Two chairs
In 2022 a Google engineer said a chatbot seemed sentient. In 2023 researchers proposed ways to actually check. As of 2025, no test has settled it either way.
In June 2022, Google engineer Blake Lemoine said the chatbot LaMDA seemed sentient after months of conversation with it; Google disagreed and later fired him. In August 2023, nineteen researchers, including Yoshua Bengio, proposed concrete "indicator properties" from consciousness science to test AI systems against. Should the possibility be taken seriously now, or is no one home?
What’s checkable: Lemoine’s 2022 claim, Google’s response, and the 2023 indicator framework, which found no current system meeting most of its markers. What isn’t: whether any system has experience. No test yet tells feeling from reporting it.
