A Worm's Mind In a Lego Body
mikejuk writes The nematode worm Caenorhabditis elegans (C. elegans) is tiny and only has 302 neurons. These have been completely mapped, and one of the founders of the OpenWorm project, Timothy Busbice, has taken the connectome and implemented an object oriented neuron program. The neurons communicate by sending UDP packets across the network. The software works with sensors and effectors provided by a simple LEGO robot. The sensors are sampled every 100ms. For example, the sonar sensor on the robot is wired as the worm's nose. If anything comes within 20cm of the 'nose' then UDP packets are sent to the sensory neurons in the network. The motor neurons are wired up to the left and right motors of the robot. It is claimed that the robot behaved in ways that are similar to observed C. elegans. Stimulation of the nose stopped forward motion. Touching the anterior and posterior touch sensors made the robot move forward and back accordingly. Stimulating the food sensor made the robot move forward. The key point is that there was no programming or learning involved to create the behaviors. The connectome of the worm was mapped and implemented as a software system and the behaviors emerge. Is the robot a C. elegans in a different body or is it something quite new? Is it alive? These are questions for philosophers, but it does suggest that the ghost in the machine is just the machine. The important question is does it scale?
Initially read it as "A Woman's Mind in a Lego Body". Wasn't quite sure where to go from there so I squinted a little bit. Fortunately Timothy saved me from having to explain to my wife just what 'that stupid Slashdot article" is about.
Faster! Faster! Faster would be better!
If you want to scale this worm's mind in a lego body, try MongoDB. It's web scale and has sharding. It just works.
it will become a new earther. Give it two and it will become a politician.
Superstition comes from the instinctive default assumption that unexplained things are animate things out to get you.
The false positives are a nuisance, but living on the savanna without modern science it was sometimes the safe assumption.
so it begins
The key point is that there was no programming or learning involved to create the behaviors.
Yes, there was. The behaviors didn't just "emerge", they're coded into the robot.
Try Duplo.
I read that as "A Woman's Mind in a Leggy Body."
I'm going to bed now.
The higher the technology, the sharper that two-edged sword.
Emulating the connectivity and functionality of neurons is pretty awesome, but it would seem the next logical step would be to map and interpret how memories are stored and processed, as well as organ feedback (skin, smell, glands). What's really interesting about this is that it shows, at least to some degree, that a simple brain can be reproduced using mathematical relationships (programming) and "run" with a I/O feedback loop. As far as the philosophical stuff, I think eventually we'll be forced to accept that life is a type of machine and that the "ghost" is an illusion emerging from its complexity. Other than better neuroscience, the main thing holding us back is pride.

Our own brains are proof that it scales, at least if you get the implementation right. Unless you're of the rather woolly Penrose school of thought, there's nothing "magic" involved in the physical implementation of the mind, it's just physics. The devil is in the software model that it runs. We have no idea how that is architected, but experiments like this will probably help to shed some light.
... the Lego brick
So the creator of Battlestar Galactica dies, and we learn that people are building LEGO cylon worms. Interesting...
This is the first step to the "cat chasing a mouse" AI in the Charles Stross's book Accelerando. They programmed the AI to see the missile's target as a mouse so it would chase it. We're just a few steps away from this.
Despite Elon Musk's recent anti-AI ranting (which does have truth too it), we'll get our flying cars once we can implement a "bird-based" AI to fly it for us. The more we replicate nature in our tech the further we'll get. I predict we'll see "emergent features" such as social hierarchies, empathy, emotions, and such in our tech the more neurons we add without even really needing to program it on purpose.
It's fascinating but it's not C. elegans. It doesn't reproduce. It doesn't die. It's not alive.
The sensors are implemented in large, electro-mechanical hardware. Not biochemical systems. It has no telomeres. No cells.
Humans have several subsystems: digestive, endocrine, pulmonary (pneumatic and hydraulic), muscular, skeletal, nervous. If they manage to create an electro-mechanical system to mimic the nervous subsystem, it's just that - mimicking the subsystem. It would be an amazing feat, and what's been done here is fascinating, but we're still quite some distance away from stating that a human - or C. elegans - is 2^n nand gates.
Is something that mimics a nervous subsystem via an electro-mechanical system equivalent to the nervous system? Be it the 302 neurons of the C. elegans or the approximately 100 billion of the H. sapiens? It might become very intelligent... more intelligent than us... and then we'd have a problem... Frankenstein didn't appreciate being locked in his form...
Would it really feel emotions? Pain, rage, joy, fear, ennui? Or is it just mimicking them?
Fascinating stuff.
it's about moral ones. If we make a perfectly simulated animal brain and it works just like the real thing does that mean we've made an animal? Do we consider that animal to be alive? Does it have less "worth" than a flesh and blood creature? Better that we answer these questions now than when we have robots asking us if they have a soul.
A bullet may have your name on it but splash damage is addressed "To whom it may concern."
Does it Blend.
(btw, fk systemd, fk beta)
I first learned about C. elegans while researching simple neural systems. There's a nice map of the neural connections available. Today, I stumbled across the name again, when Wikipedia informed me that Caenorhabditis elegans is the most primitive animal that sleeps. Now I find that there's a robot worm that I'd consider to be alive.
This guy's pretty awesome.
You do not have a moral or legal right to do absolutely anything you want.
This is some sort of parasite like "ringworm", not an actual worm, aka earthworm.
Buck Feta. You know what to do.
Life that has never seen the surface of the Earth.
sex and proliferation ???
Upps, we forgot about _that_....
More importantly. Is it WEB-scale?
Mrs Hoover, I ate my Lego worm.
The answer may be found here.
Imagine a beowulf cluster of those.

