I wonder if we can store enough food to feed 10 billion people for a whole year with current tech. Probably not. (Or better yet, some (fungus?) foodstuff that doesn't need light.) If this happens less than once per lifetime, it would not be profitable in the private sector. Governments are good at preparing for military-related black swans but not natural ones.
This is a major transition we will see over the next decade, and a major hope for reducing humanity's environmental footprint: foods grown from single cells.
