In our kitchen we have a refrigerator. This is a familiar first world luxury. It's 15 years old. Within any reasonable tolerance it does exactly what we bought it for and, barring the need to change the light bulb (IotT not required), it works just fine.
Fast forward to CES; refrigerators that open at the brush of a foot but sensitive enough to know the difference between human and canine paws. Refrigerators with cameras, sensors, tablets and wifi that alert you to freshness and quantity and re-order when stocks are low.
