Depending on your mood, it sounds either terrifying, or like a sweet release from modernity. But solar storms hit the Earth all the time, and it's only a matter of time until a truly gigantic one fries us—it's happened before, and will again.
We're more reliant on electricity and connectivity than ever before, obviously, and we don't know how the grid will handle the power of such a storm—but we know it won't be good. The problem is, we can't test for it without, well, turning it all off and then back on again. Maybe we should do that?
