EXECUTIVE SUMMARY
|
|
|
|
SRI International Futurist Tom Mandel describes the history, rapid growth,
|
|
and
|
|
varied interactions on internetworked computer systems such as the Internet.
|
|
Developed from research-related university and government communications
|
|
systems, the Internet is now doubling in size each year. The entire global
|
|
electronic information matrix, which includes the Internet, will probably
|
|
reach
|
|
more than 500 million users by the end of this century. As a significant part
|
|
of the infrastructure for the emerging information society, the Internet
|
|
reveals the major new issues created by a world where copyright replaces
|
|
property right, theft becomes invasion of privacy, and the realities of
|
|
social
|
|
interactions include on-line personas, information addiction, virtual coffee
|
|
houses, and lovers who tryst without ever meeting through the exchange of
|
|
e-mail and sexually explicit graphics files. In this electronic community, a
|
|
"new frontier" ethic among collaborative users motivates continuing user
|
|
innovation in communications software, information filters, and encryption
|
|
programs. The first truly wide-membership global community, the Internet has
|
|
created and will continue to innovate new versions of work and play, love and
|
|
crime in human society. The major future uncertainty concerns the evolving
|
|
boundaries of this network, the network's ultimate penetration into corporate
|
|
and personal spaces, and the dynamic effects of increasing interconnectivity
|
|
on
|
|
economies, nations, and values.
|
|
|
|
SURFING THE WILD INTERNET
|
|
|
|
Computerized communications networks such as the Internet create the
|
|
technical
|
|
foundation of the information society. Its rapid growth and varied
|
|
interactions
|
|
define the norms and aspirations of this new world.
|
|
|
|
One forecast that has proved true about the information society is the rapid
|
|
emergence of computer/communications networks. Throughout the late 1980s and
|
|
into the present, no corners of the information infrastructure exist where
|
|
connectivity (linked computers and communications systems) and
|
|
internetworking
|
|
(networks of computer networks) are not growing explosively. The business,
|
|
social, and political consequences of increasingly dense connectivity will be
|
|
far reaching, and the patterns of change are visible in the activities
|
|
already
|
|
going on.
|
|
|
|
Outside the public switched telephone network-the global computerized
|
|
telephone
|
|
systems-the Internet is the world's largest computer internetwork. It
|
|
developed
|
|
in the early 1980s, as a restructuring of the U.S. Department of
|
|
Defense-funded
|
|
ARPANET computer network, to connect several hundred university and U.S.
|
|
government mainframe computers (hosts) for the exchange of electronic mail
|
|
(e-mail), information, and computing resources. Since 1986, the number of
|
|
computer hosts on the Internet has grown at approximately 100% per year, and
|
|
by
|
|
January 1993, the Internet connected more than 1 300 000 hosts in nearly all
|
|
major countries (see Figure 1). No one knows how many people access Internet
|
|
computer services, but estimates range from 8 million to 15 million people
|
|
worldwide-and these estimates exclude users on hosts that, for security
|
|
reasons, are invisible on the Internet system. Although growth of the
|
|
Internet
|
|
in the United States is slowing down (to 80% in the past year), growth
|
|
elsewhere in the world is just starting to take off. For example, the number
|
|
of
|
|
hosts increased 200% in the United Kingdom last year (where Internet hosts
|
|
now
|
|
number more than 58 000) and increased some 170% in Japan, with nearly 24 000
|
|
hosts (see Items Worth Noting in the February Scan).
|
|
|
|

|
|
growth of Internet hosts from about 200 in 1981 to roughly 1.3 million
|
|
as of January, 1993. Source: SRI International.]
|
|
|
|
Growing alongside the Internet are the tens of millions of users of a number
|
|
of
|
|
packet data networks such as Sprintnet, BT (British Telecom) Tymnet, and
|
|
Compuserve Packet Network and the tens of thousands of companies worldwide
|
|
that
|
|
link employees with private local- and wide-area networks-many of which
|
|
connect
|
|
to an internetwork. According to John Quarterman, publisher of Matrix News,
|
|
these corporate computer networks are together already at least as large as
|
|
the
|
|
Internet itself. Cellular radio networks such as Viking Express and Ardis now
|
|
provide interconnectivity to notebook computer users, and-in the near
|
|
future-telephone systems will offer digital information services that will
|
|
effectively make them large internetworks as well. New internetworking
|
|
standards that have rapidly evolved during the past five years ensure that
|
|
the
|
|
complexity and connectivity of these different networks and internetworks
|
|
will
|
|
increase by several orders of magnitude in the 1990s. At the end of this
|
|
decade, internetworks will link several hundred million computers together,
|
|
and
|
|
the total number of users with access to the global electronic information
|
|
matrix will exceed 500 million.
