What are the two speakers talking about?

W: Will you tell us about the new intelligent house your company has built? It promises to be a model for houses of the future.
M: Certainly. The idea is not to have a house full of gadgets. This is a complete household system. It will make people’s lives easier.
W: OK. So tell me how this house will make my life easier?
M: When you arrive at the front door, you won’t need a key. The door will open with atouch of your finger: the system recognizes your fingerprint. You’ll be able to call your refrigerator when you’re in the supermarket and find out how much milk you still have and figure out how much you need to buy. Isn’t that wonderful?
W: Can I call the washing machine as well?
M: Sure. But you won’t need to. The house comes with a robot.
W: What about household problems?
M: Well, if a pipe bursts, the house will call the plumber. And if there’s a fire, the house will turn on the fire extinguishers automatically and call the fire department.
W: And what’s the price of this intelligent house?
M: A million dollars.
W: A million dollars! It will be the 22nd century before I’ll be able to afford one.
