I see hope in what happened during the blackout in Spain/Portugal.
But essentially, with the power down, people came out as a community and life went on without technology. Granted, the power came back within a day, but I have confidence that they would have found a way.
Losing electricity causes significant disruption, emergency generators have to turn on for hospitals, the transport system stops.
The BBC is not what it once was, so assume it is no better than any other outlet in wanting to create a narrative.
The actual reality on the ground for many people would have been far from the whimsical event the BBC portrays.
Emergency blackouts are a disruption for sure and I believe people were injured in that event, but the lesson I took from it is that nothing is more reliable than community. Technology comes and goes, but we will always have each other.