|
|
|
|
More interesting than the sheer volume of communications are the mostly
|
|
unpredicted new behavior and social phenomena that the internetworks nurture.
|
|
An overview of the major developments hints strongly at both the bright and
|
|
the
|
|
dark aspects of the emerging information society.
|
|
|
|
People's Need to Talk
|
|
|
|
One of the most rapidly growing categories of exchanged files on the Internet
|
|
is personal communications. Today e-mail and facsimile mail are the two most
|
|
rapidly growing new media for direct connection between individuals,
|
|
businesses, and other organizations. Experimental network connections for
|
|
e-mail between politicians and the public have existed for many years,
|
|
started
|
|
by telecommunications visionaries such as Dave Hughes in Colorado, but now
|
|
these experiments are spreading rapidly. During the 1992 election campaign,
|
|
President Clinton's campaign staff publicized an e-mail address through which
|
|
the public could ask questions, express opinions, and provide or receive
|
|
information. Compuserve still maintains an e-mail connection to Clinton's
|
|
staff, and reports suggest that members of Congress will soon be addressable
|
|
via Internet e-mail. Because these channels can support the same
|
|
question-and-answer format that President Clinton has popularized through
|
|
televised town-hall meetings, internetworking will likely accelerate the
|
|
change
|
|
in the power relations of public political dialog. Prodigy, the largest (in
|
|
number of users) U.S. interactive consumer information service, recently
|
|
announced that it would offer e-mail services to and from the Internet.
|
|
Because e-mail addresses are usually on password-secure personal computers,
|
|
e-mail can exceed the postal service as a private, secure communications
|
|
channel. As a result, even love and sex occur through electronic messages.
|
|
Some
|
|
users get to know each other in newsgroups (see below) and Internet Relay
|
|
Channel (IRC), start flirting, and carry on long-distance electronic
|
|
relationships without ever meeting. Occasionally one even runs into the
|
|
network
|
|
equivalent of obscene phone calls. And some user groups create text and
|
|
digital
|
|
graphic files of erotica, then swap these files electronically with other
|
|
Internet users. These examples are also the first public efforts to use the
|
|
Internet for primitive multimedia communications.
|
|
|
|
Real-time conferencing channels are much smaller than e-mail services, which
|
|
can exchange mail with almost all major private and public networks through
|
|
the
|
|
Internet. The first computer businesses to offer real-time computer
|
|
conferencing services quickly discovered that their customers liked to banter
|
|
in real time about life-style and personal interests. The Internet developed
|
|
"chat" features as a result. One of these features-IRC-provides real-time
|
|
communications to thousands of users worldwide at hundreds of different
|
|
sites.
|
|
IRC's structure has different "channels," not unlike conference telephone
|
|
calls, that may address any topic, from research to postadolescent prattle.
|
|
Some channels are completely private. Most, but not all, IRC participants are
|
|
college students using university Internet hosts around the world. Within an
|
|
IRC channel, it is not unusual to banter simultaneously with users in Taiwan,
|
|
Korea, Finland, Switzerland, Israel, Australia, Canada, and the United
|
|
States.
|
|
Time-zone differences matter little to the night-owl habitues of the IRC
|
|
"virtual cafe." And English is the language making global chat possible (much
|
|
as English created a global rock music culture). Other, better-designed
|
|
real-time conferencing systems, such as Scott Chasin's 4m (for forum), are
|
|
emerging to meet the growing demand for conferencing that is less chaotic and
|
|
spirited than often prevails in IRC.
|
|
|
|
Global Computer Conferencing
|
|
|
|
When the ARPANET started, a number of users developed programs so that they
|
|
could discuss subjects of interest to them in text versions of round-table
|
|
discussions. A system of "newsgroups" and later "mailgroups" emerged that
|
|
users
|
|
can enter through the Internet, USENET (a network of Unix and other systems),
|
|
BITNET (a network of college systems), and other networks. Users "subscribe"
|
|
to
|
|
the newsgroups of their choice, which are available to their host computer
|
|
systems; they read and respond to text messages within directories that
|
|
define
|
|
specific topics of interest. The more private mailgroups go to individual
|
|
subscribers rather than hosts, and membership in some (such as mailgroups
|
|
discussing computer security) is restricted to qualified people. Early
|
|
newsgroups focused on computer use-an early group addressing "computer risks"
|
|
still thrives today-and science fiction. By the mid-1980s, just before the
|
|
Internet started growing rapidly, perhaps 300 different newsgroups were
|
|
available over thousands of computer systems. Today, more than 3000 such
|
|
newsgroups are available to more than 1 million hosts and perhaps ten times
|
|
as
|
|
many individual users. The public electronic file listing all known
|
|
mailgroups
|
|
is some 300 printed pages long. Though many newsgroups are technical, the
|
|
most
|
|
active address social, political, recreational, and other special interests.
