If a system has critical safety components (using, or misusing the system could harm or kill people), all parts of it should be treated as such. This applies to hospital equipment, missile warning systems, cars, etc. Things like security and reliability rightly get a lot of attention, but UX is just as critical, as this event shows. There are plenty of case studies of poor UX on hospital equipment killing people[1]. When will people learn?
