Automation reduces manual error by removing human intervention from repetitive operations. The same property that makes it reliable at scale makes it dangerous under failure: a misconfigured reconciliation loop or pipeline reaches every target simultaneously (FN-0002).

Implication:

Human operators fail slowly and locally. Automated systems fail fast and broadly. The reliability gain from automation does not reduce systemic risk; it concentrates and accelerates it.
