After years of lage advancements in robotics, the first real "humanoid" robot was designed. It was based on the human brain, and why not? It works pretty well. The huma brain is capable of calculations as large and as fast as any machine, just not every human brain. So, they produced a robot with a mechanical human brain.

It worked exceedingly poorly. After about 140 years, the robots all commited suicide within days of each other. Something new was learned. The human mind cannot survive for more than 140 years.
