I don't know if you are aware, but scientists are creating some pretty realistic android robots these days. There are even robots that they are being taught to learn in the same way that a young child learns.
The implications of these facts remind me of the movie "Terminator." Do you think that robots and computers can become too smart and realistic in the future? Check out this video. There are also others on Youtube that are also interesting as well. Let me know what you think.
