I kind of get the worry, but the requirements and processes seem to scale exponentially with reliability needs. Online companies may fuck up every day in new and creative ways and we barely get to hear about it. On the other hand we know of every nuclear failure so far with enough public details to discuss the whole time line, system design, steps each person followed, etc. and the death count is still minimal. Then each of those is an input to the future processes. Nuclear power plants and air traffic are in their own class of reliability and safety processes - not even comparable to that's happening in internet commerce.
