Well, we talk back to them of course. That day is already here and not just for us geeks. Every smartphone (well at least the iPhone and Windows Phone) talk to you and listen to you. I have never tried an Android, but my guess is that they have the capability as well. It isn't like the computer on Star Trek, but as Neil Armstrong stated over 40 years ago, 'It is a great leap for mankind' and it is going to get better. Real soon.
