One has only to look at the disastrous  power outages
caused by storms in Victoria from  Tuesday 13 February
and Thursday 22 February this year in order to see how
even a breakdown in one area of technology can cripple us
socially.

No perishable foods available; no ATMs functioning; libraries,
post offices, and banks closed; cafes and hotels closed; petrol
stations closed; no VoIP (home phone) access; no internet access;
no 4G phone access; no street or security lighting, unable to
call fire or ambulance etc.

We were in the dark—literally—for 3½ days.   Not good enough
in "the lucky country".
