I was thinking about one of the James Burke TV programs that examined the 1965 northeast blackout. Same thing, where a single error (incorrect breaker setting) brought down power to 80,000 square miles of real estate in two countries

By removing physical media (bank notes) altogether, every-freakin-thing is dependent on the data network. This is less then reassuring in view of the near weekly data breaches in the news.

EDIT: The power just went out here. Still have cell service
