The Shockwave Rider by John Brunner Page A

processing techniques at the expense of his other study subjects, but about one in four of his contemporaries had by then also evinced a preference for some specialty, and this was a valuable talent. (It had been explained to him that in terms of n-value mean-path theory administering the three hundred million people of North America was a determinate problem; however, as with chess or fencing, it was no good to be told that there must be a perfect game if the universe wouldn’t last long enough for it to be found by trial and error.)
    He had been reserved and self-contained when he arrived. It was not inconsistent that after a gesture in the direction of greater openness he should revert to his old solitary habits. Neither his teachers nor his friends guessed that he had revised himself for a purpose. He wanted out, and there was not supposed to be an out.
    The point was never labored, but there were constant reminders that to support one student at Tarnover cost the federal budget approximately three million dollars per year. What had been spent in the last century on missiles, submarines, the maintenance of forward bases overseas, was now lavished on these secret establishments. And it was known in the subtle way such things can be known that a condition of being here was that ultimately one must offer the government a return on its investment. All the graduates who came back to visit were doing so.
    But the conviction had gradually grown in Nickie’s mind that something was amiss. Were these people dedicated … or insensitive? Were they patriotic … or power-hungry? Were they single-minded … or purblind?
    He was determined that somehow, sooner or later, before committing himself to the lifetime repayment they were bound to demand of him, he must break loose long enough to take a detached view and make his mind up about the rights and wrongs of the brain race.
    That was what set him on the trail of what he later found to be a 4GH code.
    He deduced from first principles that there must be a way of allowing authorized persons to drop an old identity and assume a new one, no questions asked. The nation was tightly webbed in a net of interlocking data-channels, and a time-traveler from a century ago would have been horrified by the degree to which confidential information had been rendered accessible to total strangers capable of adding two plus two. (“The machines that make it more difficult to cheat on income tax can also ensure that blood of the right group is in the ambulance which picks you up from a car crash. Well? ” )
    Yet it was known that not merely police informers, FBI agents and counterspies continued to go about their secret business, but also commercial spies—party agents shepherding million-dollar bribes—procurers serving the carnal purposes of the hypercorps. It was still true that if you were rich enough or had the ear of the proper person, you could avoid and evade. Most people were resigned to living wholly on the public level. He was not. He found his code.
    A 4GH contained a replicating phage: a group which automatically and consistently deleted all record of a previous persona whenever a replacement was keyed in. Possessed of one, an individual could rewrite him- or herself via any terminal connected to the federal data banks. That meant, since 2005, any veephone including a public one.
    This was the most precious of all freedoms, the plug-in life-style raised to the n th power: freedom to become the person you chose to be instead of the person remembered by the computers. That was what Nickie Haflinger desired so keenly that he spent five years pretending he was still himself. It was the enchanted sword, the invulnerable shield, the winged boots, the cloak of invisibility. It was the ultimate defense.
    Or so it seemed.
    Therefore, one sunny Saturday morning, he left Tarnover, and on Monday he was a life-style counselor in Little Rock, ostensibly aged thirty-five and—as the data-net
