many people who have coined a useful scientific term, and although I did it unknowingly, I have no
intention of letting anyone in the world forget it.
What's more, in "Runaround" I listed my "Three Laws of Robotics" in explicit detail for the first time,
and these, too, became famous. At least, they are quoted in and out of season, in all sorts of places that
have nothing primarily to do with science fiction, even in general quotation references. And people who
work in the field of artificial intelligence sometimes take occasion to tell me that they think the Three Laws
will serve as a good guide.
We can go even beyond that-
When I wrote my robot stories I had no thought that robots would come into existence in my lifetime.
In fact, I was certain they would not, and would have wagered vast sums that they would not. (At least, I
would have wagered 15 cents, which is my betting limit on sure things.)
Yet here I am, forty-three years after I wrote my first robot story, and we do have robots. Indeed,
we do. What's more, they are what I envisaged them to be in a way-industrial robots, created by
engineers to do specific jobs and with safety features built in. They are to be found in numerous factories,
particularly in Japan, where there are automobile factories that are entirely roboticized. The assembly line
in such places is "manned" by robots at every stage.
To be sure, these robots are not as intelligent as my robots are-they are not positronic; they are not
even humanoid. However, they are evolving rapidly and becoming steadily more capable and versatile.
Who knows where they'll be in another forty years?
One thing we can be sure of. Robots are changing the world and driving it in directions we cannot
clearly foresee.
Where are these robots-in-reality coming from? The most important single source is a firm called
Unimation, Inc., of Danbury, Connecticut. It is the leading manufacturer of industrial robots and is
responsible for perhaps one third of all robots that have been installed. The president of the firm is Joseph
F. Engelberger, who founded it in the late 1950S because he was so interested in robots that he decided
to make their production his life work.
But how in the world did he become so interested in robots so early in the game? According to his
own words, he grew interested in robots in the 1940s when he was a physics-major undergraduate at
Columbia University, reading the robot stories of his fellow Columbian Isaac Asimov.
My goodness!
You know, I didn't write my robot stories with much in the way of ambition back in those old, old
days. All I wanted was to sell them to the magazines in order to earn a few hundred dollars to help pay
my college tuition-and to see my name in print besides.
If I had been writing in any other field of literature, that's all I would have attained. But because I was
writing science fiction, and only because I was writing science fiction, I-without knowing it-was starting a
chain of events that is changing the face of the world.
Joseph F. Engelberger, by the way, published a book in 1980 called Robotics in Practice:
Management and Application of Industrial Robots (American Management Associations), and he was
kind enough to invite me to write the foreword.
