I have to admit that you need to have at least basic knowledge of computer science, network and telecommunications + some historical knowledge as well. If that's the case, you will really enjoy this masterpiece, I really loved this and considered this anime as a must if you like the anime. Nevertheless, if you have no knowledge about those topics I think it will be kind of confusing to become boring maybe.
As personal opinion this is masterpiece anime but not made for everyone.
