One
of the most fascinating subjects of present-day information technology
is called multimedia.
A first step is formed by upgrading linear word processing to hypertext.
Storing fragments of text in which all kinds of links can be applied,
so that it becomes possible to create ones own story, as it were. When
applied to this piece of work, for instance, it would mean that you
are not obliged to read it from start to end, but that you could create
your own fantasy version. The question is whether this is merely fun,
or actually useful.
To make things even more spectacular, we can add photographs, sound
fragments or even video clips. A further perfection of the virtual prison
in which we are already living, under the impression that we are free.
With multimedia, however, man is still a spectator, with or without
identification. The next step consists of making connections between
the computer and our body. Participants are wrapped in all kinds of
special instruments, such as spectacles and gloves, with two-way connections
with the computer. A simulated reality is visualised on our retinas,
different images for either eye, even. With such interaction, man is
as it were (caught) inside the machine. Computer freaks have given this
new discipline the almost magical name of virtual reality.
On the one hand, we are offered a technology to open up large quantities
of data of various nature, but on the other hand, there is an enormous
threat that everything will be related to everything. In stead of storing
acquired knowledge (or systematic relationships) we are storing manifestations
(or occurrences, in computer terminology) of that knowledge. Digital
cameras, scanners, cassette recorders and computers are unravelling
reality into zeroes and ones. Subsequently,
these data packages are jostled together, whereupon they are distributed
and communicated by means of multifunctional telephones, television/computer
combinations and super hi-fi installations with digital technology.
With this kind of automation it is wise to remember the central theme
of the teachings of Krishnamurti: The description is not that
which is described[25]. For before
you know it, you will have built a computer analogy of Platos
cave[26]. You know, the myth in which
Plato tries to explain to us that we usually confuse the shadows of
things with the actual things.
