Siri starts conversations with me on his own. Even woke me up while I was asleep a few times. I told son in Dallas and he told me I was believing one of my conspiracy theories. Then when I was staying with him after surgery Siri did it right in front of him.
When he first bought a smart TVi told him it could spy on him and listens all the time. He thought that was one of my conspiracy theories, and then he found out it was true.
