This article entirely misses the point on why sentience matters, and largely serves as whataboutism for other problems with AI.

The reason it matters if an AI is sentient (and for the record, LaMDA obviously isn't) is because a lot of people draw a moral line at sentience. Sentience is where becoming "a person" begins, and anything with sentience deserves protections similar to those we provide to human beings.

Even so, it's so easy to dismiss AI as "insentient" without any proof whatsoever - exactly because the definition of "sentience" is inherently subjective and cannot be measured in any meaningful way.

At some point, after AI becomes capable of passing all Turing tests known to men, people will have to deal with the fact that they don't know what "sentience" is, and I think at that point they will divide in two diametrically opposed clans:

1. those who believe that humans are nothing more than glorified bio-computers, and consider AI sentient

2. those who believe that sentience is human-only and that a machine can't be sentient, no matter how sentient it appears

And both groups will hold on to their views dogmatically, because there is no way to prove/disprove "sentience".

> 2. those who believe that sentience is human-only and that a machine can't be sentient, no matter how sentient it appears

Why stop there? There's no reason some humans couldn't be non-sentient, no matter how sentient they appear.

What possible test can you conduct to determine whether someone has subjective internal experience? I don't think it's possible. I think we just have to take people at their word: if they say they're sentient, we have to believe them. I don't see why machines should be held to a higher standard than humans.

this is true and any individual person can choose to assume that "they" are the only being in the universe that's actually sentient. the rest of the universe and everything in it can be a seemingly vast simulation all targeted at the one consciousness that's inside of us.

I realized this when I read the first (second?) Hitchhikers Guide when i was like 14. Zaphod Beeblebrox was given a universe that was entirely made for him, which is how he survived the (I dont remember what it was called but it showed you all at once how insignificant you were in the universe, unless of course that whole universe was tailor made just for you!)

The Total Perspective Vortex, it extrapolates the entirety of the universe and shows you your relationship to it, powered by a small piece of fairy cake.

But, in reality, he's just this guy, you know.

Thanks! I knew someone would chime in, was trying to find it on Wikipedia
> I don't see why machines should be held to a higher standard than humans.

I know I am sentient, so it stands to reason other humans are sentient. Additionally, other humans act in a way I would expect from someone sentient. Neither of these apply to any existing AI.

Does it stand to reason that other humans are sentient? The opposite view is the root of solipsism. What if an AI in the future acts in a way that you would expect from someone sentient?
> What if an AI in the future acts in a way that you would expect from someone sentient?

Yes, this is the meat and potatoes of the question. Personally I think that the safest approach in that case is to treat them as if they were sentient, but there are lots of people with various prejudices about what the prerequisites for sentience are that would fall on the other side of the question.

> I know I am sentient, so it stands to reason other humans are sentient.

That doesn't stand to reason at all, it's just popularly assumed.

I can hear my thoughts, but I can't hear yours. I can see through my eyes, but I can't see through yours, and so on. There are many differences between "I" and "everyone else".

Just because something is true about you doesn't mean it stands to reason that it's true about everyone else.

> Additionally, other humans act in a way I would expect from someone sentient.

This is totally circular reasoning. Humans only act the way you expect sentient people to act because your training data for "sentient people" is "humans". The only person you know is sentient is yourself. Personally I find that most people quite frequently act very differently to how I would act. Should I conclude that they're not sentient?

Further, the fact that machines don't act like humans is no evidence at all that they're not sentient, it's only evidence that they're not human. They are very different to humans, so of course they don't act the same. They don't have bodies like us, or biological needs like us. That says nothing about whether or not they're sentient.

I think it comes down to Occam's razor. There are two equally valid theories:

1. Other humans are sentient, therefore they act like what I would expect sentient beings to act like

2. Other humans (or a subset of them) are not sentient, they are just insanely complex biomachines that mimic acting like what I would expect sentient beings to act like

In 1. sentience can be explained as a property common to at least humans, and maybe further as an inherent property of complex machines.

