In lectures I thermostats as an example of an intelligent system that matches most attempts at defining intelligence. And I have no qualms saying they are intel

  A bimetallic strip is intelligent? https://en.wikipedia.org/wiki/Bimetallic_strip https://en.wikipedia.org/wiki/Bimetallic_strip Thermal expansion is clearly a physical reaction; if arranged in an intelligent way, it's able to achieve some human-relevant objective... but if we're going to say that two pieces of bulk metal hooked together is intelligent, then the term "intelligence" is so broad as to be roughly meaningless.

    A bimetallic strip is only intelligent when placed in the context of a thermostat system. Similarly, your brain isn't intelligent when removed from your body and placed on a table. Brains are only intelligent when they're in conjunction with living bodies.
    • aydyn 3y ago
      A brain is intelligent regardless of where it is, so long as it's "powered" so to speak.
      • lupusreal 3y ago
        Sure, replace a living body with a machine, and replace the thermostat around the bimetallic strip with some other kind of mechanism. It makes no difference.
        • aydyn 3y ago
          So a brain is only "intelligent" in certain (but infinite) contexts as opposed to intelligence as an inherent property of a brain? If so, your definition of "intelligence" is incomplete. What are those contexts? Can you really generalize all of those contexts for all possible intelligence systems? That sounds like an epistemological nightmare.
          • lupusreal 3y ago
            Intelligence is not an inherent property of a brain, brains are only intelligent when placed in particular configurations with supporting hardware. Are you going to fart at me too?
      • westmeal 3y ago
        I used to think this but I don't know anymore. Without our bodies to provide stimuli what input is the brain going to use for thinking or reasoning? So much of what we do day to day is hard-linked to our body/sensorium. The brain without the spinal cord/nervous system is useless.

            Not without lungs, you don't... But actually there's a real interesting thing here. People used to believe that the heart did the thinking. Phinneas Gage upended that theory, and now people think that the brain is the thinker. More recently, we're learning that the gut has a massive neural network, and the brain-gut connection is being investigated today. Likewise, "muscle memory" isn't in the muscles nor the brain, it's distributed among neural clusters all throughout your body. How much of "you" (your knowledge, your personality, your physical skills) is actually contained within the head is entirely non-obvious.
            • aydyn 3y ago
              This is sophomoric. First of all, muscle memory is not contained in your muscles or "distributed" throughout your body but is known to reside in your cerebellum and basal ganglia. The nerves going down to your muscles are simply a conduit for actuation, a wire, nothing more. As far as your gut, if you claim that a thermostat is intelligent then sure your gut is also intelligent (don't forget the microbiome in there too).
              • jampekka 3y ago
                Peripheral nervous system has significant plasticity and its reflex archs can produce complex and purposeful behavior without the brain. E.g. cats can walk with their brain removed and famously decapitated chicken do all sorts of stuff. Octopi don't even have a centralized brain.

