Under the guise of protecting the grid from an EMP attack, it would seem well worth it. I’ve seen estimates shared here, but drawing a blank at the moment. Seemed dirt cheap, relatively speaking.
I also recall seeing estimates posted on HN one time, but can’t find the source. I seem to remember $500m ish. ‘Cheap’ insurance relatively speaking.
Thank you, that was the number I was remembering as well, but it seemed so crazy low I didn't want to repeat it. Even a dysfunctional U.S. Congress should be able to cough up that much money.
