They’re not unfamiliar with tools or technology. Explaining electricity might still be seen as magic… Shit I know how it works and it still seems pretty magical to me 🤷🏻♂️
Exactly, for the topic of cybersecurity you could take the metaphor of a fort that is under constant attack and has to be defended for example and you could explain it reasonably well to people who lived thousands of years ago.
