If I was responsible for the cyber security of a whole country,
I certainly would stop using computers.
That's an entirely separate issue from whether a background in computers would be helpful or required.
One thing, you could get hacked, which would at best be embarrassing, and two, when your job is talking to people about important things, the fewer written records the better.
I once naively asked at work why we didn't simply record a regularly scheduled meeting and use voice recognition for a first pass at the notes, instead of having someone take them manually. Even in correcting them, it would be so helpful to be able to rewind and play back a recording. I got an withering look and a comment to the effect that people don't expect to be recorded.
It reminded me of how I read long ago that the official transcript of what is said in Congress gets extensively edited before it is final, even to the point of inserting speeches that weren't made in reality.
