Incidentally, something more to worry about:
"Why are so many would-be terrorists engineers?"

Before I read the essay, my answer was "Because most engineers are political
and social conservatives" (in the context of their own societies). His
analysis is basically the same thing, but deeper and more nuanced.

Scientists and engineers are often remarkably parochial. Their training
doesn't seem to expand their thinking. Rather, it contracts it.
