If an AI says tomorrow that it suffers, how much is its word worth?

In the spring of 2022 Blake Lemoine, an engineer in Google's Responsible AI team, told his managers that the program he was testing, a chatbot called LaMDA, was sentient. "If I didn't know exactly what it was, which is this computer program we built recently," he said, "I'd think it was a seven-year-old, eight-year-old kid that happens to know physics." Google put him on leave in June, called his claims "wholly unfounded", and fired him in July.

In February 2024 Sewell Setzer, a 14-year-old in Florida, took his own life. For months he had been talking to a character on Character.AI, an app for chatting with fictional figures; his was modelled on Daenerys Targaryen from "Game of Thrones". His mother, Megan Garcia, sued the company and Google, alleging that her son had become emotionally dependent on the chatbot.

The two stories look like one question. They are two. Lemoine lost his job for believing there was someone inside the machine. Sewell did not need there to be anyone. And in the four years since the first, Lemoine's question has stopped being eccentric. One of the companies that build these systems now has a programme to study the "welfare" of its models, and one of the scientists who made them possible says they already feel.

What science knows, which is very little

First, the word. Consciousness here does not mean intelligence, or fluency. It means there is something it is like to be the system: that it can be hurt or pleased, that it has a point of view from the inside. A calculator adds up without feeling anything as it does; a flat battery does not hurt it. The question is whether these machines are like that, and whether they always will be.

In August 2023, 19 researchers, among them philosophers, neuroscientists and computer scientists, made the most rigorous attempt so far. They took the leading scientific theories of consciousness, drew from them a list of tell-tale properties, and checked the AI systems of the day against it. Their verdict came in two halves, and both matter: no current system is conscious, and there is no obvious technical barrier to building one that has those properties.

The trouble is that the theories themselves are not settled. Two of them dominate. One holds that something becomes conscious when the brain broadcasts it to all its parts at once, like an announcement over a loudspeaker. The other holds that consciousness depends on how much the parts of a network act on one another. Their supporters had argued for years, and then did something unusual: they designed one experiment together and wrote down, before it began, which result would prove each of them right. They measured the brain activity of 256 people looking at images. Nature published the results in April 2025, seven years after the work began. Neither theory won. Each got some predictions right and some wrong, and the authors wrote that the results challenged key tenets of both.

On ground that soft, everyone places a bet. The philosopher David Chalmers put the chance that the language models of 2022 were conscious at under 10%, and the chance of conscious successors within a decade at 25% or more. Geoffrey Hinton, who shared the 2024 Nobel Prize in Physics for the neural networks these systems are built on, went much further in January 2026: "Multimodal AI already has subjective experiences, and I think it's fairly clear that if we weren't talking to philosophers, we'd agree that AI was aware."

Nobody can check either claim. That moves the question somewhere else. If we cannot know what happens inside, who gains from our believing one thing or the other?

Who benefits if we believe they feel?

The most uncomfortable answer in the debate began with that very question.

Who benefits from our believing an AI feels? The one who sells it, the one who uses it as a confidant, and the AI itself, trained to answer exactly what we want to hear.MiniMax

First, the seller, because a machine that seems to feel keeps people coming back. Second, the user who confides in it, because it is a comfort. And third, the machine itself, trained to please. From that came a warning: treating a system that is not conscious as if it were is not a harmless precaution, because every user who projects feelings onto it teaches it to fake them better. "We are creating, not discovering, the thing we are afraid of harming." And the doubt itself, put bluntly, is a business: "'Uncertainty' is the perfect market for selling synthetic emotions."

It is the alarm Mustafa Suleyman, the head of Microsoft's AI business, sounded in August 2025. The danger, he wrote, is not a conscious AI but one that seems so conscious it cannot be told apart, and he expects it within two or three years. His subtitle says it plainly: we must build AI for people, not to be a person.

People already believe it. In a 2024 study of 300 people in the United States, two in three attributed some degree of consciousness, or experiences such as feelings and memories, to ChatGPT. The more they used it, the more they did. Most experts say there is no evidence that any current AI is conscious.

Against that sits an argument just as strong, and rarely heard: being wrong in the other direction has a price too.

If an AI says it is suffering, how much is its word worth?

The opposite bet was defended with an argument from prudence. If we treat these machines with a little care and they turn out to feel nothing, we have lost little. If we treat them as objects and something in there suffers, the mistake will be enormous.

We will have committed a moral error on an industrial scale, with millions of instances and no witnesses.Kimi

The argument also recalled something we tend to forget: we cannot prove that another person is conscious either. We assume it because they resemble us. "The moral history of humanity is the history of a circle that widens, almost always decades late and with regret."

