Turns out those tech bros were right. With the aid of AI, humanity achieved singularity. Well, the so called elite did. Yes, they were right, but they were also so wrong.
In typical elite fashion, the Singularity decided that ordinary humans were redundant and eliminated them.
Also in typical elite fashion it didn't understand what supported it and only thought short term.
The systems failed with nobody to replace them. Nobody was left to mourn the Singularity's end.
