Entities are dependent upon the operational integrity of their customers, their suppliers, their financial services providers, their outsource contractors, their federal, state and international regulators, et cetera. This future is the one towards which most official policy is directed. In this future, technological glitches will be spotty, and one failure will not cause others. For the most part, it'll be business as usual. This is the doom and gloom story.
People die of starvation.
The health care system collapses. Its every person for themself. Entities that do not now rely upon sophisticated interconnected systems gangs, third world countries, etc. will be at a competitive advantage. For example, a one-day shutdown of a single bank might cause many people to want to withdraw money from many banks at once. Or a temporary gas shortage will lead everybody to fill up, creating systems failures that are not directly date-glitch related.
