"We didn't just build a drone," Derek told the audience, his confidence growing. "We built a hive mind—a system so intelligent it learns from the air itself."
Jaime watched, her expression unreadable. She checked her watch: it was 10:05 a.m.
"And now," Derek announced, sweeping his arm toward the massive glass wall behind him that looked out over the testing field, "witness the future."
A swarm of 500 drones lifted off from the tarmac outside. It was breathtaking. They moved like a liquid silver cloud, shifting and undulating without a single collision. They split into groups, picked up packages, and weaved through a complex obstacle course of skyscrapers and moving trucks. The crowd gasped. The efficiency rating on the giant screen hovered at 98.5%.
"Perfect," Gavin whispered from the side of the stage, checking the stock price on his phone. It was skyrocketing.
In the library, Jaime opened a terminal window on the public computer. She wasn't hacking them; she didn't need to. She simply accessed a public API that tracked local air traffic data. She watched the telemetry of the drone swarm.
"You commented it out, didn't you?" Jaime whispered to the screen.
She knew Jessica Vance. She knew the type of engineer Jessica was: arrogant and efficient. When Jessica saw the sigma variable $\sigma$, defined as a time-dependent function in the math, she would have assumed it was a bug or a testing limitation. She would have cleaned the code by setting $\sigma$ to zero or removing the dependency.
But Jaime hadn't written code; she had written topology. The sigma variable wasn't a line of code you could delete; it was the mathematical anchor for the coordinate system. By removing the variable, Jessica hadn't disarmed the trap—she had removed the brakes.
The equation Jaime wrote relied on $\sigma$ to reset the negative space values every 300 seconds. Without the reset, the value of empty space would exponentially increase in the drones' logic. Basically, the drones would start believing the world was getting smaller.
Jaime watched the timer on the livestream.
Time elapsed: 4:58.
Time elapsed: 4:59.
"Boom," Jaime whispered.
On stage, Derek was basking in the applause. The drones were returning for the synchronized landing, the grand finale where they would form the Aerologics logo in the sky.
"As you can see," Derek said, "safety is our priority. Our collision avoidance is flaw—"
He stopped. A murmur rippled through the crowd.
Outside the glass, the swarm faltered. The fluid motion snapped. The drones didn't crash; they shuddered. Then, instead of landing, they accelerated.
"What is that?" someone in the front row asked. "Is that part of the show?"
The drones were converging. They weren't forming a logo; they were rushing toward a single point in the center of the airfield—a point that, according to the corrupted math, was the only safe space left in the universe.
"Jessica!" Derek shouted into his earpiece. "What's happening? Abort! Hit the kill switch!"
"I can't!" Jessica's voice screamed in his ear, deafening him. "They're not responding to the server! They're locked in a recursive loop!"
The swarm condensed. 500 metal drones, spinning at 40 mph, slammed into each other in a catastrophic singularity. It looked like an imploding star made of plastic and lithium batteries.
Crunch.
The sound was loud enough to vibrate the glass of the exhibition hall. The ball of tangled drones, now a fiery mass of grinding rotors and exploding batteries, lost lift and dropped like a stone straight onto the VIP parking lot—specifically onto a Tesla Model S Plaid.
The explosion shook the floor. Black smoke billowed up, obscuring the view.
The silence in the hall was absolute. Then the screaming started.
The stock ticker on the giant screen behind Derek froze, then turned bright red as the algorithm halted trading due to the massive sell-off. Derek stood center stage, his mouth open, watching his career burn in a heap of scrap metal.
Gavin Reed ran onto the stage, not to help Derek, but to grab the microphone. "Technical difficulties! A minor calibration error! Ladies and gentlemen, please remain calm!"
But no one was listening. The investors were already on their phones, screaming at their brokers to sell. The reporters were flashing photos of the burning wreckage.
In the library, Jaime closed the browser tab. She stood up, stretched her back, and walked over to the circulation desk. She returned her visitor pass. She didn't smile. It wasn't funny. It was a waste of beautiful engineering, but they had asked for a solution, and she had given them one. They just hadn't paid for the instruction manual.
Jaime walked out of the library and into the gray afternoon. Her phone buzzed. She ignored it. It buzzed again, and again. She pulled it out: unknown number. She knew who it was.
She answered: "Hello?"
"You ruined us!" Derek's voice was hysterical. "You crazy bitch! You crashed the swarm! I'm going to have you arrested! I'm going to—"
"You crashed the swarm, Derek," Jaime said calmly, walking toward the bus stop. "You removed the sigma variable, didn't you? You tried to bypass the reset loop because you didn't understand why it was there. You thought you were smarter than the math."
"Fix it!" Derek screamed. "The board is convening in an hour! Gavin is talking about fraud charges! Fix it, Jaime! I'll pay you! I'll pay you the 5,000!"
