Predictions on our computerized future. Clive Sinclair.

Four thousand million years ago, when the universe was only half the size it is now and the solar system only five million years old, a singular thing happened--life. By some ineluctable process in the primordial soup, stirred by fierce cosmic rays and bolts of lightning, carbon compounds of strange complexity formed and reformed, growing in subtlety until they came to transmute sunlight and to replicate. For a billion years these first bacteria, so mysteriously conjured, clumping together to form living reefs called stromatolites, where the only life. Yet three billion years later they evolved into mankind.

I said that the event that started this process was singular and so, for all we know, it was. But so it will not long remain. All life is carbon based and carbon is exceptional in the variety of compounds it leads to, providing organisms with a rich choice of building materials. If we ever discover life on other planets we would not be surprised to find it similarly based on carbon, but it might not be so.

When I was a boy I read science fiction stories and in those days a common theme was the discovery of a life form strangely different from ours. A popular idea was for life based not on carbon compounds but on silicon on the grounds, I believe, that silicon too can form a wealth of products, many of them physically useful. Soon, I suggest, those stories will seem strangely prescient, for silicon based life will exist. IT will not have emerged from millions of years of trial and error in energetic protoplasm but from a mere century or less of man's endeavour I am suggesting that the path the silicon based electronics industry is on will lead to life.

The human brain contains, I am told, 10 thousand million cells, and each of these may have a thousand connections. Such enormous numbers used to daunt us and cause us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such as pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can, we will. It may then take us a long time to render it intelligent by loading in the right software or by altering the architecture, but that too will happen.

It think it certain that in decades, not centuries, machines of silicon will arise first to rival and then surpass their human progenitors. Once they surpass us they will be capable of their own design. In a real sense they will be reproductive. Silicon will have ended the long monopoly of carbon. And ours too, I suppose, for we will no longer be able to deem ourselves the finest intelligence in the knwon universe. In principle, it could be stopped. There will be those who try, but it will happen nonetheless. The lid of Pandora's box is starting to open. A Look at the Present

But let us look a little closer to the present.

By the end of this decade, manufacturing decline will be nearly complete--with employment in manufacturing industries less than 10% in Britain. The goods are still needed, but, as with agriculture already, imports and technical change will virtually remove all employment.

Talk of information technology may be misleading. It is true that one of the features of the coming years is a dramatic fall, perhaps by a factor of 100, in the cost of publishing as video-disc and other technologies replace paper. This may be as significant as the invention of the written word and Caxton's introduction of movable type. But talk of inofrmation technology confuses an issue; it is used to mean people handling information rather than handling machines, and there is little that is fundamental in this.

The real revolution, which is just starting, is one of intelligence. Electronics is replacing man's mind, just as steam replaced man's muscle. But the replacement of the intelligence employed on the production line is only the start. The Japanese, with their ICOT program, are aiming to make computers that will deal with concepts rather than numbers. this has triggered a swift and powerful response in the American nation. There is a large joint program of development amongst leading U.S. computer companies. There is at least as large a DARPA program, and IBM, though it says nothing, may well have the biggest program of all. Looking Ahead to the Fifth Generation

These projects ar aimed at what are loosely termed fifth generation computers. These are really a new breed of machine entirely and will be as different from today's computers as today's computers are from adding machines.

Powerful as these new engines will be, they will not remain inordinately expensive thanks to progress in the semiconductor industry. Onec available, they will start to replace human intelligence at ever higher levels of abstraction.

The simple microprocessor provides sufficient intelligence for current assembly line robots. As robots learn to see and feel, their brains will grow. Eventually, and not too far in the future, they will make decisions on the production line currently delegated to supervisors.

Outside the factory, we employ men's minds in two principal ways: as fonts of knowledge and as makers of decisions. The former of these attributes is now falling prey to the machine with the development of "expert systems" whereby the acquired knowledge of a man, an expert in mining for example, is made to repose in the memory of a computer. The transfer of data from human to machine mind his neither easy nor swift, but once attained it may be copied at will and broadcast. A formerly scarce resource can thus become plentiful.

The ability to reach wise conclusions, as we expect of a doctor or lawyer, from much or scant data will longer remain man's monopoly but not forever.

