The catch phrase "There's no patch for human stupidity" is a fairly successful meme within the information security community, but that doesn't make it good. It's actually exotoxic in the sense that it implies that it's not worth the effort to pass on knowledge to people who don't already have it, thereby denying those people the tools with which they could better control their outcomes and by extension thrive.

The fact that we aren't still living in caves proves that it's not just special individuals who are capable of learning but in fact the entire human species as a whole.
