Essay
15. On menage a trois in the Stone Age I made a
noteworthy discovery in the essay by Bill Joy Why the
Future Doesn't Need Us : the words cybernetics
and Norbert Wiener could not be found there by
the FIND function of my MS Word. Cybernetics has
been coming to a postmodern steady state of flow where
newer information and ideas are flushing out the
older ones, very often the same but forgotten,
reinvented, and recombined. The time of my youth was
millennia ago and the fifty year old cybernetics of its
founders became a subject for historians, like alchemy.
I am a
chemist but I have been thinking about cybernetics and
computers for almost half a century. Around 1956,
after the end of the Stalin era, the “bourgeois
pseudo-science of cybernetics” was exonerated, its sins
absolved, and it was allowed to be studied in Russia. I
was among the listeners to the very first lectures on
cybernetics in my native city of Kharkov. The brilliant
lecturer, Yuri Sokolovsky, was a professor of the
local military academy. Soon the
major books of the founders of cybernetics were
published in Russia. As a chemistry student, I attended
the Sokolovsky seminar at my Technical University and
made several presentations myself, including the design
for a reading machine and the mechanism of nervous
impulse. Since then,
I have been watching the developments in the area. I had
my own ideas of a universal thinking machine based on
the scale of sets, did some modest programming, but saw
a computer for the first time only in America. Under the
guidance and with generous help of Ulf Grenander, I got
some working experience with MATLAB. Today
cybernetics for most people means computers but in the
beginning it meant more, and it still means for some
even more than in the beginning, see Principia
Cybernetica site, where
cybernetics is regarded as an aspect of general systems
theory. The terminology has not yet been
established but I would prefer the science of complexity
as the name for the entire area. The reason why
cybernetics is associated with computers is probably
that nothing complex (and often nothing at all) can be
done today without computers. It seems that the initial
meaning of cybernetics has been lost, which is quite
natural, but it was definitely not just about computers.
As far as
definitions are concerned, Norbert Wiener defined
cybernetics as "the science of communication and control
in the animal and the machine". One of the recent
definitions is only slightly expanded: "the science of
communication and control in the animal, machine,
society and in individual human beings." The
machine seems to be out of rank here, but it fits as an
extension of humans. I would specify even further:
"humans and machines made in their image," i.e.,
performing their function of communication and control.
Computer
chips are made of silicon, a chemical element that
constitutes about 28% of the lithosphere, the external
solid layer of the earth. In rocks and sand only oxygen
is more abundant (47%) than silicon. Our
computers, so to speak, still exist in their Stone Age.
They are rock-solid tools made of stone and for this
reason they are sturdy and reliable hardware. They are
in the very beginning of their evolution and, since we
are inseparable from them, they drag us partly back to
our own Stone Age. In 1936 Alan Turing invented an
imaginary (virtual) computer known as the Universal
Turing Machine. Remarkably, any
digital computer that we know today is still
equivalent to it in the sense that both can perform the
same task. Even more remarkably—and that was the core of
Turing's argument—the Turing Machine is roughly
equivalent to a human with a lot of paper, pencil,
eraser, instructions (program), and enough time to
spend. The necessary condition of the equivalence is
that the human who impersonates the machine should
neither think, nor make errors, nor try to do something
on his own, but just follow, with idiotic obstinacy, the
rules and instructions. The rules are simple, but the
instructions can be very complex. On such
harsh conditions, a thinking computer is contradiction
in terms. In order to compute one does not need to
think. Thinking (although not much sophisticated,
either) is needed for programming, i.e., writing
instructions to perform a known procedure. The highest
IQ is still required for inventing a new procedure,
setting a new goal, and formulating the purpose of a new
program, often in plain language, i.e., doing something
for which instructions do not exist. It is hard to
require a sincere and spontaneous human initiative from
a machine. Unless it is so programmed, why should
machine care about humans if it has plenty on its
