Scenario
When one software failure spreads across everything that depends on it
Payments, inventory, shipping, customer service, and scheduling increasingly run on shared automated software, including AI systems. This scenario imagines a failure in that shared layer that spreads for several days. It's a teaching scenario, not a prediction, and it isn't a case against technology. The point is that the same household habits cover it.

Why this scenario exists
Large outages have already come from ordinary causes: a bad software update, a cloud provider failure, a cyberattack on a single vendor. When many businesses depend on the same systems, one failure can hit them all at once. Automated and AI-driven systems add speed and scale to that dependence, in both directions.
What stops working in this scenario
- Card processing at stores that share a failing payment provider
- Online ordering, delivery tracking, and app-based customer service
- Store restocking, if inventory and shipping systems are affected
- Bank and brokerage apps that depend on the same vendors
- Automated phone lines that route every call through software
What usually keeps working
- Cash
- Your home stock of food, water, and supplies
- Radio and in-person information
- Local businesses that can run on paper for a few days
First 24 hours
- 1Treat it like a card outage: switch to cash for essentials.
- 2Don't panic-buy. Shelves that empty often come from rushed buying, not missing supply.
- 3Screenshot or write down balances and recent transactions while apps still load.
- 4Get updates from official sources on the radio or at local government sites, not viral posts.
Days 2 to 7
- Keep records of every payment and charge. Automated systems may double-charge or post late when they recover.
- Expect slow restocking. Eat from your home stock and keep store trips short.
- Watch for scams. Outages bring fake "refund" calls and texts. Don't give account details to anyone who contacts you first.
Buy / Borrow / Skip
Buy: the same core kit as a card outage: cash storage, document pouch, water, radio, light, power bank.
Borrow: information from neighbors and local businesses. It's often faster than anything online.
Skip: "AI-proof" or "anti-AI" products, conspiracy guides, and anyone selling certainty about when or how this will happen.