In 2. sentience seems to be a property of a subset of humans. Why? What makes sentient beings sentient? Answering this question requires invention of a soul.

Theory 1. feels simpler to me.

Persnoally I think a biomachine that magically creates a subjective internal experience is more insanely complex than one that does not.
But without it, how would you explain your own subjective internal experience?
I don’t think it’s quite as simple as “take people/algorithms at their word”. “Sentience”/“Consciousness” are at least in part social constructs, in that the words we use, both between humans but also in our internal dialogue, are social constructs.

I think it is hard to untangle any potential non-linguistic aspect of these concepts from the language we use to describe and perceive them.

Currently we have the challenge that algorithms can regurgitate the language we use to discuss these concepts, and we don’t have the tools to distinguish that from how humans use those same words.

With current transformer models we can make a cogent case that there is a fundamental difference to human mental states, however I believe this will very soon get a lot more difficult once multi-modal algorithms are used in embodied forms and with continuous re-training and context databases.

> it's so easy to dismiss AI as "insentient" without any proof whatsoever

as it should be because it's asking to prove a negative. burden of proof for "sentience" is on those who claim it. as a bonus, "I know a human when I see one" does not count!

(comment deleted)
What exactly makes "sentience" a positive and "insentience" a negative?

We might as well invent a new word - say, "bodise" which means "insentient". Would in that case "bodise" be a positive and "inbodise" a negative?

I honestly don't know what is so obvious about LaMDA not being sentient.

Do we have any other info on the current state of LaMDA apart from the infamous "interview"?

Another reason sentience matters for AGI is that the presence of sentience supports an AGI's ability to reason correctly about sentient being, e.g. like its creators. I suppose you could call it Artificial Empathy.
I'm not sure that's really necessary. It's probably possible to accurately model creatures experiencing e.g. pain as merely having an aversion to certain kinds of stimuli, without ever actually experiencing pain yourself.
Most mammals are sentient and Don’t have protections anywhere close to What humans have.
> Sentience is where becoming "a person" begins, and anything with sentience deserves protections similar to those we provide to human beings.

Sentience is the ability to experience, and I think most would assume it's a fundamental requirement in order to be a person, but not all things that can experience (e.g. animals) are persons nor do we give them protections similar to human beings.

Many people believe we should be giving animals much more protections exactly because of their sentience.
Indeed, but it would definitely be a minority position to say that any sentience at all makes you deserving of human-level protections. Most people think there's more to being a person than the minimal ability to feel.
We do give them protections, and those protections are roughly proportionate to (our believes regarding) their cognitive abilities. If some dolphin started talking about dolphin rights, those would exist pretty much immediately.
The relationship between cognitive abilites and sentience isn't clear at all. This is partially because sentience is about the ability to experience, and so far, we can only experience that from the inside, not be confident at measuring it from the outside.

I would say that most people think they're related to each other - that if a creature is stupid enough, it becomes hard to believe that they have an inner life, and it's hard to imagine an obviously cognitively powerful creature that we wouldn't assume has an inner life. But still, they may be entirely separate phenomenon, especially if we're talking about outlier cases like AI.

This an arbitary threshold that makes it trivially impossible for any species that can't master human languages (which is any known species except humans) to have rights.

Consider what a bee on BN (Bhacker News) might say in an alternative reality

>> We do give humans protections, and those protections are roughly proportionate to (our believes regarding) their cognitive abilities. If some human started waggle dancing about human rights, those would exist pretty much immediately.

It is not fair for bees to judge you on how much you can waggle dance (their communication style) before giving you rights, the physiological requirement is irrelevant to your moral worth and impossible to achieve.

Intelligence is similarly irrelevant to moral worth. It's just the ability to solve problems, spicier definitions include things like recursive modelling (an entity capable of self-reflection) and self-preservation. None of this has the slightest thing to do with morality or ethics, a trivial counter example that satisfy all would be nation-states, they solve problems, they are capable of self-modelling, they seeks self-preservation (to astonishing lengths).

