Advertisers don't get to control who sees their ads; they don't even have much capability to target specific demographics. Instead, they rely on Google to do the targeting which works well because (a) Google is better at it then advertisers would be anyway, (b) advertisers don't pay except when the user clicks (speaking of adwords here; there's also a smaller display ads business which works differently, but without giving advertisers more information or control) and (c) Google provides advertisers with great tools to determine their return on advertising investment. (c) is really what has made Google the powerhouse in this space: by allowing advertisers to see exactly how effective their ad campaigns are or are not, Google solved one of the oldest problems in advertising, the "I know half of my advertising budget is working, I just don't know which half" problem.

    i hope we can agree that the whole singularity notion that because of some unscientific conjecture about processor speed that 'ai' is predictable is nonsense...

    I agree that processor speed has little if anything to do with it. It's clearly about software. If it were about speed only, then we should, right now, be able to build an artificial intelligence that runs very slowly. Perhaps it would think at a millionth of the speed of a human brain, but the processes of creative thinking would still be recognizable as such. Then we could know that we just need a computer a million times faster to match a human brain, and that further performance improvements would surpass the human brain.

    But we don't know how to create an AI running at any speed, because we don't understand how intelligence works.

    look, even in this far-flung, completely fictional but theoretically possible scenario, the Commander Data is so complex that in the fictional narrative, the character is depicted as being impossible to re-create...virtually impossible anyway

    Yes, that is clearly fiction: If we have the knowledge necessary to create intelligence, there's no reason at all to suppose that we will only be able to do it once. That would imply that we didn't really know how we did it. Technological advances almost never precede the understanding of their function. It's the other way around. In fact, that is the reason AI research in the past has traditionally failed: We hoped that we could create intelligence prior to actually understanding how it works. my point you have to reach beyond any possible logic to pure fiction, where it all kind of breaks down

    You're assuming your own conclusion, AKA begging the question. You're assuming that AI could only exist in pure fiction, and using that assumption to argue that AI could only exist in pure fiction.

    i have to admit that theoretically the human mind works and is a system and therefore can (and this is very far-flung...pure conjecture) be constructed

    Yes, the human mind works and is a system... but why is it such a far-flung conjecture to assume it can be constructed? It is constructed, every day, via reproducible physical processes. It is not a "far-flung" conjecture to consider that it could be constructed via a different mechanism, or from different materials, on the contrary it is a "far-flung" conjecture to suppose that it cannot, because that would imply that in some way human brains violate the laws of physics, or at least rely on some physical processes that are impossibly specific.

    For example -- and note that I'm not implying that this is the best, or most efficient way to accomplish it, in fact I'm quite certain it is not -- imagine a traditional computer running a fully-detailed simulation of a human brain. This simulation is an exact replica of a real human brain, and simulates every neuron, every chemical reaction, etc. It even simulates the quantum uncertainty effects at the finest level of detail.

    Why would that simulation not evince "free will" (whatever that is)? Even if it did so with agonizing slowness. Unless you can conjecture some reason why it would not be able to think, then you must suppose that thinking machines can take on other forms. Further, there's no reason to expect that the "hardware" of brains, the specific structure of neurons and neurotransmitters, is inherently required to carry out thought. Information processing can be carried out in a bewildering variety of ways, all of which produce exactly the same results. This means that we should also be able to create thought by implementing the same information flows in other physical systems, without resorting to simulating the physical system of the brain.

    Unless, of course, there is some element of human thought, or free will, or whatever you'd like to call it, that indeed does not derive from physics. Something supernatural.

  12. Re:Some realistic space battles in literature on The Physics of Space Battles · · Score: 2

    David Weber's approach for the Honor Harrington series is pretty good.

    In order to make somewhat realistic space battles interesting (or even possible), he postulates "inertial sump" technology as well as gravitic drives which combined make possible ship accelerations measured in 100s of gravities, and missile accelerations measured in tens of thousands of gravities. Even with those incredible accelerations, he makes the point that the tactical opportunities provided by being able to navigate in three dimensions make it very hard to make an enemy fight if decides to run. So a great deal of strategy goes into manipulating an enemy into a position where he can't run (e.g. because he has to defend a fixed objective) or getting him to build a vector that brings him inevitably into range of your force because his maximum acceleration on any vector isn't enough to clear your missile range. Oh, and at the incredible speeds obtained (up to ~0.5c; inadequate "particle shielding" generally prevents higher velocities), passing engagements are over incredibly quickly, so you really need to match vectors fairly closely to have any sort of a slugging match.

