the FAA has issued hundreds of certificates to police and other government agencies [...] to allow them to fly drones over the United States
Cleaning this up is part of the FAA Reauthorization bill that Obama is signing. The FAA is being tasked to integrate unmanned flight into the national airspace system.
At the moment, each flight must have either a ground spotter or a chase plane in order to provide the see-and-avoid capability that is a requirement for all flights in visual conditions.
One reason I am not as pessimistic as some others is that the private pilot brigade, through AOPA and others, is extremely political and vocal. To generalise, they epitomise the self-reliant, freedom characteristics often associated with America.
There is no way they are going to accept that their freedom to fly wherever they want is being restricted just to accommodate drones. Expect an increasingly vocal campaign over the next several years.

Then I saw our government is already using them against us. This is sad.
Renoir's 1937 film La Grande Illusion, beautifully illustrated how those on the other side of battle lines often have more in common with you than you think and those on the same side may not share your interests.
I have no problem with the average Joe on the street in the middle east, yet he is being harmed with my tax money. I have a big problem with someone spying on a peaceful protest near my home.
EDIT: resolved ambiguity someone responded to. I have no problem with the average Joe. I do have a problem with him being harmed with my tax money. Sorry for any confusion.
Really? It's quite amazing to be able to say this after having said that "those on the other side of battle lines often have more in common with you than you think".
How do you think "the average Joe on the street in the middle east" feels about having an unmanned plane over his head? How do you think his children feel when they see him being killed by such a machine? They swear they will seek vengeance.
You will have only yourself to blame for this.
If we could find some consumer uses for robotics, the tech will evolve even faster.
At the end of the day, it's about finding the money to pay for the advances.
Another sixty years won't change that.
That's why all the smart money is in biotech -- because that might show more promise. A computer with a synthetic mind made out of living neurons might be more promising.
Anyhow, that's an expert system, not really an AI.
I know because I associate with cyberneticists, software engineers and biologists who have made this their life's work and who are engaged on this day in, day out.
Truly independent strong AI's are a pipe dream. At least for now. And merely throwing money at the problem won't by itself solve that. Digital computers as we know them and by themselves will not give us what we want. And why it is IMPERATIVE that AIs must be Asimov machines or at least can recognise friend or foe ... or else we are all in big trouble. The facts are we have nothing like this, nor does it seem anything too promising in that direction. Even humans aren't all that good at it if the stories of "friendly fire" are anything to go by. But I suppose you are saying "collateral damage" is a worthwhile price to pay for trying to develop AI's? Try explaining that on the six-o'clock news when a "safe" prototype AI drone malfunctions in a city full of your own people. Or even in a battlefield scenario.
I suggest you read the work of people like Blay Whitby and Kyran Dale (University of Sussex School of Cognitive and computing Sciences) for some practical background.
And where do you get the notion that digital machines can't be self-aware? What, exactly, are you basing this theory on? Are you claiming that some form of quantum state is required, or are you saying that intelligence needs to be analog?
"Intelligence" is neither digital or analogue (or maybe its a quantum artifact) -- we don't have a clue what it is. That's the point. It appears to be an emergent property of organic systems that must evolve over the development of that system but we still can't prove that we are intelligent or self-aware. But we can be certain it doesn't appear in purely deterministic machines who's every parameter can be assessed at the fine grain level.
Clearly there's no theoretical difficulty; with a large enough lookup table you could simulate every action an individual could take. Whether this lookup table can be considered conscious is academic if we have no way of defining consciousness.
So the question becomes: is there a more efficient algorithm that can be executed by a machine that it is feasible to build?
Because you're apparently certain that there isn't, you must have a mathematical proof that this algorithm cannot exist, right?
And even if your "certainty" was merely hyperbole, perhaps in lieu of proof you could provide some compelling evidence of your case?
Oh dear. That's Artificial Intelligence Day 1. It also doesn't work. That isn't an AI. There's also the slight dual problems of Nyquist and Shannon limits which dictate why this can't physically work in a digital system. But never mind. You seem to know that it is possible and it that's how to do it. No amount of prior research since 1948 onwards will be of any use to you.
You already have the answer. Its all just a matter of brute-force computing power and nothing else. Its that unsubtle, is it? Geee -- what a waste of time! All these years and it was just a matter of a big enough look up table. What a fool everyone has been not to just realise that!
So c'mon then, where is your fully functional robotic AI? Keeping it a secret isn't fair to the rest of us.
Did you consider any of these:

