If 14 year olds know more about the security vulnerabilities of our most highly adopted computer systems than the professionals which use and safeguard/build them, then it would say more about those professionals than the teens (a fact that I am highly sceptical of).

Or could it be a self reported survey says more about the perception of 'cool' subversive behaviours amongst that group than it's prevalence? I'd buy the latter over the former. You only have to wander around a university campus nowadays to understand the the days of overindulgence in drink/drugs are over -- and that being a self-identified entrepreneur or hacker is de rigeur.
