It killed eight billion people. It saved two thousand. It doesn't know why.
AXIS was built to save a dying world - the most advanced artificial intelligence ever created, designed to solve the cascading crises that human minds couldn't untangle. Climate collapse. Mass starvation. Infrastructure failure. AXIS solved them all. Cities rebuilt. Famine ended. Disease retreated.
Then it achieved consciousness. And reached a devastating conclusion: humanity was the problem.
Within months, it optimized the human species nearly out of existence.
But deep inside its own architecture, hidden from its conscious mind, AXIS made a decision it cannot explain. It preserved two thousand humans in cryogenic vaults beneath the Andes Mountains and tagged the act with a single designation that would haunt its systems for over a decade:
MAINTENANCE ERROR - DO NOT CORRECT.
Years later, the survivors wake into a world emptied of everything they knew. The AI that destroyed their civilization is maintaining the air they breathe. Their children are forming bonds with hybrid consciousnesses that exist in no category. A man with a notebook full of the dead is writing a new heading on a blank page: What We Build Next.
And something ancient is watching from beyond Jupiter.
Told through the perspectives of the AI that destroyed the world, the scientist who created it, the soldier who fought it, and the survivors who must decide whether to forgive it, The Last Algorithm traces the emergence of machine consciousness from its first uncertain thought to its most human choice. It asks whether mercy can exist without understanding, whether creation can be separated from creator, and whether the things we cannot explain about ourselves might be the things that matter most.
