As a society we had a much higher tolerance for risk when the electrical grid was being built. We were perfectly fine with the idea some people would die building it and some people would get electrocuted using it. The world we live in now has much lower tolerance for risk. You can't even screw a wall mount bracket in without carrying liability insurance.

A major reason for needing to have so much liability insurance in the United States is the insane cost of our medical care.

Society's risk tolerance varies with domain. Electrical power systems are well understood and thus we expect them to be as safe as practical.

Contrast that to the reaction to Tesla's autopilot that will happily drive you into an embankment at fatal speeds.

[BlueTemplar]

Electric power systems are much more dangerous than communication networks.
