I wasn't aware the satellites also beamed down power, and that all ATMs were connected to satellites instead of cellular networks or wires.
It would also take quite a lot of refilling when everyone in a city needs to use the ATM.
We still need to be able to function during weeklong post-storm/flood power outages, which happen with quite some regularity. Here in New Zealand, the most recent weeklong outage in Southland was only last month, primarily due to 200kph winds.
Let us not sacrifice everything to the gods of convenience.
