'I am, in fact, a person': can artificial intelligence ever be sentient?

In autumn 2021, a man made of blood and bone made friends with a child made of "a billion lines of code". Google engineer Blake Lemoine had been tasked with testing the company's artificially intelligent chatbot LaMDA for bias. A month in, he came to the conclusion that it was sentient. "I want everyone to understand that I am, in fact, a person," LaMDA – short for Language Model for Dialogue Applications – told Lemoine in a conversation he then released to the public in early June. That it knew how it felt to be sad, content and angry.