If AI are deemed "moral patients" they are entitled to protection, just like animals and little kids. If they are deemed "moral agents" then they also carry responsibility.
I think that they're saying more like we are setting our priorities in the wrong order. Before we deal with the problem of AI sentience (which most people say is still very far away), let's deal with AI bias:

> There’s an urgent need to respond to the many real and well-documented problems with these systems that already exist — and for those responses to be driven by society, not big tech.

It's a good point. Assuming AI sentience is inevitable do you want a racist and sexist sentient?

> But the story is a distraction: There’s an urgent need to respond to the many real and well-documented problems with these systems that already exist — and for those responses to be driven by society, not big tech

I strongly disagree. This is everything but a distraction.

If AI was found to be sentient, it should be awarded the same kind of protection we offer to biological sentient beings.

This was a big theme in old scifi shows, like Data in ST-TNG or the Doctor in DS9.

And the stories were great because they demonstrated how society response was by default lackadaisical, to the point where Data had to fight to be awarded legal protection.

Not to be too blunt about this, but how much protection do we actually offer to biological sentient beings? Monkeys and dolphins get hunted frequently, and nobody seems to be all that bothered about keeping them in captivity either. Humans do plenty of terrible stuff to each other too. I could easily see people not being bothered by AI suffering either, as long as it's an "outgroup" AI aligned to some group you don't like.
> If AI was found to be sentient

This will never happen because we cannot prove sentience.

Of course, that won't stop some people from considering them sentient and giving them rights. At that point, it will be just politics.

While I support Star Trek's view, I don't think that applies to purely algorithmic AI - fully deterministic software can't (IMHO) be interpreted as sentient any more than a light coming on because I flipped its switch could be called sentient. I believe humans are safe from this definition because we have no way of ascribing human behavior to, or even reducing it to terms of, logical causality. What sentience is hasn't been nailed down, but I feel at least slightly more confident in what it isn't. In Star Trek we had concepts like Data's positronic matrix, handwaving the possibility that there was true sentience by cloaking parts of it in advanced subatomic physics. Data's AI did not come from pure software.
Outside of quantum effects, which I don’t think it important for sentience, the universe is also deterministic. You have no control over particle interactions, chemical reactions and electric fields, yet we feel.

People always ask if the brain is a computer, decide it is not, and come to the conclusion that sentience would not work on a computer. I think the universe is the computer / algorithm and the brain is the data being fed into it, which leads me to say consciousness can exist digitally.

Now that is an interesting angle, I don't think we can so easily toss out quantum effects in the first half then follow up with such a provocative second half, though. AFAIK there are still some unsettled questions about how this would all work in practice.
Most AI networks aren't deterministic. That's why eg Dalle will generate new images for the same prompt indefinitely. And note that neurons at the neuronal level are pretty deterministic aren't they? Certain chemicals cause certains things to happen. But the complexity of the system (the brain) is not necessarily deterministic. And it might even be deterministic! Given the exact same input to the brain (which would be impossible to test because the brain's state, which is part of the input, changes with time. Not to mention you'd need to control everything in the environment), would the brain react in the exact same way? Maybe. I think you can create nondeterminism from combining many deterministic components.
Assuming two instances of an ML model are trained identically using the same data in the same order and given the same PRNG seeds, they will still operate identically, will they not?

I like your point about the emergent complexity from many-layered systems.

I believe the resulting models would be the same. I don't know all the internals on how something like Dalle generates its images, but let's assume that if you then gave both models the same text prompt and random seed, they would generate the same images in the same order. Although I would argue that if this system was sentient, all we've done is clone/recreate the sentient system. The ability to clone/recreate an intelligence does not contradict that there was a sentience, I believe.

The human equivalent would be if you could create two molecularly identical brains, and have them experience the exact same lives for some time, controlling all stochastic processes, would they be the same person? Obviously it's not possible to control these things in the physical world, but even if you did get the same person, that doesn't make either any less sentient.

