Thinking about no internet and electricity is one thing, but most food now a days is made by machine's... without electricity how will the machines work, and without the machines food will have to be made by hand resulting in some products being unproductive and for the food that can be produced it would go up in price by a lot and governments taking money from us to fix the damage which would result in a lot of poor people just struggling to survive, selling goods like PS3 and TV's for money to buy food and even when electricity returns and internet you wont be able to afford it. So yeah were f**ked.
your forgetting 1 thing.
