Scientists are rightfully worried that our current solar cycle might trigger an electronics collapse of anything not electromagnetically shielded. The weakest link is the electric power grid — which we all depend on nowadays — and some of the aging satellite systems that do not have military grade hardware protection. Can you imagine all electronics either fizzling out or bursting into flame?
In decades past, the few key electronic systems that existed worked at higher voltages than today’s machines and at lower frequencies, making them less sensitive to EM disruption. Today, though, any digitally controlled infrastructure presents a target: Power, telecommunications, finance, water, natural gas, and more are all coming under the ever-finer control of computers.
