AI might follow the path of a normal technology like the motor car which was fairly normal in itself but which had a dramatic effect on the rival solution of horses used for transport. It may have an unusual effect on humans because we are like the horses in this analogy.

The authors themselves use the analogy of electric motors, which changed factories. But also gave us washing machines, refigerators, and vacuum cleaners, changing society. And skyscrapers, because elevators, changing cities.

Ai may be more like electricity than just electric motors. It gave us Hollywood and air travel. (Before electricity, aluminum as as expensive as platinum.)

Maybe.
