No one suggests that writing about science will turn the entire world into a model of judgment and creative thought. It will be enough if they spread the knowledge as widely as possible.

Any teacher that can be replaced by a computer should be replaced by a computer.

I, on the other hand, am a finished product. I absorb electrical energy directly and utilize it with an almost one hundred percent efficiency. I am composed of strong metal, am continuously conscious, and can stand extremes of environment easily.
