Yeah, look, I know we’ve been warning you about the imminent SCADAgeddon, when the nation’s critical industrial control systems will all be hacked at once — from power grids and transportation systems to datacentre cooling systems and prison cell doors — cybering society back to the Stone Age. But forget all that.

Actually, don’t forget it entirely, because it could still happen, right? (Be quiet, you dissenters up the back.) Just start being aware — because I’m telling you now — that things are actually far, far scarier. A threat of truly biblical proportions.
