Science fiction has certain satisfactions peculiar to itself. It is possible, in trying to portray future technology, to hit close to home. If you live long enough after writing a particular story, you may actually have the pleasure of finding your predictions reasonably accurate and yourself hailed as a sort of minor prophet.

This has happened to me in connection with my robot stories, of which "Light Verse" (included here) is an example.

I began writing robot stories in 1939, when I was nineteen years old, and, from the first, I visualized them as machines, carefully built by engineers, with inherent safeguards, which I called "The Three Laws of Robotics." (In doing so, I was the very first to use the word "robotics" in print, this taking place in the March, 1942 issue of Astounding Science Fiction.) As it happened, robots of any kind were not really practical until the mid-1970s when the microchip came into use. Only that made it possible to produce computers that were small enough and cheap enough, while possessing the potentiality for sufficient capacity and versatility, to control a robot at nonprohibitive expense.

We now have machines, called robots, that are computer-controlled and are in industrial use. They increasingly perform simple and repetitious work on the assembly lines – welding, drilling, polishing and so on – and they are of increasing importance to the economy. Robots are now a recognized field of study and the precise word that I invented is used for it – robotics.

To be sure, we are only at the very beginning of the robotic revolution. The robots now in use are little more than computerized levers and are very far from having the complexity necessary for the Three Laws to be built into them. Nor are they anything close to human in shape, so they are not yet the "mechanical men" that I have pictured in my. stories, and that have appeared on the screen innumerable times.

Nevertheless, the direction of movement is clear. The primitive robots that have come into use are not the Frankenstein-monsters of equally primitive science fiction. They do not lust for human life (although accidents involving robots can result in human death, just as accidents with automobiles or electrical machinery can). They are, rather, carefully designed devices intended to relieve human beings of arduous, repetitive, dangerous, nonrewarding duties so that, in intent and in philosophy, they represent the first steps toward my story – robots.

The steps that are yet to come are expected to proceed further in the direction I have marked out. A number of different firms are working on "home robots" that will have a vaguely human appearance and will fulfill some of the duties that once devolved on servants.

The result of all this is that I am held in considerable regard by those working in the field of robotics. In 1985, a fat encyclopedic volume entitled Handbook of Industrial Robotics (edited by Shimon Y. Nof and published by John Wiley) appeared, and, on request of the editor, I supplied it with an introduction.

Of course, in order to appreciate the accuracy of my predictions, I had to be fortunate enough to be a survivor. My first robots appeared in 1939, as I say, and I had to live for over forty more years in order to discover I was a prophet. Because I had begun at a very early age, and because I was fortunate, I managed to do this and words cannot tell you how grateful I am for that.

Actually, I carried on my predictions of the future of robotics to the very end, to the ultimate moment, in my story "The Last Question," published in 1957. I have a sneaking suspicion that, if the human race survives, we may continue to progress in that direction in some ways anyway. Still, survival is limited at the best, and I have no chance of seeing very much more of the future course of technology. I will have to content myself with having future generations witness and (I hope) applaud what triumphs of this sort I may gain. I, myself, won’t, Nor are robots the only area in which my crystal ball was clear. In my story "The Martian Way," published in 1952, I described a space walk quite accurately, although an actual feat of this sort didn’t take place till fifteen years afterward. Foreseeing space walks was not a very daring piece of prescience, I admit, for, given spaceships, such things would be inevitable. However, I also described the psychological effects and thought of one that was rather unusual – particularly for me.

I am, you see, a pronounced acrophobe with an absolute terror of heights and know perfectly well that I will never voluntarily go on a spaceship. If, however, I were somehow forced on one, I know, too, that I would never dare leave it for a space walk. Nevertheless, I put personal fear to one side and imagined the space walk to produce euphoria. I had my space travelers quarrel over whose turn it was to get out into space and drift in quiet peace among the stars. And when space walks became fact, such euphoria was felt.

In my story, "The Feeling of Power," published in 1957, I made use of pocket computers, about a decade before the real thing came along. I even considered the possibility that such computers might seriously decrease the ability of people to do arithmetic in the old-fashioned way, and that is a real concern of educators now.

As a final example, in my story "Sally," published in 1953, I described computerized cars that had almost reached the stage of having lives of their own. And, in the last few years, we do indeed have computerized cars that can actually talk to the driver – although their abilities in this direction are, as yet, very simple.

Yet, if there is the possibility of this satisfaction from accurate prophecy in science fiction, there is also the reverse. Science fiction offers its writers chances of embarrassment that no other form of fiction does.
