The
scene at the end of the film Ghost in the
Shell depicts the main character integrating herself with the global
network. Her personality subsumed, the
assumption is that the meeting of the ‘minds’ results in a dilution, an
absorption, the individual personality effectively vanishing into the uber-mind
of the net. Joan D. Vinge, in her 1979 novella Fireship, takes the idea of combining personalities in a different
direction: schizophrenia.
Michael
Yarrow is an ordinary man living on Earth, that is, until agreeing to have a
jack installed in his lower spine and AI attached that interfaces with his
mind. The AI named ETHANAC 500, the decision
results in three personalities: Yarrow, the AI, and a combination of the two, a
personality which calls itself Ethan Ring.
Dominance of one over the others dynamic, the man wanders through life
in a semi-spastic state as each personality pushes and pulls at control. Able to maintain the appearance of sanity,
Ring commits a crime to escape his situation and lands on Mars to elude the
law. Staying at the luxury casino
Khorram Kabir, his singularity is all too quickly discovered. Threatened with being revealed to the police,
Ring is blackmailed into helping a mysterious organization dig into the
casinos’ inner workings, particularly its secretive owner. Putting his personalities to the test, what
results is a suspense-filled story that threatens to tear Ring into his three
different selves.
