Will our robot pets spy on us?

At $2,900, Sony's robot dog Aibo sits at the fringe of technology, but it might not stay there. Whether you find it cute or creepy, the tech that makes Aibo tick is continuing to evolve, and it isn't hard to imagine a whole litter of less expensive Aibo competitors aimed at consumers -- and even at children -- in the not-so-distant future. To be clear, Aibo's tech already includes artificial intelligence, sensors and microphones that help it interact with people, and cameras that can recognize faces and help it navigate your home like a Roomba. A reasonable consumer might rightly wonder just how much data this dog gathers as it wanders their home scanning faces and learning about its owners. Perhaps more important -- what exactly does Sony do with that data?
