    That is excellent work and well demonstrated by the article.

    > If you saw creatures behaving like this in the wild, you might attribute some rudimentary intelligence to them.

    > But we’ve just shown you how this apparent intelligence arises from the bottom up, with just four neurons and two connections. There’s no magic here. In this view, behavior emerges from neural circuits.

    Isn't the conclusion here that very simple behaviors like the sparks are intelligent? I would say even a single neuron has some tiny amount of intelligence, and what the author means by "no magic" and "emergent behavior" is just a different perspective that minimizes it.

      Intelligence is an arbitrary term humans assign to stuff subjectively.

      Take out the "human" and it's all just algos on a scale of complexity.

        Agreed. Take human out and any system capable of doing an if-else is intelligent to a certain degree.

          If basically everything is intelligent (e.g., incl. rather simple chemistry), does that word mean much then/is it a useful term?

            Yes, words that label parts of continua are useful, even if they don't have well defined boundaries.

            Kind of amazing how simple that fact is and how many arguments are caused by people not realising that it's true.

            Here are some examples: town, artery, yellow, loud, tall, kind, woman, road...

            Honestly it's hard to think of words that do not exist on a continuum. The exceptions are mostly low level maths/physics things.

              Sorry, but if everything is intelligent then why is a word for it even needed like it is used today - stating that intelligence is an intrinsic property of matter, moves the discussion quite a bit, I think, as it changes what we denote there.

              Unlike "artery" which certainly isn't every blood vessel or "yellow" that isn't every color.

                "Intelligence" = vessel or color in your example

                There are words that distinguish between types/degrees of intelligence. Basal/proto intelligence applies to cells and bacteria. Somatic intelligence is a level higher at tissue. Superintelligence you've no doubt heard of.

                It's true that "intelligence" is general/umbrella and doesn't have much meaning, but more specific terms do exist.

                  So intelligence is an intrinsic property of matter then? It's not a mainstream view now, but who knows.
                  • kylecazar 8 minutes ago
                    I personally don't think it's an intrinsic property of all matter, but an emergent one with interaction specifically. Systems have intelligence, not particles, and to be a system, you must have constituent parts (which may not be intelligent themselves). That's why they say it 'emerges'.

                    A cell is a system, as is a virus, a tucan, a human and an LLM. They exhibit different levels and brands of intelligence, hence continuum.

                    That's the popular view among scientists/philosophers/my podcasters, at least, and it makes sense to me!

                Most human societies claim dominance over “everything else” aka “nature” and in order to do that you need a reason “humans” are different from “nature”
                • RandomLensman 36 minutes ago
                  Maybe, but making intelligence an intrinsic property of matter feels like a bold step.

    Check out Valentino Braitenberg's vehicles. It's one of my favourite books ever.

      A K Dewdney did a quick sketch of the early chapters of Braitenberg’s book in his Computer Recreations column in _Scientific American_ in the late 1980s.

      I came here to mention that book.

    Growing up I tinkered with BEAM robotics. It's a philosophy of design that begins with these types of very simple reactive circuits usually from scavenged parts. It's nice to see someone break down the effect of different variables in the design.

    A similar mechanism is how lactobacillus actually find food even though their motor propels them in random directions.

    They have sensors for the concentration of food and basically stop moving when it's good enough and start when it's low.

    Read this and instantly though about Elmer and Elsie, https://en.wikipedia.org/wiki/Elmer_and_Elsie_(robots)

    Best thing is, you can physically build this with a few discrete analog components! Search terms: light-bot, or light following robot. You can try to create swarms adding a light to the rear end of your robot
