This article is bs in so many differnt ways it is scary. Someone pointed
out that it takes an H bomb to get these effects on a large scale.

That is largely untrue. Most areas came back up in a somewhat crippled
mode (rotating outages) on their own.

They are also just about the least likely to be damaged by
EMP. Transformers are protected against *lightening* strikes which are a
lot more energetic.

Right. 1880s with the Internet (which was designed from the start to deal
with attack, not to mention that optical fibers are just not affected by
EMP. (The electronics might be hurt.)

I doubt he wrote it, people at that level almost never do. But he isn't
going to get much credit from technical people for letting this go out with
his name attached.
There *are* real problems, some of which are just not talked about at all
because we don't know how to protect against them. We do need to consider
and plan for these problems, but EMP taking out big transformers is way
down on the list.
