stinkymountain writes to tell us NetworkWorld's James Gaskin has an interesting take on Artificial Intelligence research and how the term AI is diverging from the actual implementation. "If you define artificial intelligence as self-aware, self-learning, mobile systems, then artificial intelligence has been a huge disappointment. On the other hand, every time you search the Web, get a movie recommendation from NetFlix, or speak to a telephone voice recognition system, tools developed chasing the great promise of intelligent machines do the work."

Heh, the first "computer" I built wasn't really a computer at all, but a Turing Test machine similar to your Apple II program which actually worked the same way, and was the basis for the "Artificial Insanity" program I wrote in 1983 (or was it 1984?).
I was in the 6th grade IIRC, and the "computer" started life as an "idiot finder". You would point it at a person, and if they were an idiot, a light on it would light up.
Actually it was a battery, a flashlight bulb, and a reed switch. I wore a ring with a magnet; to work I'd point it at the victim and move my ring by where the switch was. The other kids loved it, to them I was a nerdy legend.
The teachers hated it. To them I was a pest.
The next iteration had the bulb replaced by a motor, with the aformentioned answers printed out and rolled up. "Is the teacher an idiot?" "Whirrrrrr..."

I think AC has it right on the mark. "Intelligence" is apparently a world we use to describe computations we don't understand very well. At one point, the ability to using logic to perform a flexible sequence of calculations would have been considered "intelligence". As soon as it became common to replace payroll clerks with computers, it was no longer a form of intelligence.
We are not demonstrably closer no to reproducing (or hosting) human intelligence in a machine than we were thirty years ago. But that doesn't mean the field hasn't generated successes, its just that each success redefines the field. "True AI" has thus far been like the horizon: you can cover a lot of ground, but it doesn't get any closer.

As a consequence of this situation, the AI field simply raises the bar for itself every time it succeeds at something.

That's not the same. When there is a success made in any of the fields that you mention it remains part of that field. A solved part of that field. Every success made in AI is no longer AI, so there are no successes or progress made "within the field". It's quite a substantial difference when it comes down to the perception of the field.
Chess was considered the ultimate AI problem back in the 40s and 50s. When we knew little about the game and how to solve it, it seemed that intelligence must be required to solve it. Now that machines are better at chess than humans we've redefined as a problem that is susceptible to brute force. It is not considered a success in the AI field, just another refinement of what is not AI.

Maybe there isn't "Artificial Intelligence" as we think of it. Perhaps every problem can be reduced to brute force, algorithms, and data structures.

Re:They keep changing the definition (Score:5, Insightful)
There's an important distinction to be made here- AI has two basic sub-fields: strong AI and weak AI. Strong AI research (computers that think like humans) has been more or less abandoned because it doesn't have a lot of practical application, or at least it isn't worth the money that it will cost to create.
Weak AI research (pathfinding algorithms, problem solving, expert systems, etc) is very much alive and kicking- anti-spambots, anti-anti-spambots, malware, amazon.com's recommendation system, google's indexing, etc.
In fact, weak AI implementations are getting more and more common every day. It's pretty safe to say that we are already 'there', though there will certainly be more huge advances in the future.
In my opinion, the problem with strong AI research is that we are arbitrarily defining rules and expectations. For example, if we were to accurately model the physical world, all we'd have to do is set up a few evolutionary bots to learn about their environment, and give them a few billion generations.
However, just like we can't predict the paths that biological evolution will take, we have no guarantee that computer thinking will follow the same path that we will, (in fact, I would bet on it not following that path). Thus, 'Intelligence' in the simulated world would probably look nothing like we expect.
The problems here are questions of scale and our own understanding of physics. The physics problem first:
We're constantly redefining our understanding of the world. This is a good thing, but it makes it hard to model the world when the rules keep changing. If we were to program a 'matrix' for the AI program to develop in, there would be arbitrary rules that could not be broken. The program may find ways to circumvent them anyways (hacking its own world, essentially), but those solutions would not map to the 'real world', and would not be useful for creating programs that can interact with humans in that world.
As far as I can tell, you can't train AI software in a simulated world. It should be noted that the AI of systems that live their whole lives in the simulated world (MMORPGs come to mind) is actually very advanced. This brings me to the other issue-
You can train a program to interact in the human world, like IRC bots, search engine algorithms, etc. The problem here is that the humans have billions of years of built in programming. I'm fairly confident that if a human were to sit on IRC talking to a well-coded bot for a few billion years, that bot would be able to carry on a pretty good conversation, but the amount of time that we currently give those systems in their 'learning phase' is miniscule compared to the size of our own.
Interestingly, this is pretty much exactly what the computer system in 'The Hitchiker's Guide' does.

Actually, I detest them, but I do think there is a lot of untapped research potential there, because of the sheer number of people who are willing to sit there for hours on end, waiting for npcs to respawn. With a good learning algorithm and enough entropy (causing 'genetic mutations'), those npcs will eventually find a few optimal ways to react to their environments, prolonging their own lives. They just need people to coach them through it.
With that many users, you'd get enough variation between the newb that's killing them for experience to the maxed-out-character that blows up everything in his way.

Indeed, there was a time when binary search trees were called "artificial intelligence".
Remember that program to catalogue animals? It started with something like "Is it a dog?", then you say no, and since the database is seeded with only one animal, it would respond with "I don't know the animal, what is it?" ("a bird"). Then it would ask what question would make the difference between the two clear ("Does it fly?"), and next time you run the program, it starts with "Does it fly?". If you say yes, it would ask "Is it a bird?" and so on, and so on.

