Thought-provoking article. I've found that useability (and mis-use) is the area that also deserves special attention when designing certain types of devices.

However, having the creativity to predict all of the mis-use cases that could possibly occur is challenging and takes an extra amount of time and mental imagination to really get it right up-front.
I think the statement, "Ironically, complexity is often added to a system to reduce common-mode failures" is true no matter what level of design you are at - from simple circuits to intricate systems - but at the system level the interactive nature of the subsystems can indeed cause some unexpected issues that are much more predictable in less complex designs. Interesting article with much food for thought...
