Why are you saying these things? They are not my words. I think society should be prepared for these kinds of downtimes because of external factors anyway. Cost effectiveness is not always a good thing and having reliable, fixable systems with non-computerised fallbacks should be desirable.
Or should people start dying as a result of, say, medical systems being hacked? (which is probably already the case, or at least the vulnerabilities are there since long back according to empirical studies)
