the only example that comes to mind is distributed / collaborative
anomaly detection systems which become more robust with a larger
number of entities and interactions to observe.

in such a scenario, the ability of the system to accurately "detect"
malicious activities or unusual failures would increase with the
complexity of the system.

[though this exposes a critical distributed component to attackers;
poorly implemented and you've got a global witty worm, or worse...]
