We will never really plan for what actually happens. A few scenarios, some of which a lot of businesses cannot prepare for:
1. Space weather. Could you cope with electricity and telecoms being down for days/weeks? It nearly happened in 2012.
2. War. Middle East, India vs Pakistan of China (all have nukes), China vs US (even just a cold war would be highly disruptive to trade), lots of other possibilities.
3. Large scale internet disruptions caused by "cyberwar" or sabotage of telecoms (e.g. snipping a few undersea cables). In both cases it can be tricky to be sure who did it.
4. A vital supplier or customer of your business going under.
5. Local disruptions to transport, telecoms, etc.
6 Right now recession is to be expected, not just a possibility.
Of those, I can do something about 5 or 6. I can diversity exposure to limit the damage of 4. I can do very little about the other 3.
Lots of possibilities. Often the worst things are black swans (by definition, something no one really expected).
But she has these annoying zoom conference things and I keep having to turn the music down, supply coffee, answer questions and not potter about in my dressing gown.
A friend of mine "pottered around" naked through the background of his wife's work zoom call (on his way to the shower).
