Redemption Ark

The overseer did not exist in any single Inhibitor machine. That would have been too vulnerable a concentration of expertise. But when a swarm was drawn to the site where a local cleansing would be required — typically a volume of space no more than a few light-hours wide — a distributed intelligence would be generated from many less than sentient subminds. Light-speed communications bound together the dumb elements, weaving slow, secure thoughts. More rapid processing was assigned to individual units. The overseer’s larger thought processes were necessarily sluggish, but this was a limitation that had never handicapped the Inhibitors. Nor had they ever attempted to weave together an overseer’s subelements with superluminal communication channels. There were too many warnings in the archive concerning the hazards of such experiments, entire species that had been edited out of galactic history because of a single foolish episode of causality violation.

The overseer was not only slow and distributed. It was also temporary, permitted to achieve only fleeting consciousness. Even as its sense of self had come into being it had known with grim fatality that it would die once its duties were accomplished. But it felt no sense of bitterness at the inevitability of this fate, even after it had sifted through archived memories of its previous apparitions, memories laid down during other cleansings. It was simply the way things had to be. Intelligence, even machine intelligence, was something that could not be allowed to infect the galaxy until the coming crisis had been averted. Intelligence was, quite literally, its own worst enemy.

It found itself remembering some of the earlier cleansings. Of course, it had not really been the same overseer that had masterminded those extinction episodes. When Inhibitor swarms met, which was rarely, they traded knowledge of recent kills and outbreaks, methods and anecdotes. Lately, those meetings had become more rare, which was why there had been only one significant addition to the library of starcide techniques in the last five hundred million years. Swarms, isolated from each other for so long, reacted cautiously when they met. There were even rumours of different Inhibitor factions clashing over extinction rights.