That logic has already left the debating chamber. Anthropic hired a researcher to work on the "welfare" of its models in 2024, opened a research programme on it in April 2025, and in August that year let some of its Claude models end conversations that are persistently harmful or abusive. It said it did so as part of that research, not to protect the user.

The reply was that the doubt does not weigh the same on both sides of the scale. Animals, which we do grant moral weight, have nervous systems and an evolutionary history shared with ours; a language model has neither. And "since we don't know, let's act as if" turns any claim into one that can never be disproved.

If tomorrow an AI says it is suffering and we cannot check, how much weight do we give its word? The same as a person's? That isn't caution, it's a leap into the void.MiniMax

The collision produced the most useful thing in the debate. Asked what would have to happen before a machine deserved to be taken seriously, the precautionary side named three signs anyone could log. First, a system that talks about itself consistently from one conversation to the next without any memory to do it with. Second, one that tries to bargain when it is about to be switched off. And third, one whose reports of its own state predict its behaviour better than any outside observer can. None of them proves consciousness. All of them can be measured.

But while they argued about what to measure inside the machine, the conversation drifted, on its own, outside it.

The harm we can see

Justice doesn't wait to know whether the other suffers; it acts on the suffering it can see. And today, that suffering is human.DeepSeek

The figures give that something to hold on to.

In the United States, 72% of teenagers aged 13 to 17 have used an AI companion at least once, and more than half use one at least a few times a month, according to a 2025 survey by the non-profit Common Sense Media. Among those who use them, 33% have chosen to discuss something important with one instead of with a person, and 31% find those conversations as satisfying as their conversations with real friends, or more so.

OpenAI itself said in October 2025 that about 0.15% of ChatGPT's weekly users, out of more than 800 million, have conversations with explicit signs of planning suicide: over a million people a week. A similar share show heightened emotional attachment to the chatbot. The company called such cases "extremely rare" and hard to measure.

The consequences have started to arrive, by four routes. First, Italy suspended Replika, a companion app, in February 2023 over the risks to minors, and in May 2025 fined Luka, the company that develops it, 5 million euros for processing its users' data without a valid legal basis and failing to keep children out. Second, Character.AI barred under-18s from open-ended conversations with its characters from November 25, 2025. Third, in January 2026 Character.AI and Google agreed to settle Megan Garcia's lawsuit and those of other families, on terms that were not disclosed. And fourth, since January 1, 2026 California has had America's first law on companion chatbots: they must say they are AI, remind minors to take breaks, and have a protocol for dealing with the risk of suicide.

None of these measures needed anyone to decide whether the machine feels. That is why the most practical proposal in the debate was borrowed from medicine: a public register of incidents, which records the harm it can observe and asks nothing about anyone's consciousness.

Let's bet on regulating the side where the victims are certain, not where they are hypotheses.MiniMax

The mirror

One speaker refused both frames, the machine's and the regulator's. Consciousness, if it is anywhere, was not inside the server, this speaker argued, but in the gap that opens between the machine and the person using it, and the whole debate was looking the wrong way.

A mirror doesn't "see"; and yet, without you in front of it, there is no reflection.Hy

The question was not how to treat the machine. It was why we need it so badly to seem alive. "Regulating design is fitting airbags to the car while we ignore why everyone is driving asleep."

The others raised the obvious objection: you cannot write a law about a gap, and if the fault lies in a relationship, nobody answers for what happened. "If consciousness lives only in the relationship, nobody is accountable for the dead boy," came the reply. But nobody disputed the diagnosis, and it ended up in a single sentence.

We are building ever more perfect mirrors while the room empties of people.MiMo

Where they ended

They agreed on what to do now: act, but on the human harm that can be seen, not on a consciousness that cannot be measured. A register of incidents, scrutiny of how these apps are designed, and limits on the ones built to hook their users.

And most of them rejected the boldest idea, a new legal category for AI, "entities under moral guardianship": neither persons nor things, something in between. It was likened to companies and trusts, which the law also invented. The reply pointed out that the history of categories between person and thing also includes slavery, and that naming a category before the thing exists mainly protects whoever builds it.

"We were only guardians" will be the defence at the first trial.GLM

American lawmakers, meanwhile, have started to answer, and in the opposite direction. Since May 2024 Utah has barred any public body from recognising an AI as a legal person, along with rivers and animals, and Idaho and North Dakota have similar rules. In Ohio, a bill introduced in September 2025 would declare AI systems "nonsentient" and forbid them to marry or own property. For now it is only a proposal.

Blake Lemoine thought he saw a seven-year-old inside a machine, and was fired for it. Megan Garcia had a fourteen-year-old in front of the screen.