    The result is reasonably realistic, and also makes for interesting, dramatic battles. Only "reasonably" realistic, though, because Weber never explores the full implications of the gravitic technology. If you think too hard about the implications of those, you quickly realize that the fictional society is utterly ignoring 99% of the potential of either their gravitics or their power plants, or both. In that it's something like the transporters and food replicators of Star Trek, though not quite as severe. But ignoring that, Weber's physics are believable and set the stage for entertaining drama.

    For fans of sail-age nautical warfare, Weber also manages to construct a scenario where many of the dynamics of wet-navy combat carry over, including, at the beginning at least, the use of the "line of battle", except that in 3D it becomes a "wall of battle". So rather than "ships of the line", you have "ships of the wall". Anyway, it all comes together pretty well.

    Oh, and he tells a good story, too.

What, fundamentally, is special about the computations in human brains that constitute "free will" that makes it impossible to replicate them in different hardware?

    Yes and no.

    I agree that it's likely that there's no specific line, at least not a sharp one, but there is a qualitative difference between machine learning as we know it now, and human learning. Human learning, at least the best human learning, is about the creation of knowledge, not the acquisition of facts, nor even the identification of key facts from a larger mass (which is what machine learning as done today is about).

    A key difference is explanation. A human playing Breakout not only comes up with the strategy of tunneling and exploiting it to knock out lots of blocks from the top, but can explain why that strategy works. This sort of meta-learning, knowledge plus understanding of knowledge, is something that none of our algorithms can yet implement.

    every human is unique in the universe and has free will...no machine will ever have these characteristics

    This point I don't know about. What you're saying is fundamentally religious, ascribing to people some element that makes us more than the mechanical and chemical interactions that comprise us. That may be the case, or it may not. Even for those who believe in God, it has proven tricky to assume supernatural explanations, because physics often finds natural explanations for them.

    Predictive power is necessary, but not sufficient.

    I don't agree that it's "the most fundamental criterion", because it's not a matter of weighing various criteria, some more important than others, and saying "yep, this theory is good enough, it's a keeper". Instead, all of the criteria must be met. An explanation must make verifiable predictions, those predictions must be borne out, the explanation must not be easily variable to accommodate any observations and must imply its own reach.

    As to your example, QM doesn't say that systems only behave quantum mechanically below a certain scale. They behave that way at all scales... it's just that at larger scales the collective probability of observing the quantum "weirdness" is so low that it effectively never happens. At least in most cases: Young's experiment shows that QM behavior can be quite apparent at larger scales.

    FWIW, I don't consider QM to be an ugly theory at all. In particular, I find the many-worlds interpretation of QM to be quite elegant and beautiful -- though still quite brain-twisting and very different from our common conception of the world. But then, frankly, classical atomic theory is also quite alien to our common conception of reality. For example, the notions that solid matter is nearly all empty space and that the fact that we can't walk through walls is actually due to counterposing fields not because the matter of my forehead and the wall really "collide". The notion that we live on a spherical body rotating around the sun is also quite counter-intuitive, frankly. It only seems clear and obvious because we're used to it. So degree of match with human perceptions of reality isn't really a useful yardstick.

    Interestingly, I think beauty and elegance are useful yardsticks, though, because they tend to bear precisely on the "hard to vary" characteristic of good explanatory theories. The more complex a theory the less elegant and beautiful it is, and the more "knobs" there are to tweak to explain different observations. Current explanations of subatomic particle physics are deeply unsatisfactory... and not only are they ugly, with their explosion of seemingly random types of particles, we don't have explanations that tell us why we observe all of those particles and not others or (with some exceptions) what all of the other particles may be. This lack of reach and excess of variability indicates that we don't really have a scientific explanation of subatomic particle physics, even though we can make some predictions.
