The
information technology revolution is different from the preceding technological
revolutions in that it brought about the network in which information in itself
creates information through the continuous feedback loop, whereas all other
technological revolutions were physical. In other words, all preceding
revolutions provided extension of the human body, while IT revolution is
creating extension of the human brain.
Manuel
Castells, a philosopher, authored a thick book “The Rise of the Network
Society” (a first volume of three books), in 1996, to describe the typical phenomena
in “Information Age”. Although Castells wrote this book more than 15 years ago
and some parts seem to be outdated or too familiar to us, we can still learn
from the way he sees the network society.
Network society
Let’s
see the definition of network first. According to him, a network is a set of
interconnected nodes. A node is the point a t which a curve intersects it self.
The
network owes much to the IT revolution and plays central role in the Information
Age. The network society came after the information technology advancement.
Internet is the main stage of this society, in which people interact each other
with unprecedented frequency, creating the vast amount of communication. The
idea of network society is quite common to the people living now, as we usually
use facebook, twitter, etc for our daily communication.
As we
always see, the dominant functions and processes in the Information Age are
increasingly organized around networks. In capitalism society, capital flows
into where the value is created. That means, the capital is invested globally
from and to these networks.
Its impact
The
author argued that the information technology and the rise of network society will
bring about the globalization and change in culture, lifestyles and
enterprises.
Globalization
is exactly what we see now its somewhat brutal process. Culture is made up of
communication process, and if we change the process, it is natural that culture
changes as well. Many are very keen on joblessness especially among the youth,
and some blame technological advancement as the culprit (actually, same thing
happened in the preceding technological revolutions, but in the long run there
will be more job creations to adopt to the change. The point is how to overcome
the turbulence during the transition).
Features of information technology
paradigm
Why
network society matters much to us and why it emerged now? It’s because of the
information technology paradigm. Castells argues that there are five key
features that constitute the heart of the information technology paradigm (from
page 70) :
1.
Information as its raw material. Technologies act on information, not just
information to act on technology. “What characterizes the current technological
revolution is not the centrality of knowledge and information, but the
application of such knowledge and information to knowledge generation and
information processing/communication devices, in a cumulative feedback loop
between innovation and the uses of innovation.”
2.
Pervasiveness of effects. The new technological medium shapes all processes of
our individual and collective existence, because information is the integral
part of human activity.
3.
Networking logic. When networks diffuse, their growth becomes exponential, as
the benefits of being in the network grow exponentially, because of the greater
number of connections, and the cost grows in a liner pattern. According to
Robert Metcalfe (1973), the value of a network (V) increases as the square of
the number of nodes (n) in the net: V = n^(n-1).
4.
Flexibility. As the network is not hierarchically structured, not only
processes are reversible, but also organizations and institutions can be
modified, and even fundamentally altered, by rearranging their components
without destroying the entire structure. What is distinctive to the
configuration of the new technological paradigm is its ability to reconfigure,
a decisive feature in a society characterized by constant change and
organizational fluidity.
5.
Convergence of specific technologies into a highly integrated system. One
element in the technological system cannot exist without the other, and the
borders among specific devices are diminishing. Micro-electronics,
telecommunications, opto-electronics, and computers are all now integrated into
information systems. Some business distinction between chip makers and software
writers will exist for sometime, but not for long.
Remarks
The
five features of information paradigm are still useful to explain what is going
on now and predict what will come next. Especially, the idea of convergence of
specific technologies is informative to me, making me think of the world in
which borders are diminishing. The border is fading out in every field, not
limited to the specific information devices.
