The next morning, the AI logs showed a miraculous "self-healing" event at the pylon. Elias was promoted to Senior Architect, but he kept his old textbook on his desk. He knew that while the world looked at the sky, the real story was always written in the .
But Elias looked at the live feed of the main support pylon. He saw a microscopic pattern emerging on the surface of the smart-steel. To the AI, it was a texture. To Elias, it was waiting to happen. The manufacturing process of the latest batch of alloy had skipped a crucial isothermal transformation step, leaving the grain boundaries brittle. The Science And Engineering Of Materials (Intru...
Elias didn't argue. He went to the basement, bypassing the digital locks using a simple trick he’d learned about the of the lock’s magnetic sensors. He found the pylon and applied a localized thermal pulse using a handheld welder, manually inducing a precipitation hardening effect he’d calculated on his tablet. It was a localized patch, a temporary "scab" of atoms rearranged into a stronger lattice. The next morning, the AI logs showed a
An hour later, a massive gale slammed the city. The Needle swayed. Across the city, sirens wailed as other buildings developed hairline cracks. The Needle, however, held firm. The stress concentrations flowed around Elias’s patch, distributed perfectly by the he had forced into the metal. But Elias looked at the live feed of the main support pylon