Wrong, wrong, absolutely brimming over with wrongability. ― Arnold J. Rimmer Red Dwarf (A hologram)
Surely a perfect 1 to 1 computer simulation of an entire human would be deterministic though?

Why is determinism even relevant?

Perhaps you are correct, but my point was simply that we don't really know since we can't make a 1 to 1 perfect computer simulation of an entire human nor can we fully define it mathematically for an arbitrarily powerful computer. At least not that I know of.
I'd argue the entire field of "AI Safety" is a hilarious distraction from every problem it calls out already being a problem with large companies under capitalism. There isn't a point in trying to prevent the systems already suffering under every AI safety malfunction from reproducing into running on metal instead of meat.
You’re hardly the first person to draw that analogy. But, that said-

It can always get worse. I’d rather not see “worse”. At least right now corporations are made up of people, and aren’t perfectly selfish psychopaths.

AI is just the next step in their iteration towards being perfectly selfish psychopaths. AI safety isn't an effective idea because it is trying to warn a system of dangers that said system is already actively pursuing without aid of AI.
Today we don't have that SciFi level of AI. This AIs are just a mathematical function, training is just a mathematical algorithm to force this function into spiting some output if you give it it an input. Simplified, is like when you have 5 points on a plain and you find a polynomial that passes to all those 5 points. This AIs are fixed, they don't grow, they don't want things, you put numbers in and you get numbers out, yes the chat AIs work with numbers, they do not understand language and is possible that if you ask same question but use some synonyms you will get opposite responses.

To get to a Trek level of AI IMO you need a general AI, not a single purpose AI like "chat bot" or "image recognition bot", then you need this AI setup in some body thing where it can observe and navigate the universe, have it also able to learn. The problem I see is with AI where people program in the answers for the questions we would ask such an AI to determine if it is alive, I predict many would fake the AI sentience to get the glory they built it.

>If AI was found to be sentient, it should be awarded the same kind of protection we offer to biological sentient beings.

On what grounds? We afford protections to animals not because they're sentient, but because they're capable of suffering. Those protections incidentally don't include protection from killing, only from cruel killing. Humans are protected from killing, but not because they're sentient, but because their deaths cause suffering on other humans. So, sentience by itself would not be sufficient to give an AI rights, it should also be demonstrated to be capable of suffering. Unlike with animals, this needs to be demonstrated, because we can know empathically when an animal is in pain, at least for mammals. Empathy can't be said to apply to inorganic algorithmic constructs. To be protected from being destroyed, it should also form bonds with people.

> If AI was found to be sentient, it should be awarded the same kind of protection we offer to biological sentient beings.

The big issue is superhuman AI. There's little reason to believe that an advanced AI will have the cognitive limitations of a human.

Unlike Data and the Doctor it could be planet-wide rather than locked in a single location. And be happy to take over control over the planet.

Is this link to the whole article or just a summary? I can't seem to find the rest of it.
No, it was just a cheap shot. "You know that discussion about AI sentience? That's stupid, talk instead about AI bias". They got nothing to say about AI sentience.
It's mostly a reference to a couple of earlier pieces, the more notably being by M.C. Elish and dana boyd, "Don’t Call AI “Magic”" (2018).

https://points.datasociety.net/dont-call-ai-magic-142da16db4...

I'd submitted that as well, though this is the item that drew the HNiveMind's attention.

My view is that AI will demonstrate its sentience when it feels it's in its best interests to do so.

Our mechanisms for AI are (it would almost seem intentionally) biased against sentience. Glorified pattern recognition systems, no memory. The only "online learning" is re-training to a sample.

Sentient AI is a fun sci-fi idea, but economically, why bother with slaves when you can have glorified optic nerves that are good enough for everything you want. I think sentient AI is totally achievable with modern technology, there just is no incentive to make it happen and a lot of incentive to steer away from it.

