Yes, satellites have succumbed to CME events, but those exist in a FAR different environment than we here on the surface do. Our atmosphere and magnetosphere protect us quite solidly, and attenuate the effects of such events whether natural or artificial. And yes, some really big CMEs have coupled to sections of the power grid, and have caused some disruption, but then, a CME is orders of magnitude larger than anything we can do, and is powered by a nuclear fusion reaction at a scale humans won’t be capable of for likely millenia.
