Re: The worth
"If we get to the stage where oiks can stand on motorway bridges, press a button on their Pi-powered gizmo, can crash a stream of cars into each other, can do it time after time at any time of their choosing, we will indeed have a problem. But we are a long way from that."
So you're saying that the time to solve a problem is after it's gone into production? Surely conventional wisdom is that you build security into the design, not try to add it on afterwards. Because by the time we have that problem it will be far too late to fix it.