own machine agenda? The Turing
Machine does not care about time and speed of its work
and it makes no sense to employ it. It is a real Stone
Age technology. We all have developed from the
Stone Age, however, like our bodies developed from a
single cell very much like a primitive bacteria, and our
roots deserve respect. The Stone Age people had all
their magnificent future (i.e., our times, the best of
all) ahead and the Turing Machine, too, heralded a new
era of machine progress toward brilliance. Computer as
we know it is a non-thinking automaton with
inputs, outputs, some modest hardware (the bulky desktop
PC is almost empty), and the program supplied by
thinking humans. Thinking:
what a slippery ground! There are different things, all
called thinking. I have
witnessed the waves of hope and disappointment in
artificial intelligence, fragmentation of the debates on
the nature of mind, the escape from general problems to
highly specialized arcane micro-problems, and, most
recently, its impressive commercialization. I believe that
there had been absolutely no reason to expect computer
(as we know it) to be as intelligent as humans because,
according to Turing (more exactly, the Church-Turing thesis; [the
link is very much worth reading]), computer could
only imitate a very dumb human and vice versa. So much
information has been spewed away on computer printers
about computers that whatever I said could be either
technical or trivial. It seems, however, that we have
not yet exhausted the topic and still do not share a
common understanding of the computer revolution. Concluding
Chapter X of his The Human Use of Human Beings and
recalling Samuel Butler (see Essay 6), Norbert
Wiener noted that "...machine's danger to society
is not from the machine itself but from what man makes
of it ..." It was written long before PC and mass
computerization. I
have some doubts about that. Today I am less seriously
taking warnings about "danger to society," even coming
from Norbert Wiener because it has always been the
favorite tool of all ultra-conservatives,
fundamentalists, and dictators, as well as terrorists.
Society survives any change, updating its spreadsheet of
gain and loss, and evolution cannot be stopped. The
danger threatens only the society as we know it.
The question is what kind of change can we see today and
expect tomorrow? If I say
that I believe that nothing can be compared with
computer in its effect on human evolution, this my
statement will be a good example of cyber-banality. I
see, however, a narrow crack to squeeze in something,
probably, not patently trite. The reason
for the special role of computers, in my opinion, is not
the novelty of computers and the swiftness of their
invasive impact but their hidden antiquity reflected in
the term cybernetics. I see their evolutionary roots
going far back into pre-history. The desktops and
laptops may be new but what they do is something deeply
rooted in human nature. Well, moving in space is even
more deeply rooted in our animal nature. Isn't computer
just a better way to do mental work, as automobile is a
better way to move around at high speed? An analogy
comes to my mind from embryology. When the single cell
of the fertilized egg starts division, hundreds of the
multiplying cells first stay together in a lump similar
to mulberry (it is called morula, from the Latin
for mulberry ) and later arrange in a hollow sphere or
disk called blastula. The sphere caves in, like a
punched tennis ball, and makes a double-walled
cup, gastrula. Between the two layers, ectoderm (outer)
and endoderm (inner) , a third layer, called mesoderm,
develops. In human
embryo, the layers have
the following future: Endoderm will form the
lining of lungs, tongue, tonsils, urethra and
Mesoderm will form the
muscles, bones, lymphatic tissue, spleen,
blood Ectoderm will form the
skin, nails, hair, lens of eye, lining of
the internal and external ear, nose, sinuses,
mouth, anus, tooth enamel, pituitary
gland, mammary glands, and all parts of the nervous
system. The future nervous system soon differentiates
from the ectoderm as neural tube. The evolutionary meaning of this
analogy is that the complexity of an organism or any
complex system develops by unfolding a simple starting
germ, so that the final abundance of components can be
traced back to the simple beginning. Simple
initial components differentiate further by splitting,
adding, inserting, erasing, and moving—functions
strikingly similar to that of the word processor. The
embryo develops like a novel from its sketch, and to the
novel we go. Thomas Mann
(1875-1955) was one of the most complex and
intellectually refined writers of the twentieth century.
