My mother can't. You need a skilled, trained and informed team of technicians to do so.

In a dictature killing access to culture and education, it not weird to assume it is hard to breed those so you have a limited pool.

So yes, I understand the surprise. Which means NK has some resources we don't include in the picture.

One nerd is pretty much all it takes.

Certainly not. Creation, customization, maintenance and deployement at the scale of one country is a huge task.

That's not true. A single person can do it at world scale provided they are not trying to do something overly esoteric (though you can actually get pretty far with a Gentoo base). There are even plenty of from-scratch distros that started as a one-man show. Take the recent Void Linux for instance.