Fifth generation computers will share this prerogative. Tomorrow we may take our ailments to a machine as readily as to man. In time that machine will be in the house, removing the need to journey to the doctor and providing far more monitoring of the state hof health than it is now economic to provide.

The computer as surrogate teacher may bring even more benefits. Today, and as long as we depend on humans, we must have one teacher to many pupils. The advantage of a tutor for each child is clear, and if that tutor is also endlessly patient and superhumanly well-informed we may expect a wonderful improvement in the standard of education. What, though, is the purpose if, in this imagined future, there are no jobs?

Curiously, we can find analogies in the past. Freemen of Periclean Athens led not such different lives as we might live, for where we will have the machines, they had slaves who served both teachers and as menials. Thanks, perhaps, to their fine education, the freemen of Athens seem not to have found difficulty i filling their time. Just as they did, we will need to educate our children to an appreciation of the finer things of life, to inculcate a love of art, music, and science. So we may experience an age as golden as that of Greece. Other Amazing Machines

Machines will be capable of replacing men in tasks requiring complex motor functions. Strangely, I think it many be easier to make a machine to teach mathematics or Latin than to make one to play tennis for the latter task calls for an astonishingly fine and rapid prediction and decision coupled to precise action.

But still it can and will be done. Not to relieve us of hte pleasure of playing games but to relieve us of the monotony and danger of nearly as complex a task, that of driving a car. We took to cars for the freedom they conferred to travel from any one place to another at any time, secure from the elements. We have paid quite a price in the mortality of our peoples and the pollution of our lands. We have chosen to restrain these remarkable vehicles to much less than half the speeds they could readily attain to mitigate these two evils.

The future promises a better solution. I anticipate totally automatic personal vehjicles still with all the freedom in space and time of today's cars, but guided by machine intelligence. They will be powered by electricity drawn from internal batteries in towns and on minor roads and on the highways from a main supply possibly inductively coupled into the vehicle.

These latter day cars will be well nigh silent and clean but, above all, free from human fallibility. They need not then be restricted to 55 or 70 mph on main roads. Speeds of over 200 mph should be safely and economically possible. Magnetic levitation might replace wheels with advantages in the quality of ride, in silence, and in the longevity of the vehicle which, having no moving parts would need no regular servicing. It is entirely possible that the performance of these vehicles will become such as to obsolete aircraft for all but the longest journeys and those over water.

The linking of the telephone to ever more sophisticated computing machinery is leading to major improvements in the service available. The latest of these is the cellular radio system of communication now growing in some American cities. I see this as a partial solution to the general problem of permitting people to telephone one another no matter when or where. It is but temporary economic restraint not technical fundament which bars us from the logical conclusion of truly personal telephones. Carried on or about the person, these wireless devices would allow us to telephone and be telephone wherever we choose.

I would not need to know the whereabouts of the person I was calling, only his number, since this would be particular to him wherever he was instead of to a fixed instrument as is usual now. I believe this is achievable by an extension of the cellular principle in area and capacity, the latter requiring much finer granularity in the system. That is to say, the controlling transceivers will need to be far more closely spaced.

It often seems that each new step in technology brings misery rather than contentment, but this is because it brings change faster than benefits--and change, though often stimulating, is always disturbing. So it is and will be with the intelligence revolution, but here the benefits to come handsomely outweigh the trauma. Even our most intractable problems may prove soluble.

Consider for example the imprisonment of offenders. Unless conducted with a biblical sense of retribution this procedure attempts to reduce crime by deterrence and containment. It is though, very expensive and the rate of recidivism lends little support to its curative properties.

Given a national telephone/computer net such as I have briefly described, an alternative appears. Less than physically dangerous criminals could be fitted with tiny transporters so that their whereabouts, to a high degree of precision, could be constantly monitored and recorded. Should this raise fears of an Orwellian society, we could offer miscreants the alternative of imprisonment. I am confident of the general preference.

Intelligent robots will also help to care for the elderly who might even find companionship. Sleeplessly vigilant, the robot could provide for normal physical needs and watch for medical problems.

As the intelligence of robots increases to emulate that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on earth through their ability to withstand environments inimical to ourselves. Thus, deserts may bloom, and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, we can really begin to use space to our advantage. The construction of a vast, man-created world in space, home to thousands or millions of people, will be within our power and, should we so choose, we may begin in earnest the search for worlds beyond our solar system and the colonization of the galaxy.