I have not studied his life and creative method, but it
seems to me that some of his images come from abstract
science. Thus, in The Confessions of Felix Krull,
Confidence Man (1954) he casually echoes the
Gottfried Wilhelm Leibniz's concept of time. The
time of writing his monumental novel Joseph
and his Brothers (1934-1944) followed and partly
coincided with fast developments in mathematical
logic and I can hear some distant repercussions in the
book. Thomas Mann
takes the ready germ of the story of Joseph from Genesis
and unfolds it into a long multi-volume novel of
somewhat overbearing complexity by essentially inserting
imaginary episodes and characters between the expanded
traditional ones, similarly to embryogenesis, so that
the parts of the novel can be traced back to the
original account. Thus, a
long, intricate, and loquacious part develops from the
following terse account : Then
there passed by Midianites merchantmen: and they drew
and lifted up Joseph out of the pit, and sold Joseph to
the Ismaelites for twenty pieces of silver: and they
brought Joseph into Egypt. (Genesis,
37: 28)
The backtracking of computer to the
abacus is shallow if taken literally: there is
nothing in the computer from beads and wires. But computer
definitely originates from the procedure of counting, and
this is why abacus is listed as its ancestor. Counting, in
turn, is part of trade and from this ancient aspect of
human existence computing germinates. Control, however,
comes from even much older one, shared by humans with
other social animals ruled by the alpha male, not to
mention the central nervous system. Operations
with symbols require incomparably less energy than
operations with matter. Control, the central subject of
cybernetics, has always been an art of producing big
consequences by small causes and giving orders in a
quiet voice, even whisper or gesture—in business,
politics, or on the battlefield. Inanimate
physical nature has no idea what symbol is and, for that
matter, has no ideas at all. It deals with direct
interactions, mostly between two objects. Nature is
honest and straightforward, or, as Albert Einstein put
it, God is subtle but not malicious. If so, life with
its chase, fight, mating, hiding, bluff, and mimicry is
godless. Cybernetics deals with a triplet: input, output, and control. Its elementary structure is T-shaped: information flowing from A to B (or back) is controlled (modified, processed, modulated, switched) by C. This ménage à trois seems to me the central idea of cybernetics, and control can be both subtle and malicious. In the novel
about Joseph, in the chapter compellingly entitled
Threefold Exchange, Thomas Mann describes a
subtle and malicious trick that Joseph's enemy Dudu
plays on both Joseph and Mut-em-enet, Potiphar's wife,
in order to bring them together for the sake of Joseph's
peril. Iago achieves a similar effect with Othello and
Desdemona by splitting them apart. Both Dudu and Iago
control the interaction between the couples. A chemist
controls the honest interaction between the components
by varying temperature and catalyst. A villain controls
the interaction by disinformation. It seems
like a rare coincidence that the same term cybernetics,
with essentially the same meaning, was independently
invented in 1838 by André Marie
Ampère and in
1948 by Norbert Wiener. To me it confirms that
cybernetics is a very ancient subject comprising various
situations with the external interference in information
processing: government, steering, driving, politics,
media, management, and communication, all of them
including manipulation of the "natural" or "direct"
course of things. Cybernetics, in other words, is about
the non-physical world. Or, if you wish, it is an extra
chapter of physics which is necessary for applying
physics to life, intelligence, and society—systems of
high complexity irreducible to equations. The brain,
helmsman, driver, and governor—functions that contribute
to the semantics of the term cybernetics CubernhthV
(kybernetes:
navigator, steersman, governor)—cannot leave
the body, ship, vehicle, and nation (actually, Wiener
meant the flyball
governor of the steam
engine) to negotiate with external forces on their own.
