Thinking, Feeling machines

The article says that in his several stories, Ray Bradbury explored artificial intelligence. He thought about the philosophical implications of AI advanced enough to possibly produce machines that can feel and think. I can't imagine if we will ever have them or what on earth would happen if we ever did. I don't even know one fifth of what the writer knew. But I would say that there might be a problem when disposing of them. If robots actually thought, felt and talked alomst the same as human beings and we made nice friends with them, I don't think we could power them off completely and throw them in dumps and go buy the latest models without feeling any guilt. what do you think about a society with thinking, feeling machines?
