Why rule out a survival situation? While nuclear missiles would probably just end all life, there are a broad spectrum of other things that can go wrong in the next decade that just take out power grids. It would be good to be ready with more robust technology than GPS-aware microchips, I can see how it could come in handy.

I'm seeing a lot of energy security issues out there, and there are extreme economic pressures all over that could spill out in unexpected ways. There are some profoundly grumpy people out there right now.
