They're useful for different kinds of emergencies. Nobody said one of them subsumed the other. You might as well say "when was the last time 911 helped you? I just used a first-aid kit last week and it saved me from my bleeding."
We’re one Carrington event away from coiling our own copper wire to pick up AM signals. I’m unaware of any similar mechanism for internet or cell reception. I’m pretty happy with AM being carried forward. Maybe the FCC could support that by loosening the requirements for registering and operating stations. I’d love to run my own from my house.
