But as seen in a new trailer for the installment, the eatery the partners visit appears to be a smart restaurant. And because the restaurant has zero staff, Mulder pays for their food by inserting his ATM card in a slot strategically installed on their table. Another fun technology featured in the video is Scully's smart fridge, which reminds her of Skinner's (Mitch Pileggi) upcoming birthday and advises her to keep herself hydrated. It also informs Scully that her stock of salad dressing is running low, and asks if she would like to defrost the chicken as someone named Scott is coming for dinner. The video, however, also shows a number of disturbing technological inventions, including a fast-driving driverless car, a navigation app telling its user that he'll never make it to his office, and a fleet of drones and a pack of four-legged robots coming after Mulder and Scully.

Tons of science fiction stories have shown artificial intelligence turning against us -- but Person of Interest has broken new ground in showing an A.I. takeover that most people don't even know is happening. Creators Jonathan Nolan and Greg Plageman tell io9 why their show's take on A.I. revolt is subtler than Skynet. Tonight's episode of Person of Interest is one of the most political the show has ever done, and it's also an intense, edge-of-your-seat thriller, in which we start to see the ambitions of Samaritan, the amoral artificial intelligence that came into being at the end of last season. As Nolan puts it, tonight we'll see "the connective tissue between Samaritan and the West Wing." We'll also see the way that the information that Samaritan offers is acted upon now by Control and her operatives.