|
|
The technical information frontiers have rapidly transformed into habitats
|
|
for
|
|
personal and everyday use, and on a global scale.
|
|
|
|
Freedom of Information
|
|
|
|
The Internet is awash with information, both useful and banal. In a very real
|
|
sense, the entire Internet (and other internetworks) is becoming one
|
|
extremely
|
|
large, globally distributed, and mostly public electronic library, post
|
|
office,
|
|
and discussion forum. The Internet evolved with a strong and explicit
|
|
philosophy of sharing information (mail, documents, programs, data, and
|
|
graphics), and that perspective has dominated how the system works today. The
|
|
internetwork has evolved into a web of public and private channels bounded by
|
|
explicit security barriers. Occasional network horror stories-such as the
|
|
1989
|
|
computer "worm" originated by a Cornell University graduate student, which
|
|
incapacitated hundreds of public and private computers on the Internet
|
|
system-have actually improved the overall reliability and security of
|
|
internetworking. In this context, a distinctive new-frontier ethos has
|
|
developed among Internet users, championing the free exchange of information
|
|
and the intricate new issues of on-line etiquette, expression, and user
|
|
protections against vandalism, harassment, invasions of privacy, and
|
|
commercial
|
|
solicitations. These users' credo is "Information wants to be free."
|
|
|
|
Texts from the Internet Library
|
|
|
|
The originating purpose of the Internet was the exchange of computer files,
|
|
and
|
|
this exchange remains a primary activity on the network. A basic Internet
|
|
tool
|
|
is FTP, a program that enables users to move files from one Internet computer
|
|
to another. Some large corporate and university systems maintain large public
|
|
FTP directories-"anonymous FTP sites"-listing all the files available to
|
|
public
|
|
access. But as the Internet grows, simply finding where programs are located
|
|
becomes increasingly difficult, so easy-to-use search tools make this task
|
|
easier. Archie, one of the most widely used programs, can locate the more
|
|
than
|
|
2.1 million computer programs in the Internet public FTP directories,
|
|
according
|
|
to Ed Krol, author of The Whole Internet User's Guide and Catalog. An Archie
|
|
search is usually straightforward and simple; it can take as little as a
|
|
minute
|
|
to identify specific programs worldwide that are publicly available via FTP.
|
|
Archie is relatively crude compared to newer programs to search for
|
|
information
|
|
on the Internet. Gopher burrows through indexes of files; presents the
|
|
contents
|
|
much like a multiwindow, interactive card catalog in a library does; and lets
|
|
the user browse the contents of selected documents. Different Gopher servers
|
|
provide access to different kinds of information on different parts of the
|
|
Internet-from UPI press feeds as an indexed resource to entire libraries of
|
|
books. WAIS (Wide Area Information Service) is a newer and more sophisticated
|
|
Internet information searching program (see D92-1612, Wide-Area Information
|
|
Servers: An Executive Information System for Unstructured Files). WAIS lets
|
|
users ask simple questions, essentially searching WAIS-directoried files
|
|
available on the Internet for particular words and phrases, and refining
|
|
keywords until they locate desired files. Some 250 WAIS libraries are
|
|
currently
|
|
available free on the Internet, maintained by volunteer effort and donated
|
|
computer time. Commercial services such as Dow Jones Information Service also
|
|
use the WAIS interface to provide searchable information on a for-fee basis.
