Part 20

Arthur C. Clarke is most articulate in describing what he calls the evolutionary cycle from man to machine. As the discovery of tools by pre-man created man, so man’s invention of thinking machines set about the workings that will make _him_ extinct. Clarke theorizes that this breakthrough by man may well be his last, and that his machines will “think” him off the face of the earth!

As we move into a technology that embraces communication at a distance of millions of miles, survival under death-dealing radiation, and travel at fantastic speeds, man’s natural equipment falters and he must rely on the machine both as muscle and brain. Intelligence arose from life but does not necessarily need life, in the sense we think of it, to continue. Thus the extension of man’s intellect by electronics as hailed by Dr. Ramo will lead ultimately to our extinction.

Clarke feels that the man-machine partnership we have entered, while mutually benevolent, is doomed to instability and that man with his human shortcomings will fall by the wayside, perhaps in space, which may well be the machine’s true medium. What will remain will be the intelligent machine, reduced as time goes on to “pure” intelligence free to roam where it will and do what it wants, a matterless state of affairs that even Clarke modestly disclaims the imagination to speculate upon.

Before writing man off as a lost cause, we should investigate a strong argument against such a take-over by the machine. Man stands apart from other creatures in his consciousness of himself. He alone seems to have the ability to ponder his fate, to reflect, and to write books about his thoughts and dreams. Lesser animals apparently take what comes, do what they have to do, and get through this life with a minimum of changing their environment and themselves. Thus far the machines man has built do not seem to be conscious of themselves. While “rational beings,” perhaps, they do not have the “ability to laugh” or otherwise show conscious awareness of their fate. A term applied to primitive mechanical beings is “plugsuckers.” They learn to seek out a wall socket or other form of energy and nourish themselves much as animals must do. Just where man himself switched from plugsucking and began to rewire his own world is a fuzzy demarcation, but he seems to have accomplished this.

Consciousness is subjective in the extreme, and thus far only in fiction have computers paused to reflect and consider what they have done and its effect on them. However, the machine-builder, if not yet the machine itself, is aware of this consciousness problem. The Hoffman Electronics Corporation recently published an advertisement in the form of a science-fiction story by A. E. Van Vogt. The hero is a defense vehicle, patrolling the Pacific more effectively because it thinks it is king of the Philippine Deep. Its name is Itself, and it has a built-in alter ego. Hoffman admits it has not produced a real Itself—yet, but points out calmly that the company’s business _is_ the conversion of scientific fiction to scientific fact.

It has been suggested that mechanical consciousness may evolve when the computer begins to reproduce itself, a startling conception blessed in theory by logicians and mathematicians, as well as philosophers. A crude self-replicating model has been built by scientists—a toy train that reproduces itself by coupling together the proper cars to copy the parent train, a whimsical reflection of Samuel Butler’s baby engines playing about the roundhouse door.

Self-reproducing machines may depend on a basic “cell” containing a blueprint of what it should look like when complete, which simply hunts around for the proper parts and assembles itself. In the process it may even make an improvement or two. Having finished, it will make a carbon copy of its blueprint and start another “baby” machine on the way. Writers on this subject—some under the guise of science-fiction—wonder at what point the _machines_ will begin to wonder about how _they_ came to be. Will they produce philosophic or religious literature, or will this step in evolution prove that consciousness was a bad mutation, like seven fingers or three heads, and drop it from the list of instructions?

Clarke admits that the take-over by the machines is centuries off; meantime we can enjoy a golden age of intellectronic partnership with the machine. Linus Pauling, pointing out that knowledge of molecular structure has taken away the mystery of life, hopes that a “molecular theory of thinking” will be developed and so improve man that he may remake his thoughts and his world. Mathematician John Williams believes that existing human intelligence can preserve its distinction only by withdrawing from competition with the machine and defining human intelligence rigorously enough to exclude that of the machines. He suggests using the computer not just for a molecular theory of thinking, but also in the science of genetics to _design_ our children!

Whatever lies ahead, it seems obvious that one of the most important things the computer can help us think about is the computer itself. It is a big part of our future.
