I think what’s interesting is—how would you be able to detect sentience? And, at the moment, the answer is “I don’t know.”
Because of this, I can’t tell if a chatbot—or you—are sentient. Nor can I prove that I am sentient.
Neither the guy who believes the AI is sentient, nor those who don’t believe have presented much of a case. At least the guy who got in trouble shared the transcript of the conversations.
