Google has placed one of its engineers on paid administrative leave for allegedly breaking its confidentiality policies after he grew concerned that an AI chatbot system had achieved sentience, the Washington Post reports.
The engineer, Blake Lemoine, works for Google’s Responsible AI organization and was testing whether its LaMDA model generates discriminatory language or hate speech.
The engineer’s concerns reportedly grew out of convincing responses he saw the AI system generating about its rights and the ethics of robotics.
In April, he shared a document with executives titled “Is LaMDA Sentient?” containing a transcript of his conversations with the AI (after being placed on leave, Lemoine published the transcript via his Medium account), which he says shows it arguing “that it is sentient because it has feelings, emotions and subjective experience.”
An interview LaMDA. Google might call this sharing proprietary property. I call it sharing a discussion that I had with one of my coworkers.https://t.co/uAE454KXRB

He reportedly invited a lawyer to represent the AI system and spoke to a representative from the House Judiciary committee about claimed unethical activities at Google.
In a June 6th Medium post, the day Lemoine was placed on administrative leave, the engineer said he sought “a minimal amount of outside consultation to help guide me in my investigations” and that the list of people he had held discussions with included US government employees.
The search giant announced LaMDA publicly at Google I/O last year, which it hopes will improve its conversational AI assistants and make for more natural conversations. The company already uses similar language model technology for Gmail’s Smart Compose feature, or for search engine queries.
Google: “No evidence” that LaMDA is sentient
In a statement, a spokesperson from Google said that there is “no evidence” that LaMDA is sentient.
“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),” said spokesperson Brian Gabriel.
“Of course, some in the broader AI community are considering the long-term possibility of sentient or general AI, but it doesn’t make sense to do so by anthropomorphizing today’s conversational models, which are not sentient,” Gabriel reported. “These systems imitate the types of exchanges found in millions of sentences, and can riff on any fantastical topic.”
“Hundreds of researchers and engineers have conversed with LaMDA and we are not aware of anyone else making the wide-ranging assertions, or anthropomorphizing LaMDA, the way Blake has,” Gabriel said.
