The Age of Spiritual Machines: When Computers Exceed Human Intelligence [Anglais] [Broché]

prévisions sur le futur de la race humaine d'ici à 100 ans, très bien argumentées, à lire pour tous ceux qui s'intéressent à notre avenir...

Tout en étant technique sur des sujets parfois difficile c'est avant tout d'une grande clarté et d'une facilité incroyable.
Parfois un peu trop argumenté et donc répétitif il se lit comme un roman et fait beaucoup réfléchir. Les implications sont énormes et font parfois froid dasn le dos. On hésite à en parler car on pourrait passer pour un fou furieux...

It is interesting to read this older book after the more recent ones. It reveals some of the ideological axioms and methodological traits and mistakes that he started from. And unluckily it is necessary to go back to basics at times when you are dealing with a bestselling author in a field where it is easy to predict the future, even the future of the world, the field of technology and what's more information technology.

Ray Kurzweil with more recent books took us into the clouds of his cloud computing and appeared on these clouds like some Messiah who was the rainmaker of the apocalypse, that time when humans will be taken over by another world entirely dominated by a non-human intelligence, even if created originally by man himself. He tries to be the prophet of the future of a world created by evolution stated as intelligent (whose intelligence?) and later by man's intelligence, and then destroyed for plain humans by the machines created by this human intelligence. The vision is a mixture of Terminator 1-2-3-4, Matrix 1-2-3, The Stand, and The Book of Revelation. He even gives at the end of this here book the four Horses of the Apocalypse page 256: Red War ("the species may destroy itself before achieving this step"), White Political Power ("a malfunction," hence a problem in the system whose constitution is not clear cut), the Black Justice or Commerce and their scales ("a software virus" introduced by the badly designed software or by a pirate or hacker) and the Pale Green Pestilence (a "real biological virus" devised and accidentally, on purpose from the machine or on purpose from a malevolent human with reference to the example of "HIV")

But this enormous metaphor, always present in this book, is quite often expressed when speaking of the beginning of the world, the creation of the Universe, the Big Bang, the end of the world, the end of the Universe, the Big Crunch or the Whimper, the beginning of time and the end of time, etc, the total domination with the alpha and the omega, that basic biblical, Jewish, Christian and Islamic concept that time has a first instant and will have a last instant and both were decided by some God. He even manages to present the God's spot of some epileptic god-fearing patients who see God in their trances, and that vision is identified in one spot in their brain in such a way that we may believe it is true for everyman on earth, hence that God is in every single one of our brains.

This is clandestine and yet widely open religious ideology directly borrowed from the basic sacred books of the three Semitic religions. He could have quoted easily the Old Testament, the New Testament, the Qumran Dead Sea Scrolls and the Koran. But he kept his quotations secret. Too bad. When one is speaking religion it is important that this one says so and give the references not to be accused of plagiarism.

Let's start with time. Time does not exist in reality, in the real world. Only duration does and time was invented by human beings as soon as they tried to measure that duration. So it is absurd to speak of an acceleration of time or of a deceleration of time. We may speak of the speed of a phenomenon, but not of the speed of time. Time is a human concept and as such it is absolutely objective and has to remain so, like any measurement invented by human beings. Then he speaks a lot about the subjective impression we have according to various psychological states we may be in. That implies that we feel a certain amount of time as having a short or long duration but duration is not time. A star does not know time, nor duration as for that, but for two different reasons, because time is a human invention and because a star has no consciousness or awareness of duration, or anything else as for that. Kurzweil when speaking of time or using the concept of time is in fact juggling around with colored balls and he wants us to believe he is not a juggler but the balls and their dancing in the air are objective descriptions of the Universe.

If he had been prudent with time he would have been realistic with scientific and technological what's more models. All our knowledge is nothing but a complex set of models built by our mind on the basis of our sensations transformed into perceptions in our brain by our mind.

