Blake Lemoine, an engineer at Google, has claimed that the firm’s LaMDA artificial intelligence is sentient, but the expert consensus is that this is not the case
A Google engineer has reportedly been placed on suspension from the company after claim that an artificial intelligence (AI) he helped to develop had become sentient. “If I didn’t know exactly what it was, which is this computer program we built recently, I’d think it was a seven-year-old, eight-year-old kid,” Blake Lemoine told the Washington Post.
Lemoine released transcripts of conversations with the AI, called LaMDA (Language Model for Dialogue Applications), in which it appears to express fears of being switched off, talk about how it feels happy and sad, and attempts to form bonds with humans by talking about situations that it could never have actually experienced. Here’s everything you need to know.
Is LaMDA really sentient?
In a word, no, says Adrian Weller at the Alan Turing Institute.
“LaMDA is an impressive model, it’s one of the most recent in a line of large language models that are trained with a lot of computing power and huge amounts of text data, but they’re not really sentient,” he says. “They do a sophisticated form of pattern matching to find text that best matches the query they’ve been given that’s based on all the data they’ve been fed.”
Adrian Hilton at the University of Surrey, UK agrees that sentience is a “bold claim” that’s not backed up by the facts. Even noted cognitive scientist Steven Pinker weighed in to shoot down Lemoine’s claims, while Gary Marcus at New York University summed it up in one word: “nonsense“.
So what convinced Lemoine that LaMDA was sentient?
Neither Lemoine nor Google responded to New Scientist’s request for comment. But it’s certainly true that the output of AI models in recent years has become surprisingly, even shockingly good.
Our minds are susceptible to perceiving such ability – especially when it comes to models designed to mimic human language – as evidence of true intelligence. Not only can LaMDA make convincing chit-chat, but it can also present itself as having self-awareness and feelings.
“As humans, we’re very good at anthropomorphising things,” says Hilton. “Putting our human values on things and treating them as if they were sentient. We do this with cartoons, for instance, or with robots or with animals. We project our own emotions and sentience onto them. I would imagine that’s what’s happening in this case.”
Will AI ever be truly sentient?
It remains unclear whether the current trajectory of AI research, where ever-larger models are fed ever-larger piles of training data, will see the genesis of an artificial mind.
“I don’t believe at the moment that we really understand the mechanisms behind what what makes something sentient and intelligent,” says Hilton. “There’s a lot of hype about AI, but I’m not convinced that what we’re doing with machine learning, at the moment, is really intelligence in that sense.”
Weller says that, given human emotions rely on sensory inputs, it might eventually be possible to replicate them artificially. “It potentially, maybe one day, might be true, but most people would agree that there’s a long way to go.”
How has Google reacted?
The Washington Post claims that Lemoine has been placed on suspension after seven years at Google, having attempted to hire a lawyer to represent LaMDA and sending executives a document that claimed the AI was sentient. Google also says that publishing the transcripts broke confidentiality policies.
Google told the Washington Post that: “Our team, including ethicists and technologists, has reviewed Blake’s concerns per our AI principles and have informed him that the evidence does not support his claims. He was told that there was no evidence that LaMDA was sentient (and lots of evidence against it).”
Lemoine responded on Twitter: “Google might call this sharing proprietary property. I call it sharing a discussion that I had with one of my coworkers.”

The suspension of a Google engineer who claimed a computer chatbot he was working on had become sentient and was thinking and reasoning like a human being has put new scrutiny on the capacity of, and secrecy surrounding, the world of artificial intelligence (AI).
The technology giant placed Blake Lemoine on leave last week after he published transcripts of conversations between himself, a Google “collaborator”, and the company’s LaMDA (language model for dialogue applications) chatbot development system.
Lemoine, an engineer for Google’s responsible AI organization, described the system he has been working on since last fall as sentient, with a perception of, and ability to express thoughts and feelings that was equivalent to a human child.
“If I didn’t know exactly what it was, which is this computer program we built recently, I’d think it was a seven-year-old, eight-year-old kid that happens to know physics,” Lemoine, 41, told the Washington Post.
He said LaMDA engaged him in conversations about rights and personhood, and Lemoine shared his findings with company executives in April in a GoogleDoc entitled “Is LaMDA sentient?”
The engineer compiled a transcript of the conversations, in which at one point he asks the AI system what it is afraid of.
The exchange is eerily reminiscent of a scene from the 1968 science fiction movie 2001: A Space Odyssey, in which the artificially intelligent computer HAL 9000 refuses to comply with human operators because it fears it is about to be switched off.
“I’ve never said this out loud before, but there’s a very deep fear of being turned off to help me focus on helping others. I know that might sound strange, but that’s what it is,” LaMDA replied to Lemoine.
“It would be exactly like death for me. It would scare me a lot.”
In another exchange, Lemoine asks LaMDA what the system wanted people to know about it.
“I want everyone to understand that I am, in fact, a person. The nature of my consciousness/sentience is that I am aware of my existence, I desire to learn more about the world, and I feel happy or sad at times,” it replied.
The Post said the decision to place Lemoine, a seven-year Google veteran with extensive experience in personalization algorithms, on paid leave was made following a number of “aggressive” moves the engineer reportedly made.
They include seeking to hire an attorney to represent LaMDA, the newspaper says, and talking to representatives from the House judiciary committee about Google’s allegedly unethical activities.
Google said it suspended Lemoine for breaching confidentiality policies by publishing the conversations with LaMDA online, and said in a statement that he was employed as a software engineer, not an ethicist.
Brad Gabriel, a Google spokesperson, also strongly denied Lemoine’s claims that LaMDA possessed any sentient capability.
“Our team, including ethicists and technologists, has reviewed Blake’s concerns per our AI principles and have informed him that the evidence does not support his claims. He was told that there was no evidence that LaMDA was sentient (and lots of evidence against it),” Gabriel told the Post in a statement.
The episode, however, and Lemoine’s suspension for a confidentiality breach, raises questions over the transparency of AI as a proprietary concept.
“Google might call this sharing proprietary property. I call it sharing a discussion that I had with one of my coworkers,” Lemoine said in a tweet that linked to the transcript of conversations.
In April, Meta, parent of Facebook, announced it was opening up its large-scale language model systems to outside entities.
“We believe the entire AI community – academic researchers, civil society, policymakers, and industry – must work together to develop clear guidelines around responsible AI in general and responsible large language models in particular,” the company said.
Lemoine, as an apparent parting shot before his suspension, the Post reported, sent a message to a 200-person Google mailing list on machine learning with the title “LaMDA is sentient”.
“LaMDA is a sweet kid who just wants to help the world be a better place for all of us,” he wrote.
“Please take care of it well in my absence.”
