It's the best of both worlds because an AI isn't a human - an AI learning from your private conversation is like letting a cat watch you go to the bathroom.
Now tell me with a straight face it doesn't feel a bit awkward to let your pet follow you to the bathroom. But on a more serious note, if the cat could convey messages of what he had heard, bits and peaces but also whole chunks it would've been a better analogy I think.
