TLDR:
We often prepare for a future disaster based on a past disaster happening again, which is rarely the case. This is because of availability bias, I.e. a recent event is more fresh in our minds so we’re more likely to think it will reoccur. We’re better served by more general preparedness.
I don’t fully agree with this, pandemics, wars, data loss, etc. seem to regularly occur. But, it is useful to think about.
