What changes do you think will take place in the next 50 years?
I imagine that the greatest change will be the difference between humans and machines.
What do you mean?
I mean it will be harder to tell the difference between the human and the machine.
Can you describe it more clearly?
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.
You mean man-made human beings will be produced? Come on! That's out of the question!
Don't get excited, please. That's only my personal imagination!
Go on, please. I won't take it seriously.
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.
What a ridiculous idea!
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.
