Corvallis and most of the other techies hated this idea because of its sheer bogosity, which was screamingly obvious to any person of technical acumen who thought about it for more than a few seconds. If their pattern-recognition software could identify the moving travelers and vectorize their body positions well enough to translate their movements into T’Rain, then it could just as easily notice, automatically, with no human intervention, when one of those figures was walking the wrong way and sound the alarm. There was no need at all to have human players in the loop. They should just spin out the pattern-recognition part of it as a separate business.
