It's just not the immediate end of the world as they may view it, but is being more sensitive to such things being crazy?
Their claims are what identify them as crazy.
From the summary:
Today, Lumsdaine views the thread connecting GPS and drones as part of a longer-term movement by military powers toward automated systems and compared today's conditions to the opening sequence of Terminator 2, where Sarah Connor laments that the survivors of Skynet's nuclear apocalypse "lived only to face a new nightmare: the war against the machines."
When they start comparing reality to sci-fi apocalypse movies then there is a problem.
And when they start destroying things because of it, they've gone into "crazy" territory.