They try to outsmart the laws of physical,
biological, and human nature in order to survive
and win. This is a truly primary layer of the embryo of
civilization. I would not characterize it as
mesoderm, however. The brain and nervous system
grow between the organism and the world, from the
ectoderm, i.e., from the interface between the organism
and the world. The brain is
the controlling C of the figure. It mediates the inputs
A and outputs B in a "threefold exchange." It
warps the direct and honest interaction between the
world and the organism, which would, most probably, kill
the organism. It makes behavior deceitful and
cunning but less deadly. Brain arbitrates a deal between
the individual and environment, spreading the time scale
of the deal beyond the present moment. The flyball
governor of the steam engine maintains the speed
constant by manipulating the steam pressure. The
governor of the state navigates through the variations
of the political pressure. In the
embryological key, people started doing some computing
in the form of transportation. Kill a deer in the woods and bring
it home for cooking.
NOTE. Ka was
different from Ba, soul, which could freely roam
the earth. The subject, however, is much
more complex and my use of the terms is rather
arbitrary. The Turing
Machine can be implemented by a large warehouse where
computation is done by placing (corresponds to writing)
or removing (corresponds to erasing) copies of two
objects (corresponding to 0 and 1) , on and from the
shelving, according to a book of instructions. Transportation
of inanimate things was the very beginning of
computation. Unlike computer programming, transportation
has to deal with:
large objects The use of
the abacus cut down on the extent of all four components
and reduced handling the Ka of the objects to
moving the beads back and forth. Like symbols
in the computers made of stone, or like the beads in the
abacus, the Things cannot spontaneously change their
place, appear out of nothing or disappear, unless they
are alive. Computation
deals with two things: 0 and 1. While the airplane
transports passengers and their bags, burning a lot of
fuel, the airline computer transports zeros and ones
(the stuff of their Ka) from one place to another
within itself and with a minuscule energy spent for each
transportation. The computing in an airline
computer has the actual transportation as result. Now a
suitcase has a double existence: as suitcase and as an
entry in a computer, like the goods of the Midianite
merchant in Joseph's inventory, and so are the jet
liner, the passenger, and even France. What is the
difference, then, between Joseph's calculations, abacus,
modern card size calculator, and computer? Why is it not
enough to see computers as mere tools, definitely less
harmful than cars and airplanes? Why not to regard
computers as just extensions of our brain, like pliers,
hammer, and screwdriver are extensions of our hands? The physical
interactions are direct and "honest" in the Einstein's
sense. In the physical contact between the tool and the
object, say, hammer (A) and nail (B), there is no C in
the cybernetic triplet. This is
still true for the work of a programmer: there is
nothing between the young computer geek and the
computer. This is why programming can became an
obsession, like gambling, and I would like to make a
short digression on that. It is not too often that young
people are drawn to science and technology. The early
interest in complex subjects is not typical, while
interest in sports and entertainment is.
Programming
and games, however, are not the only way to spend time
with computer. In the
social system (I include technology and environment in
social system), the computers
become a new organ or, rather, tissue, omnipresent
like blood vessels and muscles in a living organism.
Unlike telephone that does not process information,
computers wedge in between C, A, and B and
create an additional interface: human-human,
Thing-Thing, and human-Thing, so that the direct
interaction becomes less typical than the indirect
one. The
world has to filter through computers before it reaches
a mind, natural or artificial, and the mind is separated
from the outputs in the same way. I
am sure that a determined researcher can show how word
processor changes the style of literature as compared
with the quill and the typewriter. The
simplest and highly typical example of the new situation
is the email filter that we use to guard off the spam.
