    As a result, the modern world is increasingly populated by intelligent gizmos whose presence we barely notice but whose universal existence has removed much human labor.Our factories hum to the rhythm of robot assembly arms.Our banking is done at automated teller terminals that thank us with mechanical politeness for the transaction.Our subway trains are controlled by tireless robot-drivers.And thanks to the continual miniaturization of electronics and micro-mechanics, there are already robot systems that can performsome kinds of brain and bone surgery with submillimetre accuracy—【T5】______canachieve with their hands alone.
    But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least a few decisions for themselves—【T6】______."While we know how to tell a robot to handle a specific error,"says Dave La very, manager of a robotics program at NASA, "we can’t yet give a robot enough ’common sense* to reliably interact with a dynamic world."