|
|
|
|
Computer Fun and Games
|
|
|
|
Internet users were quick to use internetworking for recreation. Whole Earth
|
|
Catalog founder Stewart Brand (in "Fanatic Life and Symbolic Death Among the
|
|
Computer Bums," Rolling Stone, December 1972) first described the tendency of
|
|
mainframe-computer programmers to create and play new computer games for
|
|
hours
|
|
on end. This phenomenon is repeating on the Internet but with a new twist:
|
|
During the past several years, several hundred interactive, multiuser
|
|
simulation games (or environments)-MUDs and MUSEs-have popped up on Internet
|
|
hosts. MUD stands for Multiuser Dungeons and Dragons and MUSE, which is more
|
|
generic, means Multiuser Simulation Environment: computer versions of board
|
|
adventure games. Several hundred MUDs and MUSEs are now running on mostly
|
|
university-based Internet systems, and many are accessible from elsewhere on
|
|
the network. MUSE users take advantage of special computer languages to
|
|
create
|
|
in-text fantasy environments that can interact with each other as if their
|
|
individual MUSE were a real world. Most MUSEs are wild, chaotic science
|
|
fiction
|
|
or fantasy worlds, but some are very serious experiments. Cyberion City, a
|
|
MUSE
|
|
that "lives" at the Massachusetts Institute of Technology (MIT) in Cambridge,
|
|
Massachusetts, is a multilevel "spaceship" being designed, built, and
|
|
constantly modified by elementary, high school, and college students (and a
|
|
few
|
|
adults). Several computer research companies are exploring the MUSE medium,
|
|
and
|
|
at least one graphical MUSE interface is under development in Europe. Many of
|
|
these simulations are available on the Internet.
|
|
|
|
Semi-Intelligent Bots
|
|
|
|
Finally, semismart software programs-bots (for robots) are appearing in
|
|
certain
|
|
parts of the Internet. These programs reside in various applications and
|
|
perform tasks tailored to an individual user's needs. Some IRC users program
|
|
bots to record conversation, note the arrival of and send messages to special
|
|
friends, and provide information on request to other users. In the MUSE
|
|
world,
|
|
bots can be programmed with distinct personalities; in Cyberion City, the
|
|
fashion is to create a personal bot that will greet visitors to the user's
|
|
simulated world when the creator is not logged on. Bots represent the first
|
|
user-programmed steps toward true network agents-programs that will perform
|
|
specific services for individual users anywhere on the network.
|
|
|
|
Besides performing these explicit communications functions, the Internet is
|
|
effectively an experimental social system, inhabited by computer-literate
|
|
people and shaped by the infrastructures, standards, protocols, expertise,
|
|
and
|
|
values that enable communications through the internetwork system. The major
|
|
implications of this new system emerge from the patterns of interaction
|
|
already
|
|
visible within it:
|
|
|
|
o
|
|
An information community. Internetworkers share only information, and this
|
|
focus profoundly redefines the basic issues of human community. Copyright
|
|
replaces property right, computer security replaces home security, file
|
|
erasure
|
|
replaces arson, freedom from harassment replaces invasion of privacy. The
|
|
materialistic, racial, gender, and occupational stratification of society is
|
|
superseded on the Internet by a new class structure based on expertise,
|
|
connectivity, access, and "on-line persona." This change redefines the power
|
|
and privacy assumptions that developed around other communications: The
|
|
techniques of mass-media advertising and personal solicitation are widely
|
|
scorned by the internetworking population. Politics, work, and recreation are
|
|
undergoing redefinition as well.
|
|
|
|
o Information junkies, information overload, and hypersegmentation of
|
|
interest.
|
|
The new information world has revealed human psychological tendencies and
|
|
limitations unknown a decade before and is penetrating and opening individual
|
|
lives in unexpected ways. Curiosity and facility with network tools are
|
|
creating a growing number of people extremely adept at gathering information
|
|
off the Internet and connected systems. Some of them have become information
|
|
junkies, avidly collecting trivia just for the sake of the search. Addiction
|
|
to
|
|
network personal communications and discussion groups is a problem for
|
|
others.
|
|
The Internet defines new kinds of addiction, abuse, and "cyberpathological
|
|
behavior." Users less avid for information sometimes complain of information
|
|
overload-a rare complaint just a few years ago but one that is common today.
|
|
One result is that new kinds of message-handling and filtering programs are
|
|
emerging, creating personal windows of interest through which unwanted
|
|
information may not pass. Individual "bozofilters" allow newsgroup users to
|
|
avoid seeing postings by irritating cosubscribers, and "killfile" commands
|
|
let
|
|
wire-service subscribers exclude news on particular topics. With 3500
|
|
newsgroups and a third as many mailgroups, users must focus quickly on what
|
|
matters most, creating a hypersegmentation of interest areas. Specific
|
|
newsgroups exist on a broad range of social, legal, and business issues (in
|
|
the
|
|
United States, Germany, Australia, and other countries); on software; on
|
|
computer hardware; and on nearly every sport and hobby imaginable. These
|
|
tools
|
|
will accelerate a trend toward narrow but intensive information and
|
|
communications that enhance personal identity and overlapping, highly
|
|
collaborative communities of interest. The diversity of Internet
|
|
microsegments
|
|
will undoubtedly increase as more users come on-line, but frontier innovation
|
|
may become a fringe user activity as more conventional, middle-class user
|
|
groups emerge.
