It's important to keep in mind the reactors at Fukushima were designed in the 1960s -- literally fifty years ago. During that same time period, we were doing things like designing machines for efficiently burning down the rainforest so we could open up land for farming, and pouring miscellaneous mixed nuclear waste into underground vats for future generations to figure out.

It might be debatable whether humanity is sufficiently responsible to maintain any dangerous machinery requiring generation-level planning, but it is important to keep in mind how far removed we are from the era in which every nuclear reactor ever having experienced a major nuclear incident was designed.
