On AI’s tipping point…

Last night I watched my wife have a conversation with a computer. Not a particularly sophisticated conversation, as conversations go, but it felt like a conversation to her and that’s perhaps more important.
She has just received a new phone upgrade - an iPhone4S, and, while she was playing around with it on the sofa next to me, I casually asked her whether she realised the phone was intelligent?
“What do you mean?” she said.
