I think constantly how to make them "the correct amount of paranoid". I made a lot of mistakes, and I will try to at least use them as a kind of real-life example of what can go wrong (assuming I'll be able to have an honest an reasonable relationship with them).

I also think that introduce them to the rudiments of programming and informatics could be beneficial because they could endogenously develop a curiosity about the issues and weaknesses of the current digital world we are immersed in.

On the other hand, I believe the most difficult obstacle will be peer pressure. I genuinely do not know what I would do if my kids would be in a position of being excluded because they don't have phones/social media. I know what I should do ideally, but the details and potential consequences I can not reasonably predict are too many.

Concerning moving, I get that it would help if an address is leaked, but it's obviously a non-solution to (what I believe is) the vast majority of people suffering from these data breaches since work/life flexibility is kind of a "luxury".
