Unfortunately, it's not that simple. Stuxnet showed us that offline networks can be attacked and have real-world consequences (e.g., exploding enrichment plants). Almost all of our critical infrastructure is offline, and many of our infrastructure companies air-gap their critical networks. Yet we are all still vulnerable simply because we are using computers.
