Ask HN: Tech Literacy Course Topics

I am exploring making a "tech literacy" course for children, that is "career-hopeful" agnostic. Age isn't as relevant as inexperience with computers is but for simplicity's sake you could aim for a 12yo child who has taken a typing class.

I have lots of ideas but don't want to predispose anyone to topics, rather get their raw opinions on what might be covered. Feel free to share anything from just a single topic (i.e. encryption) to an itemized list.
