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.

I want to tell mayors, county chiefs and heads of big companies: don't just chase GDP growth; don't chase the biggest profits at the expense of our children and grandchildren and at the cost of sacrificing our ecological environment.

I'm one of those people who is colour blind to a certain degree. And that doesn't mean I'm not acutely aware of race in our country and abroad and in the world. I know what's going on, and I'm very aware of it.
