Many years ago, we used fire to heat our homes. Many homes today use electric heat. GWBush's house uses geothermal heat to heat and cool his house.
So yeah, eventually fire will be replaced, one use at a time, and be seen and a naturally occurring menace.

This is true, but it's only because it's a binary solution set. Until or unless SETI finds a transmission, it will have made no progress in finding one, only in not finding one.
However, once it finds one, numerous benefits accrue; some certain, some with varying degrees of probability.
First of all, we learn that we're not alone, that we're not unique. Numerous modes of thinking posit that we are alone, or not, and those modes will receive solid underpinnings instead of speculation. This has general value for future inferences, even for current inferences where confirmation agrees. Like most of science, where this may lead may not be immediately obvious, but again like most of science, the odds are high that it will lead somewhere productive. And this consequence is certain. For instance, it would mean a great deal to me to have something I consider to be extremely likely but impossible for me to personally confirm, confirmed by objective facts.
Second, it will have identified one of two things for us: Either we have revealed a civilization that is just going through radio and is feeling pretty confident about itself and others, or it will have revealed a civilization that is much further along, and is interested in contact. The former would be a pretty huge co-incidence, because broadcast radio is inefficient (witness our going to cable to preserve bandwidth, optical to increase it, satellite to ground to bolster reliability and coverage, various beam methods like lasers and tight focus radio to save energy and achieve reliability), so the odds strongly favor the latter - the 100 year or so window we used broadcast radio is closing as we consider this today. So most likely, we'll have found life that is much further along than we are technologically, and looking for other life. It isn't a huge stretch to assume that such a find would come hand in hand with new technology for us. After all, if they want us to hear them, either they want to talk, or they want to get rid of us. It seems like a lot of work to try to get rid of things you don't even know are there, doesn't it? Inefficient. And it doesn't fit the mold... if they're worried about us, then letting us know they are there in such a way that they can't tell if we know or not is imprudent. So again, the odds fall on the side of life that can and is willing to benefit us.
Third (and we're getting lower on the probability scale here, but still) the transmission itself may contain immediately useful information for us. It could be anything. Make widgets like this. Don't go to the 3rd planet of Beta Centauri. Cut it out with the nukes, assholes. Efficient space drive drive works like so. Your Aishwara Rai, can we buy her? 42.
Lastly, and least likely, we could be handed a paradigm shift. Antigravity. FTL travel of any flavor. Additional physics. How to clean up our atmosphere. Things we cannot even vaguely imagine.
All of these things only require reception. If we add transmission back to a known source of an intelligent signal, now we're talking interaction. That could be wild as well.
There may be gold mines for linguistics; for biology; for physics and all the sciences that are really corners of physics (chem, electronics, nuclear, etc.)
And in the meantime, SETI does something else for us. It serves as a focal point for a certain type of hope, a bright optimism, that I would really rather not see go away.
So if you really want to cut funds, I suggest that the place to do it is in funding, oh, I don't know, how about a certain war in the middle east? Maybe quit funding the "drug war" against our own citizens? Either of those would benefit most people (not arms manufacturers or those in the jobs that have sprung up for our most recent go at prohibition, of course, but I guess I don't really give a darn about those particular people for some reason.)
