This seems vastly worse than "kings who were not professional soldiers" or "...not good governors".

If the minister had never done cyber-security work, I would understand. If he had never done any kind of technical computing at all, I would basically understand.

But to have never used a computer? That's like administration by a king who has never seen uncooked food or left his palace. Past a certain point you have so few referents that expert advice becomes unintelligible. There's precedent here too, but it's the precedent of puppet kings and court intrigues - leaders who either do nothing at all or make their decisions without regard for any concrete facts.