But Kurzweil never discusses the concept of mind and hardly refers to it. He refers to the brain which would in a way or another contain our intelligence and our knowledge. He uses most of the time a computing metaphor and the brain is a hard disk and intelligence is the software or the programming, knowledge being the memory or the data bank of the hard disk. That metaphor is primitive and it is a shortcut if not a mental short circuit.

What is the mind? The mind is a construct of man's brain built from all the individual has accumulated as for sensations, transformed into perceptions and articulated one on top, or whatever, of the other into a complex architecture from the very first moment of conception. The Pro-life or Pro-abortion debate has no value here. The fetus starts feeling and accumulating things, sensations, as soon as it is a fetus, hence just after conception; That fetus will have a heart of its own around the fourth week and from one beating (its mother's heart) it will shift to two beatings (his mother's and his own hearts) and these two will coordinate from one moment to the next and the fetus experiences from the first day and then from the fourth week the beating of one heart and then of two and the coordination of both. Stress in the mother, pleasure in the mother, fear in the mother change the beating of her heart and the fetus knows it. We mustn't forget that the fetus will eventually develop mirror neurons that will multiply the empathy he is living from the very first day. All that is ignored by Kurzweil.

Worse even he ignores that the child from the twentieth or twenty-fourth week of gestation will be able to clearly hear all that the mother says and all that is said within one yard and a half around the mother, and by the way not only said but all noises or music or whatever sound. Before that audition the fetus could feel the vibrations of the mother's body while she was speaking. Now he can hear the very clusters of sounds she produces, and those are associated to the vibrations, and those that are produced in her direction. At birth the new-born will be able to react to the clusters of sounds that had been common with the mother and experiments were done with the names of the siblings of the new-born and the baby reacted to these clusters one hour after birth. All that is ignored and of course language is ignored in its hierarchical articulated nature.

But there is more. The birth itself is never taken into account and the trauma it brings with discontinuous feeding, with breathing, with hunger and thirst, and the first cry of the baby. It will not take the baby very long to understand that when it cries some adult is going to come to take care of its needs, wants, discomforts and desires. That creates a basic MATRIX of hierarchized functions centering on a relation. The functions are theme and location, source and goal, agent and theme. These functions are the basic functions of any human syntax and the relations, static (of the "be" type or of the "have" type) or active (of the transitive, intransitive, transferring or positioning types, not to speak of the particular transfers of "give" and "take"). All that is learned from experience by the new-born child and built in his mind as a model that will inform the language when words become possible.

Yes the child listens and yes the child will babble and discover that the lip movements of sucking or rejecting the tit of his mother or the bottle-tit can be articulated on the flow of air coming from his larynx and when that larynx starts lowering the child will be able to pronounce "ma", "pa", "da", "ta", "ka". As soon as the larynx is low enough to control the flow of air and as soon as the articulatory power of the mouth, jaws, tongue, glottis becomes more developed the child will be able to produce and articulate more sounds, and he will start associating the clusters of sound with the referential elements around him, on the basis of and into the basic MATRIX he will have by then vastly developed in his mind through and from experience.

But the main mistake of Kurzweil is methodological. He does not seems to understand, actually he can't, that the mind being a construct will change its construction constantly every single time a new element of knowledge appears. That connection between the knowledge and the architecture of the mind is not seen by Kurzweil and the evolutionary nature of that relation is not seen either, especially not in its dual carriageway dialectic: a given state of the mind enables a child to learn a certain item of knowledge but that item of knowledge reacting on the mind changes it and restructures it and then the mind is able to learn some new item of knowledge he could not learn before. And that process is never finished, except with death, that can be mental before being physical, but that's not the point here.

So the main methodological defect appears then.

He states what he calls laws, particularly the Law of Accelerating Returns. But he does not seem to know this law is a mental model constructed by his mind of what might be a natural phenomenon. But his law contains a very old defect generally identified as the paradox of Ulysses and the Hare. If Man's mental development is slower than the machine's development then sooner or later the machine will step beyond man. But he forgets the basic principle of man's development. Lire la suite ›
