Hopefully this never happens.. I did hear that around 10 years ago only about 80% of our electrical substations were properly grounded against solar storms. Theoretically at any time a big enough flare could wipe out every electronic you own. If we ever get into another war with a leading nation (probably not) they most likely will use an armada of E.M.Ps or a nuclear detonation in the atmosphere. This is why people should be trained to hold onto physical addresses and the organization (the coin half) should maintain physical logs.. someday maybe our children might face not having a network. Most trucks would no longer work so it can/will cause some supply chain issues.