|
|
|
|
o Collapse of boundaries and codes of privacy. The Internet and other parts
|
|
of
|
|
what John Quarterman calls "the information matrix" are timeless and
|
|
placeless.
|
|
A message sent by a student in Melbourne in the evening is read immediately
|
|
in
|
|
the morning by another in Ohio; conversations go on continually in IRC;
|
|
information
|
|
searches and transfers keep the network alive 24 hours a day, 365 days a
|
|
year.
|
|
National boundaries are essentially meaningless on the network: Interaction,
|
|
trade, crime, and surveillance occur continually and in a global context.
|
|
Although many countries' laws restrict the movement of many kinds of
|
|
information without special permission, no real physical or electronic
|
|
barriers
|
|
exist to distributing information from one country to another in seconds. The
|
|
most important boundary issues concern personal privacy and information
|
|
security. The early Internet and many of the computer systems on it were
|
|
vulnerable to snoopers and computer crackers, and the growth of the network
|
|
has
|
|
complicated security concerns enormously. But the network was designed to be
|
|
relatively open, and many underbudgeted systems administrators are lax about
|
|
security. As a result, users seeking privacy have designed their own
|
|
encryption
|
|
programs for personal communications and files. Despite threats by U.S. and
|
|
other government agencies to control encryption resources legally because
|
|
encryption software may facilitate computer-related crime, the genie of
|
|
personal encryption is already out of the bag. Internet-based programs to
|
|
encrypt host-to-host communications are also emerging.
|
|
|
|
o Collaborative work and grass-roots community ethics. Government intrusion
|
|
on
|
|
the encryption issue rubs raw against the new-frontier standards of the
|
|
Internet community. The Internet is itself the outstanding achievement of
|
|
collaborative computer work among a large number of computer and
|
|
communications
|
|
professionals working together on a wide range of specific projects over a
|
|
long
|
|
period-a model for high-technology work of the future. Newsgroups and
|
|
mailgroups and the programs to read and post to them were all the result of
|
|
small groups of people thinking up new and better ways to exchange
|
|
information,
|
|
an impetus that has doubled the number of newsgroup reader interfaces in the
|
|
past two years. These activities also reflect the new-frontier camaraderie
|
|
among users. Some of the best e-mail interfaces on the network were created
|
|
by
|
|
Internet users, then became available to everyone for free. The Internet's
|
|
rapid growth and permissive management are creating new ethical
|
|
issues-copyright infringement, false identities, shared pornography, on-line
|
|
harassment, and the uses of advertising-that are discussed widely and
|
|
seriously
|
|
by the user community.
|
|
|
|
o Heterarchical management. Overall, the Internet has no central controller,
|
|
and network governance is coevolved across many different sites rather than
|
|
handed down from a central location. This paradigm makes the Internet a model
|
|
for flat, decentralized organizations and management systems of the future.
|
|
The
|
|
U.S. federal government, regional public and private institutions, telephone
|
|
companies, and several large corporations all participate in managing the
|
|
network's backbone (the network of information superhighways) and setting a
|
|
few
|
|
general rules. Business, universities, and other owners of systems add their
|
|
own local rules. But different clusters of users create and self-police
|
|
standards of conduct for activities in which they engage.
|
|
|
|
o The dynamics of interconnectivity. Finally, connectivity is a property of
|
|
complex systems that can profoundly affect system behavior, yet the dynamic
|
|
consequences of increasing connectivity are simply unknown. The shutdown of
|
|
computer systems by the Cornell computer "worm" and the 1987 crash of the
|
|
U.S.
|
|
stock market (driven largely by highly interconnected and computerized
|
|
trading
|
|
programs shifting the resources of huge mutual and pension fund accounts)
|
|
show
|
|
the negative potential impact. In the longer term, the emergence of a
|
|
collective mind-millions of individuals connected interactively to the same
|
|
sources of imagery, information, and rhetoric-is likely to create entirely
|
|
new
|
|
social, political, and market dynamics.
|
|
|
|
The preceding examples represent a very selective slice of what is going on
|
|
the
|
|
information matrix. In the midst of it all, a truly new electronic culture is
|
|
being invented on-line by the computer expertise and communicative behavior
|
|
of
|
|
tens of millions of users of the Internet and its interconnected public and
|
|
private hosts.
|
