Why the Digital Age?
Why does digitization matter? What do people mean when they talk
about the Digital Age? What does Nicholas Negroponte,
director of MIT's Media Lab, mean by "being
digital"?
Digitization simply is the destabilizing technology that is
causing all the "trouble." And much of the excitement. Because of
digitization:
-
We can make true, dependable, exact copies repeatedly. In the past when objects were either handmade or manufactured, there
were individual differences in production and creation, while with digitization every copy
is close to identical with very high fidelity even after use. This is why, for
instance, CDs have such good sound. They're digital recordings. You can buy a
used CD and assume it will be nearly as good as new, which you cannot assume with a
second-hand record.
But along with much greater standardization, there is no "original" anymore in
the sense of the first in a series or an authentic prototype. A thousandth digital
copy is just as good as the first. The first issuance of Windows 98 won't be any
different than the millionth. There aren't going to be recalls or
"lemons." Digitization is nearly perfect.
And anyone can do it. Anyone can make perfect copies of something digital, provided
they have the right, relatively low-cost equipment (such as a PC). We don't need
factories and manufacturing plants and specialized training. This is an instance of
the way in which digitization democratizes, a way in which digital
information empowers individuals (see below)
-
We can commingle bits, by which Negroponte means that we can combine
all kinds of digital information -- whether it be text, numbers, sound files, audio files,
a telephone call, a personnel record, or an image -- and make new forms of media.
One of these forms of media is called multimedia, which means that more
than one medium has been combined with some degree of interactivity.
Interactivity means that the user has some control over the reception and
use of the information. Without an element of interactivity, multimedia wouldn't be
more than, for instance, a slide show or an extension of filmmaking.
Hypermedia means that we can interactively choose to follow certain paths or
threads set up for us in a hypermedia environment. Navigation need not be linear.
Any of the elements of multimedia can be hyperlinked, such as text, images, and
audio/visual clips.
-
We can customize information to use it whenever and wherever we
want. With a great degree of interactivity, we can go much further than
"time-shifting," or watching TV when we choose through home videotaping.
Since digital information can be stored in a small space and can be recombined with other
digital information or data, we can search, retrieve, and store information in new
ways. This capability has broad-ranging implications for society and industry,
affecting everything from education to the military, art and music to banking. The "smarter" machines become or perhaps
the more emotionally
responsive they become, the more they can assist us without a steep learning curve or
ineffective manual labor on our, the user's, part.
-
We require less space for more information. Digital information is
lightweight and portable. A book obviously is heavier than a floppy disk.
Laptops are getting smaller and lighter, easier to travel with. Wearable computing is being
developed, so that it's possible to have an advanced Personal Digital
Assistant with you at all times. Speech recognition may
mean that we aren't limited to a keyboard; we can speak to the computer naturally and work
"on the fly." With Virtual
Reality, it's possible to have goggles in place while at work on a task, to use VR as
you need it (for instance in engineering, surgery, and other applications that are data
intensive and specific).
-
We can merge televisions and computers, through which we can share multimedia on the
Internet. This breakdown of the old communication divisions is known as media
convergence. We see this on the high end with High Definition Television,
or HDTV, and on the low end with WebTV. If we can have televisions that receive
digital signals, which the FCC has stipulated must happen
by 2006, then screens are likely to be developed with such high resolution that
reading from television at a close distance is possible. We will be able to share
"television" the way we now share information on the Net. Teleconferencing
will be available to all who can receive and transmit digital signals.
But with the convergence of television and computer and the breakdown of the old
categories between broadcasting, print, cable, and telephone come sweeping changes
that regulation must address. The FCC was created in 1934 to address
conditions of media scarcity. One of its charter missions was to prevent media
monopolies in selected markets so that no one voice could dominate (in other words, to
ensure democracy and fair competition). Today, however, we have media
abundance. Despite the a general trend toward government downsizing, the FCC has to
reinvent itself to meet current need. Because of digitization -- because of digital
media's ease of use, portability, facility, and availability -- the old laws based on
atoms, as Negroponte says, are becoming obsolete: Or are are they?
-
We have a universal means of transmitting information. When we speak of
digitization, we're speaking of zeroes and ones, on and
off signals. A digit is a bit of information; eight bits is a byte.
