If that describes the current situation, it also tells us why
"software engineering" is still very far from being a ~real~
engineering discipline. To an engineer, this sounds somewhat like
saying: "building that system of safe pedestrian overpasses was
a failure, because people are now using those for motor traffic
and there are crashes, collisions and the bridges are collapsing".
Building of a public system *must* include building of safeguards
on the way it is used. And this is clearly impossible if we keep
(if I may stretch it, but just a little) what sometimes appears
to me to be the "first principle of computer security":
"The user is an uneducated moron, and must be treated accordingly".
