No doubt, many, many problems. But they would be tiny compared to cities on fire in the M.E., American trains and planes crashing, pipelines and the electric grid etc going haywire, and the internet largely down. Who would you tell? Your neighbors, by word of mouth? What would that matter, in the first few weeks?
Well, there are radios and clandestine radio stations, aren’t there? I could see an ad hoc bucket chain of dialups, computer bulletin boards, satellite links and hams and CB’ers taking shape. When info REALLY wants to get around, it will find a way, even if just leaflets on the street or stickers in bathroom stalls.