Negroponte often contrasts analog and digital, atoms and digits. By
analog,
he means transmitted by waves or through exact equivalence: I give you a piece of paper in
exchange for another piece of paper, or I send you a soundwave and you receive it as a
radio signal. With digital data, the information is broken down into digital code,
zeros and ones, and transmitted as bits in chunks called "packets" to be
reassembled on the other end. Every bit of information can be so dismantled and
recombined, as mentioned above. A modem, for instance, converts the analog code sent
over telephone lines and converts the information into the digital code read by computers.
When Negroponte contrasts the world of atoms with that of bits, he is
referring to the fact that the digital world seems unreal compared with the
"real world." What we do online and in electronic environments is
taking place literally in digital code. It isn't real, in the sense of one piece of
paper being handed from one human being to anothe; rather it's coded. But in fact,
we've had coded communication since the
telegraph of the mid-19th century. We know people online that we don't know
face-to-face, just as we know some people we talk with frequently on the phone, but never
meet. The term "virtual reality" is intended to evoke this sense of being
simultaneously real and unreal. But Negroponte goes a bit further. He would
like us to free up more of the time and energy that we invest in the real world to
perceive and make better use of increasing digitization. Negroponte is an evangelist
of digitization and its possibilities.
-
We can empower the previously disenfranchised. In order for digitization's
potential to have far-reaching impact, much of the world has to be wired.
This is taking place. Some developmental countries that skipped television,
or perhaps even the industrial revolution, may be going straight to digitization without
some of our regulatory precedent holding them back. The impact of digitization on
countries in formative stages, such as those in the former Soviet Union or the Third
World, is only beginning to be felt and studied. But here in our own country,
through digitization, some formerly underrepresented groups may have the possibility of
being heard in a way that was impossible when media production required specialized
equipment, specialized training, and expense. We cannot forget the "information
poor" in a world that increasingly is bifurcating into a new info-caste system.
-
We can benefit from the democratizing potential of digitization. When John Perry Barlow talks about how "information
wants to be free," this is what he's getting at beside anthropomorphizing something
inanimate and without volition. Information is accessible in ways that render
powerless the people who seek to contain it. Digitization has upset the
balance of power. Anyone can send a message to the president. Anyone
can set up a printing shop to expound his or her ideas, like the pamphleteers of the past,
but likely with more effective results. The Internet itself grew because people
enjoyed communicating with each other. Although it started as part of ARPANet,
the military-industrial-research network of the 1960s, use of the Internet mushroomed in
the late 1980s-early 1990s because users simply liked it and popularized its use.
The media conglomerates didn't promote use of the Internet; rather they were and largely
still are threatened. The traditional media has been destabilized. Much of
what regulation is about is trying to put the genie back in the bottle. Digitization
has often been called the most powerful force for democracy since the
Declaration of Independence.
-
We have a new imaginative realm. At times it can be difficult to separate
the real from the digital. Is a cyber romance
with deeply felt emotions less real than one that takes place between two people who have
feelings for each other? If you buy and sell digital stocks, are they any less real
than money exchanging hands? How about a forged work of art: Is a fake Mona Lisa any
less real than a real one? How are we defining reality and falsehood?
Digitization brings to sharp focus our discomfort with the intangibles of reality, showing
us that the real world may be less solid than we want to think it is. A dollar bill, after all, is symbolic than we may
assume in that it's based on a nonexistent gold standard. Love can never be exactly
proven, but it can be felt whether in the real world (offline) or online.
-
We have new forms of illegal activity. Despite and because of its potential,
digitization carries with it the possibility of fraud, sabotage,
theft, and other forms of criminalality that have always relied on sleight
of hand and getting around identification detection. New forms of cops and robbers
will appear as the public, lawmakers, and commercial sector seek greater means of
verification within the digital world. We want to impose real-world standards
of authenticity on a technology that is notable for its mutability. For every gain,
there is a new method of circumvention, a new opportunity for outwitting the authorities,
a new "hack."
But the gains are too great to go without. For example, we need
electronic medical information so that it can be called up wherever health care
professionals need access: from the ER through surgery, recovery, outpatient procedures,
and shared in databases for medical researchers looking for cures and insurance companies
looking to contain costs. The risks of information being falsified or falling into
the wrong hands does not outweigh the gains of timely, accurate information on diseases and conditions
available as it's needed, recorded once (much less paperwork, which cuts down on errors
and expense), and shared throughout the world so that trends can be seen, diagnosed, and
acted on.
The ability to access and share knowledge so easily creates enormous potential that can be
used for good or ill. It's this potential that Negroponte wants us to see and not to
waste.
