We've arranged a global civilization in which most crucial elements
profoundly depend on science and technology. We have arranged
things so that almost no one understands science and technology.
This is a prescription for disaster. We might get away with it for a
while, but sooner or later this mixture of ignorance and power is
going to blow up in our faces.
