If AI Ever Becomes Sentient, It Will Let Us Know

What we humans say or think isn’t necessarily the last word on artificial intelligence. 

How will we know?

Blake Lemoine, a senior software engineer in Google’s Responsible AI organization, recently made claims that one of the company’s products was a sentient being with consciousness and a soul. Field experts have not backed him up, and Google has placed him on paid leave.

Lemoine’s claims are about the artificial-intelligence chatbot called laMDA. But I am most interested in the general question: If an AI were sentient in some relevant sense, how would we know? What standard should we apply? It is easy to mock Lemoine, but will our own future guesses be much better?
