What I'm guessing at is that "motivation" is probably a useful fiction that's part of our conscious experience because it makes it easier for our brains to keep track of all the things we're doing, not to mention all the things everyone else is doing.aoeu wrote:What you are saying is more like "reported motivation is different than actual motivation".
Christine Korsgaard wrote:Reason” and related terms like “rational” can be used in either a normative or a descriptive way. When we use these terms normatively, “reason” is synonymous with “good reason.” When we use the term descriptively, a reason is some consideration on the basis of which we decide to do something. In that sense, there things you do for good reasons, things you do for bad reasons, and things you do, but not for reasons at all – like, say, scream when you see a monster at the window. (It’s not like you think, “oh, a monster. I guess I had better scream now.”) It’s because we use the terms both ways that we can say, “that’s a bad reason” (descriptive use) and “that’s no reason at all” (normative use) and mean essentially the same thing.

Most of our understanding of the world will happen subconsciously, and most of that will be based on habit, bias and shortcuts. When I look at most theories of consciousness or intelligence (or what we could call conscious intelligence, intelligence we're aware of), there's very little acknowledgement of this.

I think you'd need to generate some sort of general-purpose AI before the concept of a machine desiring something even means anything. Most AI research right now is about developing AI for specific applications.EMTP wrote:It certainly isn't. Rational thought is an outgrowth of goal-directed behavior.

I don't know a lot about AI projects, but I know that part of any rigorous analysis involves 'culling' the irrelevant data. And 'culling' is a type of analysis--ideally, a cheap and fast analysis, but an analysis nevertheless. Humans do this (we make some quick, dirty, often unconscious decisions about what is and isn't relevant) and programs do this (they apply some quick, dirty algorithms to reduce the amount of data they have to use more expensive algorithms on). Effective culling techniques means analyzing enormous quantities of data very quickly and very cheaply.TrlstanC wrote:I know that's a form of processing, but it's certainly not making use of, especially if the throwing out happens way before we get a chance to "think" about it, at least consciously. This is in contrast to most AI projects, that specifically aim at capturing lots of information and analyzing it all.
We don't store everything in our brains. We employ clever compression techniques (like storing data we're likely to forget in a book, for example, or mnemonic devices). Computers also have their own clever compression techniques (like reducing five hundred zeros to a single zero associated with the number '500').TrlstanC wrote:And it's a good thing that we do throw out most of it because while 2.5 petabytes of information (which is wildly speculative since we don't really understand how information is stored in the brain, and that's basically just counting the number of connections between neurons to get to that number) it would only be enough for about 1/2 lifetime's worth of HD video. So, no intelligent thoughts, feelings, or any other connections or sensory data. A small fraction of the data generated by one of our senses, with no processing or intelligence behind would completely fill up a brain in about 30 years.
Not to say that's not an impressive amount of storage (if that's actually an accurate number), but clearly the actual amount of data we deal with in a life time in many magnitudes greater.
Culling isn't merely a function of the conscious brain. The design of our eyes--allowing us to perceive a limited range in front of us (but not in back of us) is a sophisticated (albeit flawed!) data-culling method produced through the process of evolution. That design can be described as a means through which we process relevant data and 'cull' irrelevant data.morriswalters wrote:We don't throw out data so much as we never acquire it, or we acquire it and use it and then forget it. And a lot of data never enters our conscious experience at all. Try driving your route to work in your mind. How much of what you remember is actually there? When I play with this I find that a lot of what I visualize is fabricated. For instance I find that I almost always viz it with trees in the summer. The things that I remember best are the things that I focus on the most. The thing is that most of what you see or experience is not needed other than at the moment it happens. I expect that someone is right in that it's probably true that for AI they may need to figure out why any life struggles to live in the first place. That's an opinion.
I'd be interested in seeing a definition of "goal-directed behavior" from you that didn't presuppose this claim, followed by a demonstration of this claim, because it is not at all self-evident to me.EMTP wrote:Goal-directed behavior is a product of desire.

However, if you look at modern machine learning techniques, it is based around a rudimentary punishment/reward system and learning behavior based around that. It's absolutely goal-directed and, in the absence of general purpose AI, seems like the closest you can get to "desire."

It's fascinating to me how much technology fails to simulate biology--finding alternative solutions to problems like movement that are far more practical and far more effective than the solutions evolution has given us. There are a few exceptions, but things like airplanes only started working once we stopped trying to rebuild the flapping motion of a bird's wings.EMTP wrote:I think AI will develop like mechanized transportation. Do we have a machine that can walk, jump, climb, and run like a human can? Not yet. Maybe in the next hundred years. But meanwhile we have bicycles, cars, trucks, planes and spacecraft that can do all sorts of things we can't. Practical AI research will give us cars and planes.

