Lemoine worked for Google’s Responsible AI organization and, as part of his job, started talking to LaMDA, the company’s artificial intelligence system for building chatbots, in the fall. He came to believe the technology was sentient after signing up to test whether artificial intelligence could use discriminatory or hate speech.

In a statement, Google spokesman Brian Gabriel said the company takes AI development seriously and has reviewed LaMDA 11 times, as well as released a research paper detailing responsible development efforts.
“If an employee shares concerns about our work, as Blake did, we review them thoroughly,” he added. “We found Blake’s claims that LaMDA is sentient to be completely unfounded and worked to clarify this with him for many months.”
He attributed the talks to the company’s open culture.
“It is unfortunate that despite a long engagement on this topic, Blake has still chosen to persistently violate clear employment and data security policies that include the need to protect product information. “Gabriel added. “We will continue our careful development of the language models, and wish Blake well.”
Lemoine’s dismissal was first reported in the Big Tech Newsletter.
At Lemoine’s interviews with LaMDA sparked widespread discussion about recent advances in AI, public misunderstanding of how these systems work, and corporate responsibility. Google previously expelled Ethical AI division chiefs Margaret Mitchell and Timnit Gebru after they warned of the risks associated with the technology.
Google hired Timnit Gebru to openly criticize unethical AI. Then she was fired for it.
LaMDA uses Google’s most advanced large language models, a type of AI that recognizes and generates text. These systems cannot understand language or meaning, the researchers say. But they can produce deceptively human-like speech because they’re trained on huge amounts of data crawled across the internet to predict the most likely next word in a sentence.
After LaMDA spoke to Lemoine about the personality and his rights, he began to investigate further. In April, he shared a Google Doc with senior executives titled “Is LaMDA Sentient?” which contained some of his conversations with LaMDA, where he claimed to be sensitive. Two Google executives reviewed his claims and dismissed them.
Big Tech is building AI with bad data. So scientists looked for better data.