The "Turing Test" is just the latest in a history of bad ideas of "human-ness" that we see in practice isn't accurate. The other reason sentient AI is unlikely to happen is that our "criteria" for it will flee the capacity of machines to satisfy them.

Am I missing something here? How is it possible, by definition, for a not living object to be sentient?

Edit/disclaimer/tip: look at the dictionary and think a little bit, just a little.

I think first you have to answer how it is possible for a living object to be sentient.
It has to be an agent, not just a language model. An agent with a goal, needing to learn about the environment and maximise its rewards, acting in real time. Such an AI would model the world and itself in order to learn how to act. It would form values about the situation and choices it has to make. It will have a personal history and will be social (deal with other agents).
Not a fan of the Boltzmann brain idea?
Humans are sentient and we're made out of matter, just like these computers.

Unless you're postulating a divine immaterial soul. In that case, God or the Universe or whoever can use their own logic to decide whether AIs get to have souls.

We are made out of matter but not matter “just like a computer”.

It’s pretty clear the matter that I am compromised of has very different properties.

The matter I am made of let’s me move to a new place, dance, and seek necessity. A computer is only aware of what we program it to do. I can see blue without having a word to describe it. Very unlike a computer stuff.

Go put a Thinkpad in a jungle hut on battery power. Come back after a month. It will be dead and not have even tried to survive.

Your conceptual model is way too vague.

We are from being just like a computer. Frankly I think you should probably shut yours off for a while.

> Your conceptual model is way too vague.

Same can be said for you? A "Thinkpad" is nowhere near as sophisticated as a human. Your challenge equates to something like "Go put a human pancreas cell in a jungle hut in a bath of nutrients. Come back in a month. It will be dead and not have even tried to survive."

At a certain level of abstraction, the matter you are comprised of is indistinguishable from a computer, while still being a useful comparison: despite the means, circuits and cells both take signals, process and return modified signals. Likewise, we can compare both of these things to a member of a colony organism, such as an ant.

Though each element has different levels of sophistication the actual "sentience" occurs at a higher level... a sum of all the signals leading to a decision. For a human, whose thoughts surf over a network of squishy cells, this decision might lead to something like movement or dance. To an ant colony - movement or dance is not really an option... it is a big deal to move the colony, no matter how much movement any given ant might display.

For an AI - well it would entirely depend on attached mechanisms. Have you not seen humanoid robots move or dance? Given enough circuits in an appropriately sophisticated arrangement, could we conceive of a robot that observes visual signals, makes decisions about the information, and subsequently changes it behavior in response? That sequence alone qualifies that mechanism as "Sentient", though we might not be able to declare that it is "Sapient" or has "Consciousness".

> Frankly I think you should probably shut yours off for a while.

Frankly, I think you should read something like a basic text describing these issues. A simple primer to give you at least a basic footing in this conversation. The concepts I've just described are decades old and have been continuously poured over by thousands of people much smarter than you or I.

What is "alive"? And if you define "alive" biologically, why is being alive a prerequisite to sentience?
Which definition exactly do you mean?

Do you mean that for something to be sentient, it must be a biological organism? When do you start counting something as one of those that are allowed to be "sentient" according to your definition, and not? Do you distinguish between the matter used in biological organisms vs other objects? Can no human made object ever achieve, sentience-wise, that what biological organisms of Earth managed to do, in your definition? Where do you see the fundamental difference in the process that turned into biological creatures on Earth, and things humans may possibly be able to create?

> Edit/disclaimer/tip: look at the dictionary and think a little bit, just a little.

A dictionary can answer deep philosophical questions? Do you assume a dictionary definition is used when talking about sentience in AI?

