Sorry but I think this article is total non-sense.
For starters he never defines what he consider as "meltdown", he just refers to it as an inflection point in history since when everything gets fucked up worldwide.
How long does it takes to build up that "meltdown"?
There is no such thing as world wide bank run, economies are related but an economic crisis in one country will take some time to affect other economies. In 1 hour you don't even have time for the stock traders to do their calls.
The government closing all their agencies and dependencies and running away like bitches? Non sense again, the gov will deploy all the alphabet agencies and will try to gain control, not just giving it away.
A lot of business will continue operating on cash if electronic media goes down.
Normal people in the worst case will be trying to get to their homes fast to check on their families, so there is no way "normal people" will start looting so soon, a lot of people travel 1 hour when public transportation works, without it it will take even more.
1 hour isn't enough for anything, the analysis that guy did is retarded.
The only part that holds true in there is where he says "nobody can predict the future, and that includes myself".
You want to know how shit hits the fan? Read history books, you'll see things go south for a long time, then in matter of days things start to get really ugly, and government for sure doesn't go home, they'll push stronger than ever.