    Our brains are clearly physical reactions. Check and mate.
    • bumby 3y ago
      Perhaps check, but I don't think it's checkmate until you can explain the hard problem of consciousness via physical reactions.
      • jampekka 3y ago
        What makes you assume thermostats aren't conscious?
        • daveguy 3y ago
          Because they don't have any other higher level function that could reason about the state other than a single binary response. If intelligence is a continuum you might say it is at the lowest end (a bit state and actuation on that state). But consciousness seems more like a meta-intelligence that would require more than one bit and one actuation.
        • bumby 3y ago
          I don’t make any of those assumptions. My point was that I also don’t know that we can distill consciousness to strict materialism until we can find the mechanisms to explain the hard problem of consciousness.
        • therobots927 3y ago
          this really is getting at something important. however the question I would pose is, if the thermostat is conscious, does it have a sense of self, i.e. an identifiable boundary between itself and the world around it? I would say not. My understanding is that humans have an identifiable region(s) of the brain that correspond to a sense of self: https://en.wikipedia.org/wiki/Neural_basis_of_self#:~:text=Two%20areas%20of%20the%20brain,the%20ability%20to%20self%2Dreflect https://en.wikipedia.org/wiki/Neural_basis_of_self#:~:text=T.... I think in a lot of these conversations people say consciousness and assume that consciousness always mirrors their own, which just so happens to come along with a sense of self for 99.9% of sober individuals. So I think it's important to distinguish between the two things.
  • bumby 3y ago
    Some definitions of intelligence (or even consciousness) are systems that simply process data. From that context, a thermostat is processing temperature data. It also underscores the GP's point that there isn't necessarily a consensus on the definition.
    • s1artibartfast 3y ago
      You can set a context as broad as you want, but it changes utility. You can set a definition and context so broad that everything and anything is intelligent. The possibility of an outlandish alternative, does not does inform on if a consensus exists or not
      • bumby 3y ago
        You can set the context as narrow as you want (e.g., abstract reasoning specifically defines intelligence). That might make your ontology feel crisp, but it also doesn't make it correct; it's still arbitrary and a matter of convention.
        • TeMPOraL 3y ago
          Indeed, the only value of categories in how useful they are. It's clear there's a continuous spectrum of intelligence/complexity. I believe the main reason we're still arguing in circles about what is or isn't intelligent, is that we also have a distinct, ill-defined category called "intelligence" that carries ethical / moral connotations. We don't know how to handle a continuum of moral weight / personhood. It's useful in many ways to put a thermostat, an LLM, a monkey and a human on the same "intelligence"/"complexity" scale - there are many interesting things to discuss other than moral weight. And then, for discussing personhood, it makes no sense to include a thermostat.
        • s1artibartfast 3y ago
          sure. but there is value in defining a useful working convention so that people can discuss, learn, and study. Interjecting the perspective that words are meaningless constructs is rarely helpful. If someone wants directions, telling them that there is no concrete metaphysical concepts of north, south, left, or right, isnt constructive.
  • tim333 3y ago
    I think intelligence is a continuum from not very intelligent to very intelligent. I guess a bimetallic strip would be at the bottom end of the scale above a lump of coal but below Einstein. At least in thermostat form it can keep something stable in contrast to say Turkey and it's currency as mentioned in another HN thread today. Maybe they could rig a bimetallic strip to raise or lower interest rates with a heat input driven somehow by consumer prices? They could then use that to replace Erdogan.

  • NoZebra120vClip 3y ago
    There are some who claim that a bimetallic strip shows evidence of intelligent design, but every fifth-grader knows that if a million volcanoes erupt over 5 billion years, there is a lot of weird stuff that can result from that random activity.
• mannykannot 3y ago
  Language is quite flexible, but I don't think it is very helpful to call a thermostat intelligent. Doing so does not advance our understanding the sort of self-aware, theory-of-mind-holding intelligence that is generally meant by the term (putting aside its alternative meaning as a synonym for information), and adopting the broad definition just increases the burden of disambiguating what we mean when what we mean is the latter. The broad definition is not justified by the fact that certain attempts to define the term would attribute intelligence to thermostats; a more useful conclusion to draw is that the definitions in question could be improved. It is sometimes said that we won't be able to gain an understanding of intelligence until we have a precise definition, but it's actually the other way round: definitions get tighter as our understanding increases. We now understand many things that not only were lacking definitions in the past, but were not even imagined.
  • jampekka 3y ago
    Thermostat with a servomechanism is self-aware of its state. A thermostat could be quite simply augmented to have a theory of another thermostat. Probably there are such coupled termostats. I use intelligence mostly just as perspective of analysis to a system. E.g. Can it be seen to process information? How complicated is the transform from the information to some action? Does the processing lead to some good outcome, e.g. self-preservation of the system? Could the information processing be improved for this outcome?
    • mannykannot 3y ago
      Saying that a thermostat with a servomechanism is self-aware is just repeating the same broadening-beyond-usefulness with a different (though related) concept, in this case self-awareness. The difference between the self-awareness of humans and that which you see in a thermostat is vast, and understanding how a thermostat works gives no useful insight into how the human mind works. Any system processes information, and in a thermostat it is not complicated at all. Even the most self-aware thermostats currently being manufactured are not going to improve themselves on their own volition. Applying the term 'intelligence' this broadly turns it into an empty tautology, or a little piece of uninformative noise on a communications channel, no more useful in understanding those systems than in understanding actual intelligence.

  > I have no qualms saying [thermostats] are intelligent > Intelligence is a very vague and very context dependent thing That's either contradictory, to state that something has property X where X is vague to the point of undefined, or you are setting a very low bar for intelligence (I'm actually okay with the latter). Just a question, if a bimetallic strip can be intelligent, is a marble intelligent for having the wit to find a low point on an uneven surface by rolling downwards?
  • jampekka 3y ago
    The marble question is good. For most purposes I'd say the bimetallic strip (one connected to an actuator at least) is more intelligent than a marble. Studying dynamics of internal properties of the termostat is more fruitful than of the marble that is easy to describe as an unchanging object. Taken to the logical conclusion, we are all just rolling downwards to a minimum energy state just like the marble. I don't think intelligence is an intrinsic, let alone binary, property of an object or a system.
