friends of yours, you knew, in your grief and shock, that they were statistical aberrations. The more you kept marching, however, the more difficult it became to ignore the fact that you were drawing close to the surface. People in front of you died singly, then in clusters, then in swathes. Eventually, when you were something like a hundred years old, you emerged from the trench onto open ground, where your life span was measured in minutes. Richard still had decades to go before it was like that, but he’d seen a few people around him buy the farm, and looking up that trench he could see in the great distance—but still close enough to see it—the brink above which the bullets flew in blazing streams. Or maybe it was just the music in his headphones making him think thus.
They passed a good restaurant—a favorite of Richard’s when he needed to host a business lunch. A box truck pulled out of the adjoining alley and inserted itself into a gap in traffic in front of the bus. It was decorated with the logo of a company that evidently provided table linens to restaurants that were classy enough to make use of them. Off the little truck went, headed for the next restaurant where it would make a delivery. The bus driver was annoyed by the manner in which it had claimed the space. Richard, ahead of schedule and not responsible for anything, just zoned out on the flow of traffic. As they passed the alley, he saw a beer truck unloading kegs of microbrew. The purposes of linen and beer trucks were obvious, being printed right on their sheet metal, but of course every vehicle on the street and every pedestrian on the sidewalk had a purpose as well. It was the flowing-together and interaction of all those intentions that made a city. The early failure of Corporation 9592’s game designers to capture that feeling had led to several months of Richard’s doing what Richard generally did, which was to attack problems so weird that merely to cop to their existence would have been career suicide for anyone who wasn’t the company founder. The name of the game, and of the imaginary world in which it was set, was T’Rain. The world’s geology had been convincingly simulated by a man who went by the name of Pluto and who was very gifted at that sort of thing. The urban landscapes had turned out to be much less convincing, for reasons not immediately clear. It was one of those problems assumed to be trivial that had turned out to be really hard. What it boiled down to, once they had spent millions of dollars flying people in for seminars and simulating urban traffic flows on supercomputing clusters, was that, in a real city, everyone had something they were trying to do. Sometimes everyone had a different goal, other times (as just before a big sporting event) everyone had the same goal. The way that people and vehicles moved reflected their pursuit of those goals. When you had spent some time in a real-world city, your brain learned to read those behaviors and to process and understand them as citylike. When you visited a made-up city in a massively multiplayer online game, however, you generally saw group behaviors that failed to match those that convinced your brain that you were looking at something real, and the illusion failed.
“Pill Hill,” which loomed above downtown, had long ago been seeded with several hospitals that had done nothing but grow and consolidate as the city had developed into a horn of plenty, morbidity-wise. The few spaces not claimed by the hospitals themselves had sprouted medical buildings, twenty and thirty stories high, all interconnected by skybridges and tunnels. That combined with mergers and consolidations had turned the hill into a fully interlocked, mile-wide, three-dimensional maze entirely devoted to health care. It was well served by mass transit. Richard could have taken the bus right to the entrance of the clinic. Instead he decided on the spur of the moment to get off several blocks early and enjoy a stroll down Cherry Street. The neighborhood was old by local standards, with mature maples that had presumably been imported by settlers who wanted it to look like the leafy towns of the northeastern and midwestern United States. The autumn color was peaking. His earlier musings had caused him to wonder, again just in an idle and non-gloomy way,