There are filters for much more sophisticated control,
for example, SuperScout ,
with artificial intelligence capabilities that promise
to prevent sexual harassment, protect company image, and
much more. The document processing software, such
as Autonomy ,
takes care of internal information. It promises to
understand emails, voice, text, documents, web pages,
people ("profiling users basing on the ideas in the text
they read or write") and, in general, as its motto says,
"read between the lines". See also Cycorp. Autonomy
Corporation,
as I can conclude from advertisement, makes a
probabilistic software that is never error-free and it
honestly states so. I somewhat misanthropically believe
that it will compete very well with average employee
performing the same functions, especially, in the
government. Nevertheless, it is yet another step in the
growing development of "interfacial society" that
started with multiple choice answering systems at banks,
telephone and other companies, and the government,
mostly very useful and efficient, and only occasionally
frustrating. With
software like Autonomy, computers can soon become not
only the generators of mammoth government documents like
the national budget or an independent counsel report,
but also their sole in-full readers. The Smart
Tags of Windows XP that give filtered information on
words in the text is the most recent example of
the control over control and the oncoming takeover of
control by computers, in this case, in the name of the
Microsoft's well-being. This
is the normal process of evolution from simple forms
toward complexity that we can observe on biological
evolution (recapitulated on high speed in
embryogenesis), history, and creative writing. How
long can complexification last and whether it can be
reversed is an intriguing question. but not for
this Essay. I believe that the substitution of answering
system for a human bank clerk is already such a
simplification. This, however, calls for the
specter of Bill Joy's Why the
Future Doesn't Need Us . But first, multiculturalism
has to embrace the culture of Things and autonomous
cybernetic systems, which may take longer than the
lifespan of multiculturalism. Here we come
to the core of the new situation. The tools,
from the screwdriver to the railway train, are Things.
Computer is a Thing, too, but not just a Thing. The
Things attach the humans to the cycles of their
business metabolism, and so does computer as hardware.
Software as Thing is a different matter. The new
evolutionary turn brought about by computers is that
computers make commercialization ( i.e. turning into
Thing for sale) of control not simply possible (as
happens with humans in case of corrupt officials) but
typical and independent of the intent of human users.
Computers control the communication and the control
itself not because people use them in an inappropriate
or dangerous, as Norbert Wiener anticipated, way but
because they are mass-made and universally spread as an
interface, a new social tissue, and because they are
themselves Things, i.e., a form of life (life form). Operons,
i.e., the three-point units of control (from switches to
brains), form a triumvirate with gene and meme (see Essay
6) in the super-system developing right
before our eyes where genes, memes, and operons are
Things for sale. Things for sale propagate their
blueprint memes like oak propagates its genes
through the acorns. If computer
were simply a counting, computing device, a
super-abacus, there would be as little problem
with the new tool as with a better mousetrap. A new tool cannot
radically change our lives. But a new organ, a whole new
biochemistry and physiology, a new source of
energy, levitation, teleportation, and a new principle
of social organization would mean a radical
evolutionary step. Computer is
not just a computing tool but a cybernetic, i.e.,
controlling device with its software made outside, in
the business cycle. It is a kind of a social
formation, function, organ, or tissue, in short,
subsystem. This double identity of the computer, in my
opinion, comes from the evolutionary difference between
the functions of computation and control. Computer
that computes a function is a computing device. Computer
that decides the fate of an email, employee, or idea is
a control device that deeply interferes with the
evolutionary fate of components of a complex system. We
cannot blame humans for using computers anymore because
"the railways ride the people." (see Essay 6). Rights come
with responsibilities. To make a piece of software a
Thing for sale was a sharp revolutionary rather than
evolutionary turn toward the society without
responsibilities and we are going to face the
consequences in the sphere of rights. It is most
extraordinary that the new turn has been accomplished
with the computers of the Stone Age. Our brain
cells consist mostly of water with addition of fat and
proteins. It remains to be seen whether we need to
manufacture chips from mayonnaise in order to make it to
the next stage where computation is achieved by
trial and error, learning, invention, and inspiration. It is easy
to imagine a computer that we do not yet know:
It not only makes errors—this is the easiest part of
being human—but tries various approaches, fails, wins,
disobeys instructions, changes them, and evolves. In
other words, it is an equivalent of a human of
high IQ and independent character. As Thomas
Mann noted, "Part of the game we play with life consists
in relations of human beings one to another." For
better or worse, no more: it is going to be ménage à
trois.
