The equation Jaime wrote required the swarm to reset its idea of empty space on a clock. Without that reset, the definition of safe air did not stay stable. It shrank. For the first four minutes the demonstration was beautiful, because the error had not yet compounded. At minute five, the silver cloud hesitated. The efficiency number on the giant screen flickered. A package dropped. Then another. The drones, each one looking only for the space where the others were not, began to agree on a single remaining coordinate. They converged. Not in a graceful turn. In a collapse. Five hundred machines tried to occupy the same point in the air above the exhibition field. The sound reached the hall a half-second after the picture. Metal on metal. A silver rain. The stock ticker Gavin had been watching stopped climbing and fell through the floor of the graph. Derek stood on the stage with his arm still extended toward a future that had just hit the tarmac. Gavin was already on his phone, and he was not calling a waitress.
By evening the board had been pulled into the glass tower. The room was the kind of mahogany silence money buys when it is frightened. Arthur Blackwood sat at the head of the table, the chairman who had not been in the room when a napkin was erased. Robert Patterson, outside counsel, sat with a folder he had not yet opened. Jessica Vance looked at her hands. Derek looked at the table. Gavin looked angry, which was his version of a plan. The side door opened, and Jaime Jenkins walked in wearing a thrift-store blazer and carrying nothing but a pen. The temperature in the room seemed to drop.
“Mr. Reed,” Arthur said, his voice dangerously soft. “Is this true? Do we not own the IP for the swarm logic?” “We own the code,” Gavin insisted, slamming his hand on the table. “Jessica wrote the code.” “I wrote the topology,” Jaime cut in. “Jessica just translated it into C++. But she did a bad job. She removed the sigma variable.” Jaime stood up. She walked to the whiteboard at the end of the room, the same kind of board Gavin had erased a day ago. “The crash today wasn’t a hardware failure,” Jaime said, picking up a marker. “It was a mathematical certainty. Your drones operate on a negative-space protocol. They don’t look for obstacles. They look for empty air. But without the sigma variable to reset the local coordinate system every few minutes, the definition of empty air shrinks.” She drew a quick graph, an exponential curve dropping into zero. “By minute five,” Jaime said, tapping the board, “the drones calculated that the only empty space in the entire world was a singular point in the center of the swarm. They didn’t crash. They were trying to hide in the only safe place left. They were trying to occupy the exact same coordinate simultaneously.”
The board stared at the board. It was terrifyingly simple. “You built a suicide pact into the firmware,” Arthur Blackwood murmured. “I built a safety valve,” Jaime corrected. “You removed the handle.” “We can patch it,” Jessica spoke up, her voice trembling. “Now that we know, we can patch it in a week.” “No, you can’t,” Jaime said. She turned to Jessica. “Because the sigma variable isn’t constant. It’s dynamic, based on the hardware heat signature. It requires a distinct coefficient for every single drone unit. If you guess wrong, they don’t crash immediately. They crash randomly. Maybe in five minutes. Maybe in five hours, over a playground. Are you willing to take that liability?”
Silence choked the room. Robert Patterson leaned back in his chair and smiled. It was a shark’s smile. “Ladies and gentlemen of the board,” Patterson said, “here is the situation. You have a warehouse full of drones that are effectively paperweights. You have a stock price that is currently in freefall. And you have a creator who is willing to walk out that door and sell the solution to Amazon or Google tomorrow morning.” “This is blackmail,” Gavin hissed. “No,” Jaime said. “It’s business. Isn’t that what you told me, Gavin? Leverage is everything.”