This is a form of emergent behavior that is not present in computer programs. Even the best AI has difficulty emerging new abilities and demonstrating independent thinking. Sure, I can stick a genetic algorithm or a Bayesian filter on a problem, but it will never demonstrate behaviors above and beyond the problem space it's given. These sorts of algorithms may be a key piece of artificial intelligence, but we're still missing the secret ingredient that gives animals their own identity and ability to adapt and learn.
Turing gave us the litmus test decades ago. While the full Turing Test may be far beyond us right now, it at least teaches us the types of behaviors we're looking for when attempting to create an intelligent machine. When even the creators of the machine are surprised by certain behaviors, THEN we will be getting close. :-)

Necessary advances in understanding... (Score:5, Insightful)
... 'intelligence' need to be made first. I have a feeling that the reason AI has 'underdelivered' is merely due to not understanding our own intelligence first. I think the whole idea that AI's we imagine (like in the movies) could be constructed purely de-novo, was naive. I think it's a matter of cross-polination that has to take place from biology and many other sciences, some genius's and teams of scientists have to come along and take all the elements and put them together into a cohesive framework.
Re:Necessary advances in understanding... (Score:5, Interesting)
This is the primary point I came in here to say. Whenever I've read anything about AI, it seems to be based on cool science-fictiony ideas, or else it's actually a simpler method to use statistical analysis to approximate human decision-making for particular purposes. If you're talking about real self-aware thinking things, the approaches are all wrong.
People tend to act treat the subject as though dumping enough raw information into a fast enough processor will yield intelligence, and then as that intelligence grows and develops, things like "sensible responses to answers" or "appropriate emotional responses" will emerge. Or else they think grouping enough "appropriate responses" will eventually yield intelligence.
It seems to me that that's all backwards. If you want to design an artificial intelligence, you first need a good philosophical understanding of how intelligence works, which will tell you straight-off something that AI researchers don't seem to consider: intelligence is an animal trait.
I think the absolute first thing you need to do is to figure out how to give machines emotions, to approximate pleasure/desire and pain/aversion. The second thing you need to do is give it "senses", and the ability to draw a very basic sensory conception of its world based on those senses, which includes a sense of time and objects. Also, you'll have to give it the ability to interact with its world in such a way that it is able to pursue its desires, encounter obstacles, and experience "pain". Finally, you'll have to figure out a way to give it the ability to adapt, to "rewrite its programing", preferably in a way that allows it to reproduce and evolve.
So in a way, the most obvious answer is that if you want an artificial intelligence, you'll have to design an artificial/virtual animal and place it into an environment where it can evolve intelligence. There may be some shortcuts on growing/evolving it faster, but you shouldn't be quick to discount the animal nature of intelligence as we know it.
And the reason for these things are bound up with the fact that, like I said, the only model for real intelligence we have to base anything on is animal intelligence. Animals develop and express their intelligence by being self-motivated in a world that presents obstacles. If there's nothing you want, there's no point in figuring anything out. If there's no way to get what you want, then there's no point in figuring things out. If there are no obstacles in your way, then there's nothing to figure out.
So if you don't have a self-motivated desire and the ability to move towards achieving that desire, then you can't make self-determined intelligent decisions. If course, this also presents a scary twist to the whole AI thing, because it suggests one of the chief scifi fears of AI will turn out to be correct: If we're successful in creating AI, we may not be able to control it.

That's basically the "scruffy" approach to AI, as opposed the "neat" approach, which was to define all the supposed rules that people supposedly follow. There was always a competition between the "scruffies", who thought that neural nets, genetic algorithms, and bayesian nets would enable us to "grow brains in a box" that would eventually be complex enough to think like we do, and the "neats" who could never define all the rules, because they relied on question-answer sessions with the "thinkers" who often thought they were following rules, but often turned out to be using instincts and assumptions that they never consciously thought about.
I was working in an AI research company back in the late 80's, and I remember the fun and "fun" we had back then. I tend to fall more in the "scruffy" category, but I'm coming from an implementation rather than research background, and I saw all the problems with the rule-based approaches. Even getting good probabilities from "experts" concerning their decisions and evaluations, to feed into Bayesian probability nets, was nearly impossible.

If you can represent a complex problem in a simple fashion, then even incremental improvements can produce large quality/efficiency improvements.
If you're looking for AI disciplines producing work with layman-notable results that are not as clearly search- or planning-based, natural language processing (NLP) and computer vision have both been quite hot over the past five years.

Machine Learning however, seeks to simply mimic human behavior, just to recognize patterns and make decisions, but not become sentient.
Additionally, Machine Learning often concentrates on one problem (OCR, internet search, etc.) rather than a truly self-aware entity that has to deal with a variety of tasks.
At least that's how I describe my field to people not familiar with it. They've usually heard of AI, so it's a good stepping stone to helping them understand what I do.

Up until the Grand Challenge, robotics R&D had been done by small research groups under no pressure to produce working systems. Most systems were one-offs that were never deployed. DARPA figured out how to get results. There was a carrot (the $2 million prize), and a stick (universities that didn't get results risked having their DARPA funding for robotics cut off.)
The other big result from the DARPA Grand Challenge was that robotics projects became much larger. Nobody had 50-100 people on a robotics R&D project until then (well, maybe Honda). Robotics projects used to be a professor and 2 or 3 grad students. Suddenly stuff was getting done faster.
DoD started pushing harder. Robots like Big Dog got enough money to be forced through to working systems. Little tracked machines were going to battlefields in quantity, and enough engineering effort was put into mechanical reliability to make the things really work.
CPU power helped. Texture-based vision now works. Vision-based SLAM went from a 2D algorithm that sometimes worked indoors to a solid technology that worked outdoors. Much of early vision processing is now done in GPUs, which are just right for doing dumb local operations like convolution in bulk. GPS and inertial hardware got better and cheaper.
