The year is 2100. Geena is the proud new owner of Emit, a state-of-the-art robot. She has just unwrapped him, the packaging strewn across the dining room floor. Emit is designed to replicate the outward behaviour of a human being down to the last detail (except that he is rather more compliant and obedient). Emit responds to questions in much the same way humans do. Ask him how he feels and he will say he has had a tough day, has a slight headache, is sorry he broke that vase, and so on. Geena flips the switch at the back of Emit's neck to ‘on’. Emit springs to life.
