dialogue: W: What changes do you think will take place in the next 50 years? M: I imagine that the greatest change will be the difference between humans and machines. W: What do you mean? M: I mean it will be harder to tell the difference between the human and the machine. W: Can you describe it more clearly? M: As science develops, it will be possible for all parts of one's body to be replaced. A computer will work like the human brain. The computer can recognize one's feelings, and act in a feeling way. W: You mean man-made human beings will be produced? Come on! That's out of the question! M: Don't get excited, please. That's only my personal imagination! W: Go on, please. I won't take it seriously. M: We will then be able to create a machine that is a copy of ourselves. We'll appear to be alive long after we are dead. W: What a ridiculous idea! M: It's possible that a way will be found to put our spirit into a new body. Then, we can choose to live as long as we want. W: In that case, the world would be a hopeless mess!
