内容简介
In the beginning, there was darkness. In this Age of Innocence, the unwashed masses practiced the art of
entertainment with small pieces of paper bearing symbolic images of kings, queens, and jesters. Sometimes,
they used minute pieces of metal and plastic, shaped like various real-world objects, moving them about on
large, colored cardboard sheets in accordance with the runes inscribed upon small white cubes. To the casual
observer, all was content, but in the minds of the newest generation born of this age, there was a yearning for
more. Unbeknownst to the world, this yearning grew, and soon these young pioneers began working in the
dark recesses of colleges and universities to bring about a change that would alter the course of history in
ways no learned scholar could have ever imagined. Brandishing vacuum tube sabers and using arcane words
of power such as RAM, ROM, Bit, and Byte, these acolytes of technology brought forth a new creation
known as the Computer. But, their new creation was naive, and lacked intelligence or sophistication; to
control it, they had to use a mystical, magical language known as Code. Thus, the Art was born, and a new era
had begun.
The First Age was marked by the genesis of immense, hulking beasts that required enormous resources to
sustain life. These new life forms were rare, but typically stood several stories tall and required incredible life
support systems to maintain an agreeable environment. These giants were moody and possessed little
intelligence, but through great effort, they could be trained to perform incredible feats, for their day. The
digital landscape was dotted with few of these behemoths, and their trainers were monk-like in their
dedication. Unable to break free of their confines due to the immense size of their charges, these monks were
forced to toil maddeningly long hours. Their torturous task of preparing the vegetarian meal of holy leaves
consumed by these monsters had them working late into the night, and the Art required to create these holy
leaves was arcane indeed.
These monks practiced the great Art in the same dark recesses from whence it was conceived, and the Art
grew. The once young pioneers had become pedantic, wizened old masters. These old wizards were still
rebellious and, yearning for a new form of entertainment, they used the Art in ways that the Powers That Be
felt were unproductive. Away from the watchful eyes of their overseers, they shaped the Art in ways that
previously existed only in their dreams.
In the dark hours of the morning, these masters used the Art to coax the new creations into providing their
long-sought-after entertainment, and they played games such as Tic-Tac-Toe and Pong. Several of these
wizards used the Art to create much more sophisticated forms of entertainment, and played games such as
Checkers and Chess with their silicon automatons. In the wake of the First Age, walking in the shadow of the
evolving Art, a new form of the Art began to grow.
Like dinosaurs, the reign of these behemoths was relatively short-lived. A new catalyst known as the
Corporation had used the knowledge learned in the First Age to effect an evolutionary step known as the
Home PC. Thus, the Second Age began.
In the Second Age, the pantheon of overlord gods began to form, controlling the evolution of this new
creation from on high. Deities known as Gates and Jobs worked their mystical creation power behind the
curtains of reality, but their new creations were protozoan in nature. A step back from their massive
predecessors, these new single-cell machines were much less sophisticated and powerful, and teetered on the
edge of extinction almost as soon as they had appeared. However, these new creatures had become visible to
the unwashed masses, and began to elicit their attention. At first, few of the Untrained could afford to adopt
one as a pet, but their popularity grew, and soon many of these creations made their homes on desktops in
homes and businesses. The Art, still arcane in nature, had begun to emerge from its dark recesses, and several
of the Untrained began to delve into its mystical powers.
The Net, the once-dark netherworld populated solely by the wizards and masters of the Art, has now become a
tourist attraction, replete with amusement parks, rest stops, and gift shops. Rumors of new CPUs with speeds
in excess of 1,000 MHz are being whispered in the dark corners of cyber cafÈs and coffee shops. Thus, we
stand at the dawn of yet another New Age. As the sun breaks over the distant horizon, its golden, shimmering
rays cascading over the silicon juggernaut that stands before us, the prospects of the future are at once both
exciting and frightening.
Thus, our journey begins.
