I used to design devices for military satellites that had to withstand a 1 megarad radiation dose from an atomic bomb, so I have some knowledge of what this stuff does to electronics.
Many cars would still be running, for example, in contradiction to the movies and fiction books about EMP.
Now that is interesting to know.
I had understood that only those electronics in Faraday cages would still operate.
Still though, I don’t want a smart gun. I don’t want my gun thinking, I only want it to obey.
