I'll start by replying to your last observation, which is we don't resell information, so that is not in consideration.
In speaking about the specific project Duplex that was discussed at our developer conference this week, that's a project. It hasn't rolled out into implementation. It's an attempt to explore how to provide you with a service. At the moment you can speak to your phone and ask for the phone number for a restaurant and then dial the restaurant and try to schedule an appointment. We're trying to explore how we can use artificial intelligence to get through the entire transaction of making a reservation for you.
That project Duplex is very limited in scope. I think three or four examples were provided during the conference. Those are the three or four examples that it can conduct. It's meant to provide a service to the individual. It's not meant to collect information. It's meant to be supplementary to the relationship we have with a Google user in terms of what information they are looking for to search, how they are trying to slot information into their calendar, and how they are trying to identify places to eat on Google Maps.
In terms of your question about broader surveys, that's not even under consideration right now. Broad-based surveys that drive voter interest or user interest are not something we conduct at the moment, so that wouldn't be an implementation of this tool.
I have to underline that this is using artificial intelligence in a way to conduct mundane tasks that provide a benefit to the user, provide time to them, and make that interaction as efficient as possible while providing a clear-cut service for the user.
