As a "young person" (under 30), my thoughts: There's a minority of us that do genuinely care, possibly more than most - so hiring someone from this minority would be helpful - but the vast majority of my peers don't care about privacy nor security. They often take this defeatist mindset of "my data is already out there, why should I care?", or prefer convenience over security. For example, "why should I switch to Signal if I have a public Instagram profile?" or "I can't remember all those passwords! I just use one for everything."

As for your comment about junior engineers, see kennywinker's reply to this thread - I share the same thoughts.