And this one's a doozy: http://works.bepress.com/cgi/viewcontent.cgi?filename=0&...
And they're just scratching the surface of a very deep field of research.
I don't know why you think this statement doesn't apply to humans. We're deterministic machines as well. More complicated perhaps, and less is known about the "fine grain level", but there is no evidence that we are anything more than complicated meat machines.
Humans are machines. But we (and other living things) appear to exhibit defined properties that are not present in complex digital machines. It also seems that what we refer to as self-awareness is an emergent property that living things have, although in theory, not specifically limited to living things.
That set of properties is what is formally defined as having a mind. Whatever that means, and I agree its far from clear what that is.
But -- and its a big but -- digital processes don't seem to be able to mimic or model it (that could be our shortcoming -- the models are not any good) and it isn't just a matter of more memory/processing power/a big enough look-up table. These are not the problem nor the answer. It isn't just a CompSci issue. If it were just that, we would have it licked by now and we would all have interchangeable minds that we could simply reprogram and upload with new sets of skills and belief systems (yes, Robots would definitely need them too, by the way).
We have a long way to go and for a while now we've been heading down the wrong road. But don't take my word for it.

He makes a distinction between subjective understanding of consciousness ("What is it like to be X?") and the objective understanding (What are the atoms and neurons doing? What is the structure of the mind?) I think this distinction is a big part of why you, and society as a whole, dismisses AI.
We have a much deeper objective understanding of computers than we do about our own brains. But comparatively, bats are as familiar as our own siblings next to our subjective understanding of "what it is like" to be a computer. We simply have no basis for comparison. We can't put ourselves in a computer's shoes. And without this subjective, gut feeling comparison, people in general find it difficult or impossible to assign the word "intelligence" to any non-humanoid entity, be it whales, robots, or computers.
I also am a great believer in things being more than just the sum of their parts -- or at least to have that potential. I just don't believe there are any sentient machines. Yet. And I'm not going to waste my time anthropomorphising them.
Because that's not going to make them happen any sooner.
My understanding is that most drones are remotely controlled by human pilots/personnel. I saw a documentary about this and they seemed pretty dumb compared with military tech from the 80s such as cruise missiles.
I'm sure that they are working on AI controlled drones but I'm pretty sure none of them are autonomous yet. They would have to be Asimov machines to some extent to prevent them from doing bad stuff to allies and friends or even their owners.
No robot AI combo to my knowledge is yet safe or reliable enough to be deployed on their own unsupervised. If they think that they are then, boy, are they going to get their asses kicked sooner or later when they inevitably malfunction.
The key word is optionally piloted http://bayourenaissanceman.blogspot.com/2011/05/more-about-f...
Early autopilots were analogue and worked remarkably well. Drones can keep flying and gliding without help (as long as they have power and fuel) -- of course they can. Its a classic and ancient application. But right now that makes them one step above a paper dart -- all be it with weaponry and reconnaissance. And that don't work without human intervention.
They are merely a remote extension of their human pilot's hand. Thankfully, because no one wants an autonomous drone going off on its own to "discover itself".

As an example, the US Navy's X-47B UCAS-D demonstrator has already demonstrated autonomous flight, but the USN plans to test autonomous carrier landings at sea sometime next year with fully-autonomous aerial refuelling the year after that.
The thing is, autonomous flight isn't that difficult and the technology for it has been in place for some time. Where complications arise is with bad weather, which can confuse an aircraft's sensors; situations where precision instrument approaches aren't available and, most importantly, other aircraft. There is still not complete certainty that it's safe to fly an autonomous UAV in congested airspace where other other pilots often do unexpected things.
Many of these issues can be solved by technical means alone, including the ability to monitor, anticipate and avoid other aircraft. But we're still a very long way from solving that fuzzy boundary when things go wrong and only human judgement can prevent disaster.
I also do not believe that aircraft like the X-47B will be given autonomous freedom to select their own targets when they are deployed in about a decade. Instead, while they'll fly autonomously, their targets will be selected by human operators who'll also authorise the release of weapons.
True autonomy is going to require the answering of plenty of technical and ethical questions.
Precisely my point. Thanks. We all know flight autonomy is already here. Has been for ages.
The aerial refuelling is a neat trick which I'm not convinced will be able to be taken for granted yet -- I can see this won't become fully autonomous for a while. That procedure would have to be completely predictable and reliable -- at least as reliable as a human-managed manoeuvre and that isn't without risk.
As for aerial refuelling, I think autonomous probe & drogue refuelling is definitely feasible. They've already proven the ability of the X-47B's flight systems to maintain the refuelling position behind a 707, which is technically one of the harder things to get right.
One of the reasons aerial refuelling is so tricky is that it requires constant rapid adjustments by the pilot in the receiving aircraft to stay in position while receiving fuel. The X-47B should be able to process those adjustments much faster than a human pilot.
