Kenichi Ohmae wrote a great piece in the Christian Science Monitor citing why probabilistic models aided by multiple layers of homogenous redundancy can give a false sense of comfort:
The most important lesson of Fukushima No.1 plant, therefore, is that we should have a multiplicity of means to provide a continuous electric supply and heat sinks. This is not the same as “You should not put all the eggs in one basket.” We should have eggs and apples in a few different baskets.
True redundancy is inherently diverse and harder to justify on financial and operational fronts. It is easier to engineer quintuple failover of the same system, and thus we do.
