It would be one HUGE, MASSIVE BIG kick in the backside for a few million cyber slaves, pissed off Black-Hat hackers, the Scam-Scum of Nigeria, Pakistan, Russia, Thailand, China and all the other lowlife scammers.
Utter pandemonium would ensue! A large part of the economic online Cyber-Biz would lose millions.
Younger people all over the planet will be totally freaking' unbearable to be around for an entire day. But they will have a full day to possibly realize what a Dumb-*** and Numb-nut waste of social drivel they exist in (though there are just as many equivalent boring adults who will have the same opportunity).
China and Japan and a few other techno-zombies will be in utter turmoil and disarray!
Wall St and Hong Kong etc stock exchanges will be devastated with possibly billions in currencies lost and company shares will be in a totally F.U.B.A.R. mess!
The rest of us will just have a nice relaxing day off and a good laugh at all the dumb sad sheeple.
A major upside to an event of such a magnitude would be that we all get a freedom day from the corrupt data agencies, NSA and similar and, best of all, Google and Facebook and all the other crappy companies' of 'Social Deviants' and their greedy thieving deceivers will be completely without paddles in a white water rapids world.
It would be like having front row seats to a live action apocalyptic virus day (like the plethora of films currently trendy in the movie media) and people like myself would be crying with laughter watching millions of sad *** pathetic Net-nuts trying to make it through the day!
PS: I love tech stuff, my computers etc. and i am one of those that society likes to call a Geek. You know! The type they'll all be relying upon to kick-start their ho-hum boring Twit-Face and Drivel-Book lives again! :)
The biggest plus for the entire world however would be knowing that Donald Trump would be on a ******** presidential S.T.F.U lock down. Now wouldn't that be worth a globally Internet free planet for 24 hours?
