The problem I've experienced is that whenever I talk about software security with non technical people I get a lot of "I thought this dude was normal until he put on the tinfoil hat" looks and overall lack of interest.

The only time people become more aware of security is once they've suffered the consequences of a lack of security. To be fair, the only reason it concerns me is because I've been exposed to so many stories and somewhat have to deal with it in my field.

So it follows naturally that as incidents of security crimes and overreaching governments and corporations increase, then so will the awareness surrounding information security. It has to be actually happening to most for humans on a crowd scale to pay attention.
