Say a massive solar storm happened and all electronic devices were rendered useless in a moment. Not just computers either. Everything not hardened for an EMP.
For the next fee years, you're gonna have to live on what you can kill or grow.
Figure the future will hold to these phases:
Disorder. As people realize what happened, they riit, loot, murder etc...
Dieoffs and famine. Basic services are broken and the disintegration of society is near complete.
Order 1. Small groups of survivors band together and the social contract is rewritten. The most valuable people are Farmers, anyone with medical experience and those with combat experience.
Order 2. The small communities band together in something like the Greek city states.
Reintegration. A new society is born.
So... Will you make it, or how far?
