My Roomba's name is Roswell. There is the moment when you are sitting on the couch and Roomba turns itself on and goes out and starts working. You really appreciate it because it works hard for you, and it deserves some kind of recognition.

When my daughter was 3, she was eating Cheerios and spilled some on the table. So she swiped them onto the floor. I said, 'Darcy, what are you doing?' She said: 'Don't worry, Daddy, the robot will get it.' I didn't know whether to be horrified or proud. It was this idea that homes take care of themselves and robots are part of that.

Though builders may build, in the main they follow the plans of architects. Teachers teach, but they must have a text. Politicians govern, but only upon the flow of commentary that raises them up or casts them down.

Early in the 1990s, I flew alone in a dandelion-yellow, single-engine, 180-horsepower Piper Cherokee from Westchester County Airport in New York westward to the Rocky Mountains, landing and refuelling a good many times in middle-sized cities and towns along the way.