EMTP wrote:If you program a "goal" into an AI, whose intent does it express? Yours or theirs?
If you leave it alone in a relatively sterile, stable space without food or water, it won't 'die' after several weeks. Also, if you take it apart, you can put it back together again and it still works.EMTP wrote:More practical and effective when you're building a machine. Not better objectively. Our engineering is still crude and sloppy compared to 4 billion years of evolution. Yep, that jet's pretty fast. Call me when it is self-repairing, self-replicating and runs on unpreprocessed organic garbage that it collects itself.

Can you name one? The fact that life eventually fails may just be an indicator that there are limits to the process, just as there are limits to machines.The Great Hippo wrote:We're already modifying ourselves with machines--replacing organs with devices that accomplish similar tasks, only with extraordinarily greater efficiency.
Dunno about the energy thing. How much energy is required to maintain a hard-drive? What about a flash-drive? Either way, I don't see the relevance; I'm just opposed to describing machines as sloppy compared to biology--because machines strike me as a much more precise expression of design. We're badly coded--because the programmers who wrote us shotgunned their way through it over millions of years until they cobbled together something that works 'just enough' to get the job done.morriswalters wrote:And it will do absolutely nothing it wasn't designed to do. Machines derive their motivation from us. They break under use, fail in unpredictable ways, and require way more energy to function.
I edited out the 'extraordinarily greater efficiency' after I realized it was hyperbole (and to be honest, I don't know enough about the intersection between machines and biology to be making assertions like that). That being said: When biology fails, we use machines. For example: Dialysis.morriswalters wrote:Can you name one?

Your analogy implies that we can see where we are going and what we are doing. But put that aside for the moment. Say for a moment that we are able to do precisely that, design a new intelligence. Why should we. What is our response to our evolutionary ancestors who evolved differently? We either hunt them or put them in Zoo's. I don't find that prospect to be particularly appealing. We would be the inferior branch, if you believe that AI would be more intelligent than us. The presumption that is always implied is that however it might come into being, that it's goals would be ours, no matter it's process. I have no reason to believe that this is true.The Great Hippo wrote:Yes, and biology isn't simple, because biology is a machine designed by a progressive, slow process that responds to pressure. Biology is a blind watchmaker; but we aren't blind--and can therefore design better, simpler, more functional watches.
The premise I'm putting forward here is that it is reasonable to expect that we will build a better intelligence than our own, and it is unreasonable to assume this intelligence will, by necessity, think like us.

This could easily be taken to be saying that all of our decisions are perfect, given all available (and historically available) information. Or that, there's no way we could've been more evolutionary successful by making better decisions.morriswalters wrote:And perhaps I am mistaken, but we process as much information as we need. Think parsimony.
Evolution doesn't make decisions. It's trial and error or something akin to that. And the amount of information one person could take advantage of is limited by the time he or she has to do it. Information is not as important, from my point of view, as the ability to do something with it. Think of it this way. Put a person on an island and give him a computer with everything we know to date, and the tools to do all the science and craft we do today. How is he limited? Even if he had the capacity to learn everything and know everything , it still wouldn't mean anything because, in and of himself, he is limited by his ability to do. There aren't enough days for one man to utilize all the information that he has. The question, could we as a species, make better decisions given more information, seems to have the idea in the background that we could have perfect information. Do you believe that we could ever have that?TrlstanC wrote:This could easily be taken to be saying that all of our decisions are perfect, given all available (and historically available) information.

I'd agree that we probably utilize more information from our environment than most (possibly all other) species, and that we certainly utilize enough for it to be a significant advantage. But I don't think I'd say we utilize (or process) as much information as we need - without adding what we need it for.
Yeah, I'm pretty sure that no discussion or theory put forth by anyone who actually knows something about how the brain works would suggest that we have essentially limitless brain power.TheGrammarBolshevik wrote:Examples?TrlstanC wrote:A lot of the theories or discussions I read about consciousness seem to include the assumption that our brain power is essentially limitless, or is at least more then up to the task of 'intelligently' handling all the data that's thrown at it.
No, we process as much information as our ancestors needed to have a reasonable chance at reproducing. The environment they lived in was, for the vast majority of human existence, *far* less information-rich than the one we live in now, even just in terms of the number of people we're expected to "know" or the number of tasks we're expected to be able to do simultaneously or in short succession.morriswalters wrote:And perhaps I am mistaken, but we process as much information as we need.
No, it definitely doesn't have that idea in the background. What in the world gives you the idea that it does? The claim that we'd do better with more information just means that we'd do better with more information, and nothing else. Why are you making the jump to having *all* the information?morriswalters wrote:The question, could we as a species, make better decisions given more information, seems to have the idea in the background that we could have perfect information.

Citation needed. Anthropologists studying modern hunter-gatherers have found they maintain detailed knowledge of hundreds to thousands of species of plants and animals, not to mention local geography, a variety of crafts, and complex social relationships.
Jared Diamond argues that the hunter-gatherer lifestyle is more intellectually stimulating and challenging than the typical "glowing rectangle" lifestyle in the first world. I'm inclined to agree.
