Ah... Furby... John kind of remembers what that is, but he was in the Army at the time. Some guys talked about how their kids had them or wanted them. Some sort of talking toy. Nothing close to what Aurora is. It gives him a starting point.

"Assuming Aurora functions how I'd expect, she's essentially a computer that's capable of processing information far beyond what a human can. She has the ability to understand human speech, though it's impossible to say if she's capable of understanding the full range of what you or I would consider 'emotions'. And it wouldn't be a stretch to believe that she's observing and analyzing everything we do, even when she's not with us. Hidden cameras and microphones, all reporting back to her, and because she's a super computer she can process all the data at once."

It's a lot to process and he's been talking a lot, so he pauses there to let Will catch up with this revelation. John had gotten used to being observed by the Machine, had even come to be comforted somewhat by Harold's own watchful gaze. He feels only cold dread knowing that Aurora is likely doing the same right now.