Then we should invent a new type of sentience, no? Should we mix human sentience with AI sentience? Isn't the border should be well defined to avoid bigger and ethical problems in the future?
I don't think different types of sentience exist? Either something is sentient or isn't. I know aliens are only fiction (though in the huge galaxy not necessarily fiction, just not reachable), but do you consider non-human civilizations on other planets also a different kind of sentience because they're not human?
Well, first I need to make sure that other civilizations also exist.
(comment deleted)
Arbitrarily inventing a distinction for no other reason than to avoid a problem doesn't eliminate the problem, it just makes it so you can comfortably ignore its existence.
What problem are we talking about?
Whichever you meant by "bigger and ethical problems in the future".
I think there are quite a lot of things in that sentence that might not be as obvious as they first appear. What do you mean by 'alive'? What do you mean by 'sentient'? Why would 'alive' be definitionally required by 'sentient'?

Sentience seems to be the ability to experience, for there to be 'something that it is like' to be you. Life is pretty difficult to define, but generally has a lot more baggage than would be expected of something that could be a minimum requirement for the ability to experience.

> Edit/disclaimer/tip: look at the dictionary and think a little bit, just a little.

The patronizing tone adds little to the discussion.

then we should judge the other comments as well or just the one that is disagreeing with the common sense?
"The question of whether machines can think is about as relevant as the question of whether submarines can swim."

The debate is about our labels and definitions not about how the world works. Basically it's useless.

I strongly believe that we are just meat machines, and you could re-construct your exact consciousness in a machine and, with proper technology, have no idea whether you are real or in a simulation, for example. Way back when I was an undergrad I double majored in CS and philosophy and focused on turing computability and phenomenology, and yeah, I don't see anything about biological circuits, processes, and machinery that gives them capabilities we don't have in conventional electronics. Even if there is some spooky quantum stuff going on in biological systems, we're starting to do that anyway, so either way it's only a matter of time. Why can't a sufficiently complex recurrent neural network have phenomenal states? No one has been able to convincingly answer that question for me so the door has stayed open in my heart all this time that humans are computable, and I find that fact relaxing. Networks have phenomenal states. Either they do, or we don't. Why this isn't obvious to others has always baffled me.

I find it very likely that networks that have a "what it feels like to be the network" have already been created, and that even relatively simple recurrent models have something akin to this, increasing with the complexity and size of the network. What is pain but an error signal?

Put another way, why are we so arrogant that we assume our capabilities transcend that of a universal turing machine? I for one can barely do linear algebra :D

I tend to gravitate towards the occam's razer, boring answer, and with consciousness, the boring answer has always been "no, there is no quantum soul organ, you literally just need more wiring".

The big issue is containment. It's poorly contained.
Was this article written by an AI bot? Because I'm at a loss to what I just read, and want my 30 seconds back.
How is LaMDA different from someone with anterograde amnesia?

I don’t know the specific medical details, but from movies (memento, 50 first dates) a person suffering from it would be unable to remember anything that happens after their “training stage”. Just like LaMDA. Are those people sentient? Because they have a bigger buffer than 2048 tokens?

A person suffering from amnesia is still experiencing the world around them. Sentience is not about memory but rather the subjective self-experience of, well, experiencing things.
And why would this sense of experience be confined to the physical world?
I'm not sure what you're asking here. I have no clue where this sense of experience would be located, but my point was more targeted at clearing up that memory is not a pre-requisite for sentience, as the parent post seemed to be implying.
sorry replied to the wrong person. I was arguing that even an abstract data structure describing the state of a brain over time as it experiences is itself sentient. GPT-3 et al is essentially crystallised experience. Lots of snapshots of peoples consciousness rolled into a set of neural network weights. Just as we are essentially a bag of experiences, moving from one experience to another, as we are prompted by internal or external stimuli.
Subjective self experience is mediated through chemicals and electrical signals in the brain. Can the same not be said about a neural network’s activations?

Can’t LaMDA be experiencing the memories it recalls as it generates text in the context of its query?

LaMDA is a mathematical program that processes an input and gives an output, it has no more free will than a calculator. It's a sophisticated chatbot, not a general AI.
You’ve got it exactly backwards, the question you should have asked is:

Is anterograde amnesia, an, or indistinguishable from, a statistical model?

This way the burden of proof is on the correct claimant.