Error:
Scientists have mastered emulating a worm's brain. But what of that of a human?
To draw a parallel, they have successfully mastered Tic-Tac-Toe. Now, are you capable of mastering Thermonuclear War?
Or is the only winning move not to play?
The important question is does it scale?
No. The important question is does it run Linux? It's a given that it runs NetBSD - sure, my toaster does.
It must have been something you assimilated. . . .
if this is really is what it's claimed to be, it has huge implications.
I can't help thinking, what when the robot gets hungry or horny? I'd rather not have a creature suffering because of my stupid pride.
Get stupid answers, No, No,Yes.
And when robots ask if they have souls we say "No and neither do we, It's all pointless emptiness and someday it will all be over any your choices will have no meaning." If an AI can get through the inherent futility of existence without shutting down we slap a QA sticker on it and sent it off to work, if you don't think that's fair just consider it expedited teen angst.
Does it use Systemd or SysVinit?
They did not emulate the functionality of a neuron. If you read up on the subject you will find that the neuron is a network all by itself with spikes moving forward and backward, local spikes on the dendrites, the dendritic tree performing multiple simultaneous linear and non-linear computations, etc. etc. etc. They used an extremely simplistic formula that completely skips over these computations that have been shown to be very important for the proper functioning of the neuron.
You don't normally use it for that...
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
There are also politicians who have done well for 20 years using only 302 neurons.
Superstition seems to come from a human insistence that things are better when they're a mystery than when they're solved and understood.

Fun book that demonstrates how a handful of sensors mapped to single functions can express some very complex behaviors and appear to be quite alive.
If you look at the amount of things in this world that can make you dead, if you didn't understand them, it's a good reaction.
Car coming towards you. Will it kill you if it doesn't stop? Yes.
Bus. Plane, motorbike. Injury or death if it doesn't stop.
Any object falling towards you, pole, power line, rock, house (flood) etc. Will it kill you? Good chance of it.
The human race wouldn't have survived if it wasn't for that instinct, it's a good and proper instinct to have. It SHOULD require higher level thinking to investigate somethings potential danger before deciding we shouldn't vaporize it first. On instinct, we don't know enough that we should risk our lives until we are confident it is killing us.
just what we need, creating mechanical exoskeletons for creepy-crawlies.
enough for a Dune reboot?

Does it have less "worth" than a flesh and blood creature? Better that we answer these questions now than when we have robots asking us if they have a soul.
No (you also have to simulate the body perfectly otherwise you're created something new that is not precisely the original animal).
Yes (if you answer "no" it'll only cause a shitstorm when the technology gets more advanced and we have to decide what to do with people in robot bodies).
No (again, this will become obvious once you consider a person uploaded into a robot).
Pretty much all the moral questions become pretty obvious once you sit down and think about them from the perspective of "what answer is the generation after the one that makes this work going to think is bigoited and narrow minded?"
No need for a Lego body when you can download Bugbrain, the single best teaching software (AI or otherwise) I have ever encountered. It's worth digging up a 32 bit machine to run it if you have the time. I tried contacting the creator once, it really should be converted to Flash so everyone can play it, but I got no response.
I completed the game (I'm no expert, but the software is so good it also means I know a little), and I came away unconvinced that neurons are completely understood yet. I think there's more at work than just sigmoidal backpropagation.
User Datagram Protocol (UDP) packets between neurons? What the hell are they doing? Neural network != computer network. It's clear they have no clue...
You don't normally use it for that...
What do you think neural implants are made of? ;)
"The neurons are addressed by IP and port number."
IPv6 I hope!
Your line of reasoning does not support the conclusion that the machine does not feel.
Also, you conflate the concept of feeling with the concept of self. The concept of self is actually very nebulous, and plenty of people report experiences of conscious apart from a concept of self (through meditation practice and/or drugs). So, to simplify:
If qualia do not exist, then the discussion is moot.
If qualia do exist, then the question of what does and does not attain them is very interesting, and the possibility that a machine can do this is made even more likely by modeling experiments such as the ones done in this article.
