Or a personal assistant? As there's potential for rich interactive refinement, as well as learned inference. As with Nest, there's an architectural privacy challenge. You'd like your pa to have insights like "oh, your interests on topic X align closely with other-person, so let's see, maybe you'd like thing too?". Ideally using local or trusted computes. But you don't in general want other-person's pa to know all your things. So perhaps an ecology of trusted visibility? Your pa can run parts of itself on a bonded site, with greater visibility than it would have locally, but with restrictions on what it can report back? But that's hairy and hard. So...?
