Say, some alien just wanted to mess with us, but doesn’t invade, or even care enough to want to kill us, but seeing how everyone is on their phone all the time, they decided to just jam all our radios to watch us suffer. Their transmitting power they use is so powerful, its jamming signals are 1000 times stronger than the strongest radios we have, so there’s no way we can overpower the jamming.
What does the immediate aftermath look like?
What does it look like in the long term?
(Please don’t say “kill the aliens” they have tech so advanced, its impossible to do it)
You can also buy shielded Ethernet cables (especially for installation parallel to power lines) which would be much, much harder to jam.
