There are real XT hazards without having to invent nonsense. Incoming comets and asteroids could wreak havoc. A solar flare like the Carrington Event would knock out electronics and grids. But we also know a bit about the time lapses between such events, and can calculate reasonable odds about them happening in our lifetime. Doesn't mean one might not happen tomorrow, but it does mean that realistically you are in more danger, mathematically, from the car you drive.
